Plastic runway according to its construction structure, materials can be divided into: prefabricated components of plastic runway, plastic runway, ecological plastic runway, composite plastic runway, hybrid plastic runway, breathable plastic runway, EPDM plastic runway six categories. Plastic runway is also known as all-day soccer sports playing field, it is composed of polyurethane material prepolymer, mixed and methacrylate, waste tire rubber, EPDM vulcanized rubber granules or PU granules, color paste, modifier, filler. Ecological plastic runway with good flatness, high tensile strength, strength ductility moderate, smooth process performance characteristics, beneficial to the full play of the rate and technicality of the players, reasonably enhance the fitness sports test scores, reduce the rate of falls and injuries. Plastic runway to take safety protection measures, it can be very good to reduce the sportsman sports injury, composite plastic runway features: 1. hybrid plastic runway color: special polyurethane particles, soft surface color, granular surface layer, to prevent the reflection of sunlight, beautiful and long-lasting, and can be used with multi-color. 2. Economy: Convenient maintenance, save governance spending. 3. Safety: It can reduce the sports injuries caused by the fall of sportsmen. 4. Adhesion: special construction treatment, strong adhesion, can hold down the rise of moisture, no blistering, no peeling and other phenomena. 5. Eco-plastic runway flatness: construction using self-leveling materials, the surface is flat, in line with the requirements of particularly flat competition venues. 6. Impact resistance: with a strong elastic layer and buffer layer, can absorb strong impact, the surface will not be damaged. 7. Spike Resistance: In the 100 meter starting point, which is the most heavily used, it will not be damaged by spiked shoes or starting frames. 8. Abrasion resistance: not due to the heavy pressure of track and field equipment and can not restore the elasticity. 9. Eco-plastic runway abrasion resistance: abrasion resistance is less than 2.5%, to meet the needs of all levels of schools and universities for long periods of high-frequency use. 10. Impact absorption: moderate absorption of foot impact, reducing sports injuries, long-term training and competition are appropriate.

In order to make the ecological plastic runway service life longer, not easy to appear breakage phenomenon affects the use of plastic runway, so no matter what the season is to carry out proper maintenance of plastic runway, then in the burning hot summer hybrid plastic runway what maintenance methods? First, clean up the water left by the movement in a timely manner, prohibit the ecological plastic runway immersed in stagnant water, although some of the ground selection of waterproof rubber spacing water, but a long time of immersion, will also seriously affect the service life of the plastic runway. Cleaning process in a timely manner with a water absorber to suck the sewage dry, after cleaning a small amount of residual water on the surface of the glue can be wiped away with a dry cloth. Stained with oil can be 10% ammonia or detergent, washing powder scrub clean. Second, avoid smoke and fire and isolate the heat source, avoid breathable plastic runway contact with organic solvents, chemicals, cigarette butts and other fires, pollutants, etc., by diesel pollution and corrosion of the root part of the firmly dug out, fill in with glue. Third, athletes in the ecological plastic runway after the activities, sweat or drinks spilled on the plastic runway, site maintenance personnel to shovel the site in a timely manner on a variety of dirt and stagnant water. Fourth, should pay attention to fire prevention summer climate is very hot, dry, to avoid ecological plastic runway fire, plastic runway in the conditions of a certain drainage facilities, adapt to all-weather use. Eliminate flammable items into the plastic runway, prohibit hard, rough cleaning utensils to avoid sharp objects bumped into the ecological plastic runway. Fifth, on the high traffic, plastic plastic runway wear and tear of the local should shorten the protection cycle, pay attention to the margins, shall not be arbitrary lifting, such as the discovery of the road teeth damage, blistering phenomenon should be timely to allow the construction unit to protect, remember to prohibit vehicles driving on the runway, piling up heavy and sharp objects.

With the rapid development of China's economy and the improvement of people's living standards, more and more people have begun to pay attention to physical exercise, especially in the past decade, the concept of health has been deeply rooted in people's hearts, and more and more people are keen to maintain their health through exercise. As a result, many schools and stadiums are paying more and more attention to the infrastructure of their venues. Here, I will tell you about the all-plastic plastic runway. All-plastic plastic runway is made of SPUE material, which is a new type of environmentally friendly material with high strength, high elasticity, wear-resistant and weather-resistant. It adopts new environmentally friendly raw materials and fine processing requirements for precision production. It is not only safe, but also can well meet the needs of sports. The abrasion resistance of SPUE plastic surface material is 20 times that of C60 concrete, and the tensile strength and elongation are far more than 10 times that of the national standard.SPUE is not only of good quality, but also has a long service life, which is more than three times that of similar high-quality plastic materials. SPUE material contains no solvents, zero chlorine paraffin, zero benzene and its cognate compounds, no TDI, no toxic or heavy metal substances, the product is environmentally friendly and clean. It has passed the national 19 items of heavy metal environmental protection test, is a real safety and environmental protection products. All-plastic plastic runway product adopts all-plastic structure, does not contain any impurities, more environmentally friendly and more stable. Single-component solvent-free material, does not contain chlorinated paraffin, MOCA, toluene diisocyanate, solvents and other harmful substances, non-toxic and tasteless, safe and environmentally friendly. Compared with the traditional runway materials, the abrasion resistance of all-plastic plastic runway surface is 20 times that of C60 concrete, the tensile strength and elongation is 10 times that of the national standard, and the service life is more than 3 times that of other high-quality products. It not only slows down the impact on each joint of the human body when the athlete lands, but also enables the human body to obtain stable positive kinetic energy.

For the construction of plastic runway conditions, although not very harsh, but also should pay relative attention to some matters, such as can not meet water, or debris will affect the quality. If you encounter these emergency situations during construction, what should we do? 　　1. Rain: in the plastic runway construction process suddenly rain, first of all, should immediately stop the ingredients, and then use the pre-prepared plastic film to cover the motor, mixer and material barrels and so on. If the mixer has been stirred in the slurry should be immediately poured into the slurry in the car, when the garbage disposal. 　　2. windy: in the plastic runway construction process windy, the same place should first immediately stop batching, paving process. If you find that there are debris scraped into the slurry or on the liquid surface, the debris should be constantly removed. 　　3. Power failure: If power failure is found during the batching process, first check whether the circuit can be repaired in time, if it can be, then it should be repaired immediately, if it can not be repaired in time, stop batching immediately. At the same time, notify the paving process to prepare for the shutdown, if the mixer has material should be disposed of garbage, pay attention to these plastic runway construction matters to ensure that you can use the process in the future can be a better experience. 　　Hebei Tianyou Sports Facilities Co., Ltd. can undertake all kinds of modern sports venues and facilities construction, professional laying of various types of plastic runway, artificial turf and various types of stadium surfaces, sales and installation of various types of ancillary facilities in the stadium, the company since its inception, "continuous innovation" is the fundamental survival and development of the enterprise, the strong technical force to make the enterprise every year, new products into the market. New products into the market, there are now dozens of products for customers to choose from, but also according to user needs for design, construction.

With the increase in the use of time, plastic runway degranulation and small area damage is inevitable, so plastic runway manufacturers believe that for the renovation needs of users, to understand the relevant plastic runway renovation points of attention is necessary. 　　First of all, the professional and technical personnel according to the spot survey or photo observation of the damaged condition of the plastic runway. Generally speaking, the total area of damage is small, the damage condition is light only must be simple to the structural layer of the plastic runway paved again, and in the case of more serious damage must be the overall basic repair up. 　　Secondly, the sports field before renovation should be resolved to unnecessary dirt, that can ensure the bonding of polyurethane materials and plastic structural layer of the thin thickness of the proportionality, after the construction team will be able to carry out the sports field pavement construction, painting and other processes, in order to ensure that the sports field of the actual effect of the repair, should be the plastic running track all places closed up, and hang up the warning signs. 　　Finally, after renovation and repair of the sports field must be maintained 7-10 days before it can be delivered for use. In this whole process when to pay attention to the plastic runway water sprinkler equipment, enhance the ductility of the plastic runway pavement. 　　The above is a summary of some of the problems that need to be paid attention to the renovation of plastic runway, I hope to be able to help you. If there is a need to contact us at any time, we are a professional plastic runway manufacturers!

Nowadays, the country's economic development, most of the schools have begun to build sports programs related to sports facilities, including plastic runway is the key to sports facilities. So today we will talk about the school runway which runway is more suitable. 　　Now the prevalence of domestic runway generally have breathable, composite, hybrid, EPDM type, and all plastic type of these five categories. Campus is not only a place to teach and educate people, but also a place to improve the general physical fitness of students, the general campus runway will be prioritized in the selection of runway materials, elasticity, wear-resistant and other aspects to consider. The scope of application of hybrid plastic runway is very wide, and hybrid plastic runway can just meet these requirements. 　　Hybrid plastic running track has the following characteristics: 　　1. elasticity: hybrid plastic runway has the right elasticity, can be a proper rebound force on the athletes, together with the protection of athletes joints and ligaments, reduce the risk of injury. 　　2. abrasion resistance: the outstanding abrasion resistance of the plastic running track can ensure that the structure of the plastic running track is stable for a long time, and can be applied to running shoes with spikes below 7mm. 4. stability: the hybrid plastic running track has a proper elasticity to the athletes. 　　4. stability: hybrid plastic runway has excellent anti-aging and resistance to salt spray, heat and humidity, ozone, ultraviolet function. Inherent physical and mechanical properties and the appearance of structural features remain constant, extending its service life. 　　5. Practicality: plastic runway is all-weather runway, with proper drainage system, after heavy rain or washout can also be used immediately for training, competition and games, and its performance remains unchanged. 　　6. Anti-slip: The special cover layer of the plastic running track ensures that its appearance is not slippery, providing athletes with a safe feeling of contact and stability. Even in wet conditions and bad weather can also ensure that athletes feet solid, start, accelerate, run fast and safe. 　　7. Simplicity: hybrid plastic runway in its reasonable use without special protection. But daily cleaning, flushing is necessary, proper protection can improve its service life. 　　Mixed plastic running track surface layer thickness uniformity, bright color, flat cut, outstanding elasticity and anti-skid, can effectively protect the leg joints of the sportsman, to avoid accidental injury. All materials used are non-toxic, harmless and regenerative, beneficial to the protection of the environment and human resources. The appearance of plastic sports ground costs more, but its durability, coupled with quality service guarantee, therefore greatly reducing the cost of labor maintenance, so this is the reason why many campuses will choose it.

Plastic running track material has been used more in our life, especially in many large playgrounds and sports fields, do you know what to pay attention to when using plastic running track material? At this point, our plastic running track material manufacturer will do a simple analysis for you. 　　1, plastic stadium has a certain drainage facilities, can be adapted to all-weather use. The ceiling height or minimum obstacle should be at least 7 meters, and the main application of hybrid plastic track is the semicircular area in outdoor track and field. 　　2, plastic track material is only used for sports training competitions, shall not be used for other purposes, the bottom layer is laid by special paving machinery, completely by PU (polyurethane) adhesive and special rubber particles mixed. 　　3, athletes must wear special sports shoes, the length of the nails should not exceed 9 mm, jumping shoes generally should not exceed 12 mm, if the sports shoes with longer nails, it is not allowed to use in the plastic running track material; machine cross spraying secondary surface spraying particles. 　　4, plastic runway material paving is completed, need to maintain 7-10 days to use, all levels of competition, school teaching and training runway venues should be concentrated in the midpoint of the center line. 　　5, the edge of the plastic runway material should be protected, not arbitrary lift, if found damaged, should be repaired immediately. Its role is to reduce the length of other competitions by 4 meters under the control of the ballclub.

Large sports venues are very troublesome to pave, used to use fine gravel to pave, to prevent the site after the rain is too muddy, but also will be more tidy, and gravel construction cost is relatively low, can be used in large areas. If the site is very large, gravel can save a lot of money, paving construction is also much more convenient, but there are also disadvantages, once the injury will be very serious, the greater the amount of sports, the more danger, so there will often be athletes injured, light rubbed skin, heavy also easy to fracture, etc., athletes in such a field activities should be extra careful, but also affects the game to play. 　　Now large sports venues, many have begun to pave plastic runway, looks more neat and beautiful, bright colors. And the service life of the plastic runway is long, strong abrasion resistance, will not be easy to wear out, athletes can move around at will, and long-term use is not easy to be bad, and do not have to worry about ultraviolet damage to it. The surface layer of the plastic runway is made of rubber, so this aspect can be completely at ease, after paving can be used for a long time, maintenance is not particularly difficult. 　　So what should I pay attention to when laying plastic runway in large sports venues? First of all, we should consider whether the manufacturer is equipped with professional construction personnel, if you just buy their own materials to lay, may not find a professional construction team, then finally laid into the plastic runway, may not be as expected. Plastic runway in the laying of a lot of attention, especially the larger the area, the more attention to each link, a link is not good, it is easy to affect the overall use of the effect and aesthetics.　　　　 　　Plastic runway in paving, the site must be cleaned up first, there can not be debris, some large particles should be cleaned up in a timely manner, if there are uneven potholes in the area, but also to pad the leveling of some of the paving can begin, and at the same time to ensure that the site is dry, just after the rain is not suitable for laying a plastic runway site to be naturally dry can be.　　　 　　Each layer of plastic runway material paving, should check the leveling, only each layer is kept level, the final runway will be level, when used will be much more convenient, runway paving is also not immediately used, to wait until thoroughly dry and hardened, but also let the smell dissipate, so that athletes in the use of the safety of the time.

Plastic runway degumming phenomenon is a frequent occurrence, why do you say so? Because many manufacturers of materials and construction team of incorrect construction methods can lead to problems, specifically by what causes, and how to fix it? The following TECS sports to introduce you in detail. 　　First, the edge of the plastic runway degumming is what causes? 　　1, surface rubber cracking 　　Generally in the plastic runway delivery after use, after exposure to sunlight or precipitation infiltration will appear after this situation, the first pu glue in the construction of plastic runway, raw materials in the middle of the adhesive must be glued together, then this kind of adhesive is often said that the pu glue, if the pu glue is not off will cause the actual effect of the adhesion of the poor, then deglossing is bound to produce the problem. Second is the particulate matter raw materials, the most common raw materials is eppdm particulate matter raw materials, generally not pass the eppdm particulate matter through the sunlight will appear molting, may lead to plastic runway deglossing problem. 　　2, basic cracking 　　The basic cracking cause is the foundation project construction is not pass, resulting in the place of disproportionate foundation settlement, which leads to basic cracking. The glue of the poor resistance to base cracking, the structural layer and then by the basic cracking amplitude ripped leading to structural layer cracking. 　　Second, how to repair the plastic runway edge degumming? 　　1, remove 　　In the damaged position drawing line marking, with a wallpaper knife along the outer edge of the drawing line evenly removed. Dig to a similar ring-shaped pit, along the outer edge of the removal of a 5mm wide steep slope, followed by cleaning and tidying the sand at the bottom, drying the foundation base. 　　2、Make up 　　For the repair position in accordance with the plastic materials prepared in advance to carry out plastic ductile layer repair, near the border to ensure that the delicate and even, thin and thick moderate. 　　3、Spray paint structure layer 　　This procedure is a very critical plastic runway processing technology, divided into 2 times engineering construction, that is, must be interspersed with two times of spray paint. The first and second time the orientation of no actual very stipulated, but must be differently skewed spray paint, and no significant connection head after spray paint.

Generally speaking, there is no rigorous construction of composite plastic runway will appear to bulge the phenomenon of bubbles appear, some area is relatively small, some are very large area, it looks very scary. If there is such a problem should be how to deal with it? The following TECS sports to introduce some of the methods of treatment. 　　1, if the composite plastic runway only a small part of the bulging condition, you can cut off the bulging area, and then in the place of dry conditions, repair again. If it is a large-scale bulging, it is recommended to pave the rubber runway again. 　　2, if the construction site encountered bulging problems and bubbling problems, then check the construction period of raw materials are not product quality problems, if product quality problems, please remove and replace as soon as possible, the use of qualified construction and decoration materials. If it is caused by the construction of the project, and the raw materials have no problem, then a part of the structure will be eliminated and paved again before. 　　3、If vapor bubbles are found after the construction work is carried out, and it has condensed, then it is necessary to dismantle the materials that have already been installed, and cut them by laser with a CNC blade, and then rebuild them with new materials. If the total area is relatively small, then the same tone will be completely removed and carried out again. 　　4. If the area is very large in relative terms, and the whole area has the same color tone, then the destroyed part will be cut into geometric shapes. For example, square or ring shape, easy to repair after still basic patch type. 　　5, composite plastic runway bulging, often due to bad quality or construction is not serious and meticulous problems. It is recommended that in the selection of place engineering construction of the elite team, to take into account in all aspects, from the enterprise engineering construction work experience, technical, historical time, service projects and its user evaluation. That can prevent the place destruction and other conditions in the whole process of future application.

General plastic runway will be added in the middle of an artificial turf, used to play soccer or other sports. But want to do a good job of this lawn is not so simple, specifically how to properly construct it? The following tianyou sports to share the engineering steps. 　　1, work measurement and construction sampling 　　Apply the level meter or other electronic measuring instruments, measure the nearby equipment is not in line with the specifications of the sports ground. If there is not suitable for the place to be changed in a timely manner, the allowable deviation ± 5mm. 　　2、Non woven geotextile laying 　　1) When laying non-woven geotextile, the textile must be flattened without wrinkles. Reinforcement overlap part of the overlap must not be less than 20-30cm, part of the overlap must be sprayed with sufficient leachate to achieve sufficient mixing. 　　2) After paving non-woven geotextile, vulcanized rubber tire roller can be applied to pave the ground of plastic runway to ensure that the non-woven geotextile and rural substrate to meet and allow leachate through the non-woven geotextile. 　　3, grass paving 　　Paper cut nails soccer field wire frame, wire frame must be vertical, according to the original specification type paving in the basic, artificial turf middle need reinforcement lap 3-5mm, connected to the grass laser cut flush, the joints should not exceed 3mm, cut area under the brush over the close connection glue and non-woven geotextile bonding, to be dry after joining splicing and knocking solid. 　　4, engineering construction steps 　　1)Construction coating: stipulate in the surface layer brush coating thin thickness, can not constantly point glue, otherwise there will be out of the bubble condition, and even fall, point glue to each wipe being bonded two bonding surface. 　　2) adhesion: based on the specific hazards of temperature and humidity, standard air pressure and other standards at that time, effectively manipulate the drying time, generally 10-15 minutes after gluing to hand touch non-stick is appropriate. 　　3) Charge pressure: after the artificial turf glued well, eliminate its surface layer of dirt. With special type of rubber lawn character outward hammer from the bonding place to both sides of the hammer, so that its surface layer is sufficient to touch the denseness, bonding is more solid. 　　4) dry and solid: its dry and solid time is generally three days, test compressive strength of one for ten days, during the period to prevent excessive exposure to the sun, soak and move, in order to do the bonding of a good situation.

Plastic runway in the choice of good materials, the first thing to do is to do the construction of the bottom layer, because only this one is done, the latter work can be normal to cast open. So how to deal with this bottom layer? The following TECS sports to introduce some of the steps of the bottom layer construction program. 　　First, deal with the process 　　1, plastic runway bottom layer paving, in the non-dry solid before the mixing of black sealing rubber are poured on the road surface, with a special type of asphalt paver, according to the design of the conception of the thin thickness of the mechanical equipment leveling and tamping, in order to manipulate the use of the amount of and the thinness of the thickness. 　　2, plastic runway bottom layer paving the whole process, paving staff to ensure that the equipment walking rate is proportional. Crimping staff to posture skillful, immediately on the leakage of the bottom, concave to carry out the replenishment of glue, protruding position scraping, edge neat and flat, crimping staff not less than a few. 　　3, paving and other black sealant after drying, the whole field to carry out inspection. Found that the bottom edge is not flush or have convex and concave place, to carry out cutting, sanding and polishing, make up glue and refurbishment solution to ensure that the surface of the rubber pavement of the thin thickness. 　　Second, the precautions 　　1, maintenance construction site 　　Plastic runway construction site near as much as possible to set up engineering enclosure, to ensure that the gear wind, blocking soil, blocking people, engineering enclosure itself to have credibility and reliability. 　　2、Clear the site 　　Try to remove the construction site stock basic surface of the residue sediment. If there are all volatile organic matter oil stains, try to thoroughly multi-directional removal. 　　3、Maintenance of the current construction works 　　With tape stick in the bottom engineering construction work intersection surface, cause the maintenance of the efficacy, so that it is not easy to suffer from the environmental pollution of the natural environment of engineering construction, the first thing should be taken into account the factors that should be taken into account, such as not to destroy the surrounding facilities, how can we build this bottom better. 　　The above is God bless sports for everyone to bring about the "plastic runway bottom layer processing process and considerations" content, I hope to be able to help you!

There are all kinds of plastic runway in life, not only the application is different, its size, material, construction and so on will be different. So how big is the standard area size of plastic runway? The following TECS sports to introduce to you. 　　First, the plastic runway area 　　1, kindergarten sports field: standardized kindergarten sports field for 1 m 22-1 m 25 wide, 6 sports field; non-standard sports field of the actual based on the size of the place, their own decision-making. 　　2, junior high school sports field: general junior high school sports field is 300 meters 6 sports field. Its turning half longitude is 26.3 meters, parallel lines 67.23 meters, divided into 1.22 meters wide, divided into graphic boundaries 5cm, the whole part of the total width of the road is the same. 　　3, primary and secondary school sports field: general primary and secondary schools are two hundred meters 6 sports field. Its turning half longitude is 15.65 meters, the length of the straight road is 50.206 meters, divided into a total width of 1.22 meters, divided into graphic boundaries of 5cm, the whole part of the total width of the road is the same. 　　Second, the size of the plastic runway 　　The standardized plastic runway generally refers to 400 meters of track and field sports plastic runway. Sports field half by the number of design options for 36 meters, a total of eight lanes, the first lane is 408 meters long and short, the third lane is 415 meters long and short, the fourth lane is 423 meters long and short, the fifth lane is 430 meters long and short, the sixth lane is 438 meters long and short, the seventh lane is 445 meters long and short, the eighth lane is 452 meters long and short. 　　The above is the day to introduce you to the "plastic runway standard area and size" of some of the content, I hope to help you! Of course, it is not that must be done in accordance with these standards, or according to the actual environment to decide, but not below this standard parameter.

1. The standard runway is 400 meters in length and shall consist of two parallel straights and two curves of equal radius. With the exception of grass runways, the inside of the runway shall be demarcated by a cornice made of suitable material. The prominence shall be approximately 5 centimeters high and at least 5 centimeters wide. 2. The length of the runway shall be measured 30 centimeters beyond the outer edge of the inner cornice. If there is no protrusion, it shall be measured 20 centimeters beyond the outer edge of the marking line. Note: The IAAF Handbook of Athletics Facilities contains all the technical information on track construction, design and marking. This rule gives the basic principles that should be followed. 3. For all track and field events of 400 meters and under, each athlete shall occupy a divided lane with a minimum width of 1.22 meters and a maximum width of 1.25 meters, with a divided line of 5 centimeters wide, and all divided lanes shall be of the same width. The length of the first lane shall be measured in accordance with paragraph 2 above and the length of the other lanes shall be measured 20 centimeters beyond the outer edge of the inside lane line. Note: The lane splitting width shall include the right-hand lane splitting line Plastic runway is constructed on asphalt or cement foundation, and the foundation practice is more or less the same as road construction. The surface flatness of the foundation is required to ensure the consistent thickness and uniform elasticity of the plastic surface layer, and the quality requirements of the foundation are as follows: Slope: horizontal <1% (curved road 8 ‰, straight road 5 ‰, semicircular area 5 ‰), longitudinal <1 ‰, high jump area <0.4%, the surface should be flat and smooth, smooth drainage. Flatness: the pass rate of flatness is above 95%, and the error of 3 meters straightedge is 3mm. Positioning: In order to accurately construct and draw lines, four semi-circular tangent points and two centers of the runway site should be marked out by firm and distinctive markers. Drainage: Drainage system must be discharged two hours after heavy rain. In frozen areas, it is best to add a layer of geotextile buffer layer between the asphalt layer and the gravel layer. The foundation along the drainage trench should be specially waterproofed. Strength and stability: the foundation should have certain strength and stability, with even and solid surface, no cracks, no rotten edges, and straight and smooth joints. The cushion layer is compacted, with the degree of compactness greater than 95%, and there is no significant wheel tracks, floating soil loose, waves and other phenomena after the medium-sized roller has been pressed.

(1) polyurethane plastic materials in the construction process is most afraid of water, paste in the initial curing before touching a drop of water will produce a large bubble, so construction workers in the high-temperature conditions should be prepared to towel sweat. Pave the rubber surface must grasp the weather conditions and to do a good job to prevent sudden showers of emergency measures. Lay rubber time to avoid the morning in the atmosphere and the ground when the humidity is large, even in the weather clear normal working days, generally in the morning after nine o'clock formally laid. (2) The actual thickness of the rubber surface is from the bottom of the rubber to the center of the surface layer of rubber particles, generally from two aspects of control. First of all, through the standing mold for the thickness of the size of the pre-check, first of all, the grass-roots level of localized high out of the place to repair chopping or hammering for tamping low. If not much higher, can be used on a flat scraper with a clamp off the mold scraping slurry to ensure the thickness, the 11th Asian Games North Suburbs Competition Ground Plastic Runway main competition area to ensure the thickness of the error control for the positive difference, so the average thickness of more than 14MM. (3) plastic runway after the rain does not accumulate water construction experience: A, in order to ensure flatness, paving span as large as possible, the main runway on the span of 3.66 meters (three road paving at the same time), non-competition area span is greater than 4 m. B, generally in the north and south semicircle after the rain is sure to have a partial accumulation of water phenomenon, especially high jump area semicircle is more serious. In order to ensure that the slope, the use of "turtleback" construction method, in order to facilitate drainage. (4) to prevent the rubber surface after paving local blistering and shelling, for the grass-roots level of compactness should be strictly controlled to prevent the asphalt base layer of its own embedded extrusion is not solid, shelling and delamination, resulting in poor adhesion, surface vaporization, the rubber surface is pulled off. Grass-roots compactness is not enough places, you can use drill holes, filling rubber (rubber nails) method of reinforcement. (5) in order to ensure the flatness, slope, mold strip nailed, with a level meter to simulate the correction, grass-roots level of individual high places, the first to be smoothed out, individual low places, fill in with rubber. (6) by the diesel pollution and corrosion of the base part of the firm digging out, fill with glue.

Whether it is a plastic runway, or plastic stadium, can not be separated from the word plastic, and plastic has an indistinguishable link. Plastic has a material called polyurethane plastic, this material in the construction process is afraid of encountering water, glue paste in the preliminary into the glue before if accidentally stained a very small drop of water beads, then long will appear on the top of a very large bubbles, so the personnel repeatedly emphasize the plastic field construction personnel if it is in the high temperature weather conditions work, be sure to have a good towel ready at any time to wipe away the sweat. And, in the process of laying plastic venues, must do a good job of preventing rain, so as not to cause a large area of plastic bubbles. Because of the sports on the sports ground quality requirements are very high, the construction of a little careless will affect the entire site of the perfect degree. Because of this, focusing on the quality of each square foot of plastic field, only frequently emphasize the importance of waterproof work during construction!

Construction method of cement stone chip stabilized layer: 1）After the road bed has been accepted, the raw material is mechanically mixed according to the design ratio; (2) Pave according to the designed thickness, elevation and width, and finally roll it with 8-12T roller until there is no obvious wheel track.
