Introduction to Plastic Track
The plastic track is also called track and field track. It is composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives, and fillers. The plastic track has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. It is conducive to the athletes' speed and technology, effectively improving sports performance and reducing the rate of falls. The plastic track is composed of polyurethane rubber and other materials. It has certain elasticity and color, certain UV resistance, and aging resistance. It is internationally recognized as the best all-weather outdoor sports field floor material.
Breathable Plastic Runway
Breathable plastic runway introduction
Breathable plastic runway, also known as permeable runway, is widely adopted in rainy areas because of its good air permeability and water permeability. The breathable plastic runway has the advantages and performance of a general runway, and is low-cost, making it one of the mainstream products for the surface layer of the plastic runway. The breathable plastic runway produced by our company is generally paved with a professional paver, and the flatness is effectively controlled. In addition, the surface layer is sprayed with a professional sprayer, and the content of polyurethane glue is very high. Therefore, compared with other types of runways, the surface layer is relatively strong, and no maintenance is required during use, which greatly reduces the maintenance cost.
Breathable plastic runway introduction
The bottom layer of the breathable plastic runway material is a combination of single-component glue and elastic rubber particles. It is an environmentally friendly product with a breathable function. At high temperatures, the steam generated by the foundation will quickly dissipate. The steam pressure cannot be focused, so there will be no bubbling phenomenon, and it meets professional requirements and has good elasticity.
1. The surface layer uses EPDM (ethylene propylene diene monomer) particles, which makes it highly resistant to ultraviolet rays. The practice has proved that it does not fade and is highly wear-resistant.
2. No particles fall off. The EPDM particles of the surface layer are mixed with polyurethane slurry and prepolymer and then mechanically sprayed for construction.
3. Excellent weather resistance and not easy to age.
4. Stable elasticity, no difference in elasticity throughout the year, not hard in winter and soft in summer.
5. Strong power rotation and shock absorption, emphasizing the comfort and safety of athletes, helping athletes to perform or improve their performance. Emphasize the overall performance of the runway, adapt to various events and long-term competition training, etc.
6. The paint is not easy to fall off, the color is bright, it does not fade, and the wear resistance is better.
7. The flatness meets the IAAF standards, the water filtration is good, there is no need to stop the competition on light rainy days, and the competition can be immediately after heavy rain, and there will be no water accumulation.
The construction process of breathable plastic track
The breathable plastic track can be based on cement concrete, and the foundation requirements should have a certain strength and stability. There should be no cracks or uneven frost heave caused by freezing. A cushion layer should be added in the strata with high water content. In cold areas, the foundation should be thickened, or anti-frost heave measures should be taken according to the local geological conditions. The thickness of cement concrete is generally required to be around 120-150MM, the flatness requirement is that the error of a 3-meter ruler should not exceed 3 mm, the strength requirement should reach C20 or above, and the surface slope should be 6%-10% from the outer edge of the runway to the inner edge (drainage ditch), and 8% is recommended. Cement concrete should be cut every no more than 6 meters, and 4-5 meters is recommended. The standard curing period for cement concrete is recommended to be 28 days. In the case of poor flatness, it is strictly forbidden to use pure cement mortar to make skin-like leveling, which should be handled during the surface construction.
Application Scope of Breathable Plastic Track
International competition tracks, national competition venues, professional sports school training and teaching venues, ordinary school teaching venues, professional gymnasiums, and multi-functional stadiums.
Breathable Plastic Track Construction Process
※Use a roller brush to evenly apply the single-component glue or primer on the cement foundation.
※Before the primer is cured, mix the single-component glue and EPDM particles in proportion with a mixer and transport them to the paver for paving according to the specified thickness; after curing, it becomes an elastic layer.
※Use breathable spray glue and EPDM particles and EPDM rubber powder in the specified proportion, stir evenly, pour into a special sprayer, and spray two to three times in clockwise and counterclockwise directions. After curing, it becomes a non-slip and wear-resistant layer. The commonly used colors are red and green.
※Draw lines according to competition rules or user requirements
Composite Plastic Track
Introduction to composite plastic track
There are two types of composite plastic tracks. One is to spread 8-9MM with the elastic layer of breathable plastic track and spread 4-5MM with EPDM particles on the surface layer. The spreading method is the same as the elastic layer. This process is simple to construct, but the surface layer is relatively flat, more suitable for courts, and is generally not adopted.
The other is a track that combines a breathable plastic track and a mixed plastic track, that is, a track made of the elastic layer of the breathable track and the surface layer of the mixed track. It is generally suitable for the case where the foundation is a cement concrete foundation and the surface layer is required to be mixed. The composite track produced by our company not only ensures the stability of the combination of cement foundation and plastic bottom surface, meets national standards, mechanical paving, mechanical spraying, excellent flatness, and no threshing phenomenon but also improves the grade of the surface layer. It has pores, is water-permeable and breathable, has excellent elasticity, and has no blistering. It can be used all-weather, has strong resistance, good weather resistance, strong compression resistance, good impact resistance, and is strong and durable. The price is economical, providing users with more choices for laying a satisfactory runway.
Construction technology of composite plastic track
※Use a roller brush to evenly apply the single-component glue or primer on the cement foundation; before the primer is cured, mix the single-component glue and EPDM particles in the specified ratio, stir them thoroughly with a mixer, transport them to the paving site, and spread them with a paver according to the specified thickness: after curing, it becomes an elastic layer.
※Construction of anti-seepage layer: Use the A and B components of the two-component hybrid runway paving material to mix them in the specified ratio, stir them evenly, and remember to add an appropriate amount of catalyst according to the changes in temperature and humidity to form a hybrid runway paving composite material, add an appropriate amount of quartz sand to it for scraping and sealing, and wait for it to cure.
※There are two methods for making anti-skid and wear-resistant surface layers: removing particles and spraying: the process of spreading particles is to scrape a 2mm thick composite material on the elastic layer, and evenly sprinkle EPDM particles or PU particles manually. After curing, the excess EPDM particles that are not attached to the surface are swept away, and finally, a layer of reinforcing glue is sprayed on it;
※The spraying process is to add an appropriate amount of EPDM particles to the spray surface and stir evenly, and directly spray it on the surface of the elastic layer with special spraying equipment.
※Use polyurethane marking paint to accurately measure the position of the process line according to the current standards for track and field facilities, and then spray it.
Features of composite plastic track
※The cost of the composite plastic track is about 15% lower than that of the mixed plastic track;
※The upper layer of the composite plastic track is PU particles or EPDM weather-resistant environmentally friendly colored particles, water-permeable polyurethane seal, and the lower layer uses a mechanical construction buffer pad;
※The composite traditional plastic track has a good surface drainage function. Rain and snow in high-cold areas cannot enter the elastic layer of the plastic track. Once the climate warms up, the ice and snow melt on the surface of the composite traditional plastic track. Through the natural drainage of the slope of the track, there is no adverse effect on the track;
※The composite plastic track is generally suitable for cement concrete foundations, and the surface layer requirements are like the mixed type. Shanghai Yibangli composite plastic track meets national standards, mechanical paving, and mechanical spraying, excellent flatness, no threshing phenomenon, improves the grade of the surface layer, has pores, is water-permeable and breathable, has excellent elasticity and no blistering phenomenon;
※ The composite plastic track can be used all-weather, has strong wear resistance, good weather resistance, strong compression resistance, and good impact resistance, is strong and durable, and is economical price:
※ Compared with sports venues such as breathable plastic tracks, hybrid plastic tracks, and precast rubber tracks, the composite plastic track sports venue has the same appearance as the hybrid plastic track, and other data except tensile strength are the same as the hybrid plastic track.
Hybrid Plastic Track
Features of hybrid plastic track
Hybrid plastic track, also known as a traditional track, has a flat and dense structure. A hybrid plastic track is generally used in professional competition venues and is a common type of mid-to-high-end track and field stadium. It is recognized by many users for its superior physical properties and good appearance quality. Our company's hybrid track uses high-quality and environmentally friendly two-component hybrid track special paving materials, which can be used for up to 15 years. The track base is divided into a cement concrete foundation and an asphalt foundation. The flatness is within 3 meters, the height difference is not more than 3 mm, the leveling qualification rate is greater than 90%, and the inclination is 3%-8%. For other technical requirements, please refer to the technical requirements for the construction of secondary highway concrete pavement. Cement concrete foundation, high strength, and simple construction, but waterproofing and expansion joints need to be handled well. Asphalt concrete foundation, small shrinkage, crack resistance, excellent waterproof performance, modified asphalt has a high softening point and is not prone to oil backflow.
Requirements for foundation
It is recommended to use asphalt foundation for hybrid track, and the foundation should have certain strength and stability. There should be no cracks and uneven frost heave caused by freezing. In frozen areas, it is best to add a geotextile buffer layer between the asphalt layer and the gravel layer. The foundation along the water ditch should be specially waterproofed. The thickness of the asphalt layer is generally required to be 5 cm of coarse asphalt and 3 cm of fine asphalt. The flatness requires that the error of 3 meters is not more than 3 mm. The slope of the surface should be 6%0-10% from the outer edge of the runway to the inner edge (drainage ditch). It is recommended to achieve 8%0.
The compaction density of the foundation after rolling is >95%: the compaction density of the graded gravel layer of the roadbed is more than 2.3 kg/kg, the wheel track depth of heavy rolling is not more than 5MM, and the surface is flat and solid without sand pit plum blossom phenomenon. The density of the base gravel layer reaches more than 2.3 kg/kg, and the crushed gravel is more than 2.14 kg/kg. The surface is solid and smooth, the gaps are uniform, and there are no obvious traces of heavy rolling. The compaction density of the asphalt concrete black gravel layer reaches more than 97%, and the dry capacity reaches more than 2.35 kg/kg. There is no oil stain on the surface, no unmixed asphalt blocks, and it is flat and free of cracks.
Application Range
Mixed plastic tracks are generally used in professional competition venues and are a common type of track and field sport. The cost is much higher than that of breathable plastic tracks.

The hybrid plastic track is laid using a three-step construction method.
1. Check the asphalt foundation. If the surface gap of the asphalt foundation is relatively large, it must be treated with anti-seepage treatment before paving. The anti-seepage layer is made of the A and B components of the two-component hybrid track special paving material. Mix them evenly according to the specified proportion, and remember to add an appropriate amount of catalyst according to the temperature and temperature changes to form a hybrid track special paving composite material. Add an appropriate amount of quartz sand to it for scraping and sealing, and wait for it to solidify.
2. When the density and gap of the asphalt foundation meet the requirements, there is no need to make an anti-seepage layer or when the anti-seepage layer is completely solidified, add an appropriate amount of EPDM particles to the mixed composite material according to the specified proportion, and scrape it into an elastic layer with a thickness of 8-9 mm.
3. There are two methods for the anti-skid and wear-resistant surface layer: granule spreading and spraying: the granule spreading process is to scrape a 2 mm thick composite material on the elastic layer, and evenly sprinkle EPDM granules or PU granules manually. After curing, the excess EPDM granules that are not attached to the surface are swept away and finally a layer of reinforcing glue is sprayed on it; the spraying process is to add an appropriate amount of EPDM granules to the spray surface and stir evenly, and directly spray it on the elastic layer surface with special spraying equipment.
4. Use polyurethane marking paint to accurately measure the position of the process line according to the current track and field facility standards, and then spray it.
Self-tightening Plastic Track
Introduction to self-tightening plastic track
The new self-tightening particle-free plastic track is based on sports biomechanics and is designed strictly by national standards. The track is upgraded to a professional "three-layer composite" structure. It also designs a unique closed-cell micro-foam elastic interlayer to generate a steady stream of kinetic energy during exercise and better protect against injuries during exercise. It fully meets the latest impact absorption rate requirements of 35%-50% issued by the IAAF and is a domestically created on-site cast professional track structure.
The self-tightening track is an on-site casting paving process. After paving, there are no seams, no particles can fall off, and the flatness of the foundation is adjusted twice, making the track smoother, more beautiful, and more durable.
Scope of application
Used for international competition tracks, national competition venues, professional sports school training and teaching venues, ordinary school teaching venues, playgrounds, professional gymnasiums, and multi-functional stadiums.
Requirements for foundation
Measure the flatness and slope of the foundation on site. Take the straight and curved dividing line of the runway as the reference line, mark a point every 3 meters in the horizontal and vertical directions of the straight track, and use the center of the circle as the reference point for the curve. Use the theodolite to lay out the line every 5 degrees, mark a point every 3 meters, place a 3M ruler between any two adjacent points, and measure with a feeler gauge. The maximum local depression does not exceed 3MM for qualified points, >3MM for unqualified points, and the qualified rate of all measurement points reaches 85% for qualified, >94% for good, and >95% for excellent. Use a level to check the axis elevation and the elevation of each control reference point (relative) to see if they meet the requirements of the IAAF manual. The horizontal slope shall not be greater than 1%, and the longitudinal slope shall not be greater than 0.1%.
| Product features of self-tie plastic track |
| Excellent weather resistance: The unique anti-ultraviolet and anti-aging additives make the product have excellent anti-aging and anti-ultraviolet color change performance, and the color is bright and long-lasting. |
| Excellent wear and anti-skid performance: The more wear-resistant polyurethane surface layer formula is used to replace EPDM particles as the anti-skid layer. Special additives and diamond sand powder are added to the formula for spraying so that the surface layer forms a more anti-skid and wear-resistant concave and convex surface, which not only retains the traditional characteristics of polyurethane track materials such as weather resistance and aging resistance but also overcomes the old problem of easy threshing of traditional polyester track. |
| Excellent construction performance: Special mechanical spraying is used, the construction is simple, and the construction time can be greatly shortened. |
| After the EPDM particles are canceled, the project cost is cheaper. |
| The material is environmentally friendly and the quality is more stable. |
| Both cement foundations and asphalt foundations can be constructed. |
