Scope of application

Suitable for track and field competition venues at all levels—domestic and international—as well as training facilities. Also ideal for various school competitions and teaching venues.

Performance characteristics

1. Excellent weather resistance: Maintains high-quality performance under all weather conditions. 
2. Soft colors: Offers excellent visual effects and allows for a variety of color combinations, while also enhancing the aesthetic appeal of the environment. 
3. Excellent elasticity: Highly elastic, moderately hard, and long service life. 
4. Strong friction: Made by spraying a flexible, weather-resistant surface adhesive mixed with high-polymer-content rubber granules, enhancing wear resistance.

Construction technology

01. Runway Base Layer: The base typically consists of either a cement or asphalt foundation. For cement foundations, the cast-in-place thickness should be between 100 and 200 millimeters. After pouring, the curing period is approximately 28 days. The base’s moisture content must not exceed 8% before proceeding with the surface layer construction. Asphalt foundations generally have a thickness of 100 millimeters. After compaction, the curing period must last at least one week before the surface layer can be applied. Before applying the surface layer, the cement foundation must be thoroughly ground across its entire surface. After grinding, the surface must be thoroughly cleaned with water, allowed to dry completely, and then coated with a single-component penetrating primer. For asphalt foundations, construction can only proceed once the surface is completely free of moisture and dirt. 
02, Sealing Primer Layer: For cement-based surfaces, apply a single-component penetrating primer directly from the can after thoroughly mixing it. Roll the primer evenly over the entire surface. Only proceed to the next layer of work once the primer has completely dried and no longer sticks to your feet. For asphalt-based surfaces, use a single-component asphalt-specific sealing emulsion: mix 1 kg of emulsion with 2.5 kg of sand, 2.5 kg of cement, and 2.5 kg of water until thoroughly blended. Then, spread the mixture evenly over the entire surface using a large rubber rake until the asphalt surface is completely covered to a thickness of at least 1 mm. Only after the entire surface has fully dried can you proceed to the next stage of work. 
03. All-plastic PU sole adhesive layer: After mixing the two-component 1:5 PU with the runway-specific catalyst, proceed as follows: For one batch, combine 50 kg of PUB material with red pigment, 10 kg of PUA adhesive, 0.3 kg of runway-specific catalyst, and 1.5 kg of leveling agent. Thoroughly mix all ingredients until uniform. Then, apply the mixture using a thick-coating ruler and a large-toothed scraper. If the surface is uneven and has standing water, prepare another batch using the same proportions and use an aluminum alloy screed to level it. Only after the entire surface has completely dried can you proceed to the next step of construction. 
04. First layer of runway surface coating: After mixing the two-component 1:2 PU, surface spray particles, runway-specific catalyst, and leveling agent, use the following formulation: For each batch: 20 kg of red pigment for surface spray B material + 10 kg of adhesive for surface spray A material + 25 kg of surface spray particles + 0.15 kg of runway-specific catalyst + 1.5 kg of leveling agent. Thoroughly mix all ingredients together until uniform, then apply using a runway spraying machine, spraying across the entire surface in a back-and-forth pattern from left to right. Only after the entire surface has completely dried can you proceed to the next construction step. 
05. Second layer of runway surfacing: Similarly, after mixing the two-component 1:2 PU resin, surface granules, runway-specific catalyst, and leveling agent, use the following formulation: For one batch, combine 20 kg of red pigment for the surface coating (Component B), 10 kg of adhesive for the surface coating (Component A), 25 kg of surface granules, 0.15 kg of runway-specific catalyst, and 1.5 kg of leveling agent. Thoroughly mix all ingredients until uniform. Then, using a runway spraying machine, apply the coating across the entire surface in a reverse direction—moving backward from right to left, opposite to the direction used for the first coat. Only after the entire surface has completely dried can you proceed to the next layer of work. 
06. Runway marking layer: The runway marking paint is a proprietary oil-based marking paint developed by our company. After thoroughly mixing Components A and B at a 1:1 ratio, it can be applied using a runway marking machine or an air compressor for spraying.
