What is the construction method of plastic runway?

1. The printed non-slip plastic runway needs waterproof treatment of cement foundation or back cover treatment of asphalt foundation first. After the grass-roots treatment and maintenance for 24 hours, the bottom of the runway can be laid. According to the national standard, 25% highly elastic black rubber particles with a particle size of 3-4mm are added to the plastic base, which are poured into the site after being evenly stirred, leveled, paved with a thickness of 10mm and maintained for 24 hours. Pour 2.5 mm thick printed track surface material into the whole site, scrape it flat with a rake, cover the material with a printing mold, and lift the printing mold 24 hours later to see the printed surface with 2-3 mm thickness. Special pattern design, wear-resistant and anti-slip, integrated surface layer, uniform thickness, no particles, no foaming, aging resistance, bright colors, and the best paving of asphalt base.

2. The cement foundation of mixed particle plastic runway needs waterproof treatment, and the asphalt foundation needs back sealing treatment. After the grass-roots treatment and maintenance for 24 hours, the bottom of the runway can be laid. According to the national standard, the runway base is mixed with 25% high-elastic black rubber particles with a particle size of 3-4mm, which are poured into the site after being evenly stirred, scraped and maintained for 24 hours. Pour 2mm thick runway surface material into the whole site, scrape it flat, and evenly sprinkle 3-5mmEPDM anti-skid particles on the whole site. After 24 hours, clean up the unbound EPDM particles, and then roll coat or spray a layer of runway-specific topcoat. Super nail resistance, suitable for all kinds of competition venues, easy to maintain, economical, strong impact absorption, aging resistance and bright colors. Paving on asphalt foundation is the best. ?

3. Check the foundation flatness of the composite particle plastic runway. The flatness measured with a 3m ruler should be within 3mm, and the whole stadium should be smooth. Mix high-elastic black colloidal particles with a particle size of 3-4mm with high-strength one-component adhesive, stir evenly, pour into a paver, spread with a thickness of 9mm, and maintain for 24 hours. The back cover of black rubber particles is made of PU glue mixed with 30% black rubber powder or talcum powder, and the back cover is kept for 24 hours. Pour 2mm thick pavement material into the whole site, scrape it flat, and evenly sprinkle 3-5mmEPDM anti-skid particles on the whole site. After 24 hours, clean the unbonded EPDM particles, and then roll coat or spray a layer of runway special topcoat. Anti-ultraviolet, effectively avoid sports injuries, with strong elastic layer and buffer layer, resistant to nail shoe wear, moderate hardness and good wear resistance. It is best to lay it on a reinforced concrete foundation.
