Specialized Hybrid Surface Layer for Extreme Temperature Difference Regions

High temperature anti-slip: the upper layer material is added with anti-slip additives, which can maintain the friction coefficient even when the surface temperature exceeds 50℃ in summer, so as to avoid athletes from slipping; at the same time, the pore structure of the material can drain water quickly, preventing water accumulation from exacerbating the softening problem under high temperature.

PRODUCT INTRODUCTION

Typical structure (bottom-up)

Layering	Thickness	Material and foundation
The base layer	-	Concrete (≥150mm) or asphalt concrete (≥80mm), which should be flat, compact and slope less than 0.8%.
Waterproof primer	filter bed	High penetration polyurethane primer, closed the basic pores, enhance the adhesion, prevent dampness
An elastic floor	9-10 mm	Core layer: polyurethane glue + waste tire particles/EPDM particles * mixed laying, providing the main elasticity and shock absorption.
reinforcing plies	1-2 mm	Polyurethane glue + fine particles (optional) to fill the pores of the underlying layer and improve the flatness.
wear-resistant coat,scuff-resistant coating	2-3 mm	Two-component polyurethane topcoat + EPDM colored particles, sprayed to form a non-slip, weatherproof and uv resistant surface.
The stripline	0.5 mm	White polyurethane special marking paint, in line with the athletics track standards.

Product features and applications

All-weather use, strong weather resistance (-30℃~80℃), anti-ultraviolet, ozone resistant, can be quickly restored after rain.

Low temperature frost resistance: the underlying material has low temperature toughness (such as rubber particles with antifreeze agent), which can still maintain elasticity below-30℃, reducing the risk of cracking when freezing, and the surface texture design can enhance the grip in snowy weather

The core advantage of hybrid sports surface layer in extreme temperature difference areas is to balance the performance shortcomings under high temperature and low temperature through material combination and structural design, and achieve the goal of "deformation resistance, weather resistance and easy maintenance", which is especially suitable for airport runways, sports venues in high altitude areas, outdoor sports fields in cold/b tropical regions and other scenes.
