The inside of the runway safety area of ??not less than 1 meter Zhejiang Stadium plastic runway construction, the outside is also preferably one meter safety zone, starting area at least 3 meters, at least 17 meters sprint buffer segment. Shall not exceed the maximum inclination of the runway about 1: 1000, a downward gradient in the direction of running shall not exceed 1: 1000. Results from a bottom groove track: Polyurethane Mixture black rubber. The second intermediate layer: knot pattern - pulp from Zhejiang Stadium plastic runway construction, paving the formation of microbubbles obturator dissection Zhejiang plastic runway stadium construction, its elasticity, hardness, friction, slowing the pace of both the ground and always impact on human legs each joint impact, but also make the body get again and again continue to move forward momentum. IAAF newly issued standards with shock-absorbing rate requirement of 35% to 50%. Since knot knot grain pattern runway pictures from the runway picture three layers: from the junction flower pattern pulp, it is pure glue (flower syrup) plus diamond powder and promoting change agent stirring, professional machines spray up, after several hours of reaction, its own natural form of pure polyurethane glue material, non-slip surface.
