Support member formed of recycled material and process of manufacture |
摘要 |
A resilient support member is provided for supporting a sidewalk, road surface, etc. The support member is formed of tire particles and a polyurethane binder. The tire particles have a size such that 100% of the particles will pass through a three inch sieve and about 95% of the particles will be retained on a half-inch sieve. The tire particles form about 80% to 95% by weight of the support member and the polyurethane forms about 5% to 20% by weight of the support member.
