Abstract
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.
Claims15
A three dimensional member comprising:
- shredded tire particles having a size such that substantially 100% of said particles will pass through a three inch sieve and about 95% of said particles will be retained on a half inch sieve, and
- polyurethane attached to said tire particles to hold said tire particles together.
A process of forming a three dimensional support member to be located on a surface, said support member having a width, a length, and a thickness, said process comprising the steps of:
- mixing shredded tire particles and polyurethane together to allow said polyurethane to attach to said tire particles to hold said tire particles together,
- said tire particles having a size such that substantially 100% of said tire particles will pass through a three inch sieve and about 95% of said tire particles will be retained on a one-half inch sieve, and
- molding said tire particles and polyurethane to form said three dimensional support member.
Support structure comprising:
- a three dimensional support member located on a surface, and
- load bearing structure locate on said support member,
- said support member comprising:
- shredded tire particles having a size such that substantially 100% of said particles will pass through a three inch sieve and about 95% of said particles will be retained on a half inch sieve, and
- polyurethane attached to said tire particles to hold said tire particles together.
A process of forming a three dimensional member to be located on a surface, said member having a width, a length, and a thickness, said process comprising the steps of:
- mixing shredded tire particles and polyurethane together for a given time period and then mixing non-metallic fibers with said tire particles and said polyurethane for a time period shorter than said given time period to allow said polyurethane to attach to said tire particles to hold said tire particles together,
- said tire particles having a size such that substantially 100% of said tire particles will pass through a three inch sieve and about 95% of said tire particles will be retained on a one-half inch sieve, and
- molding said tire particles and polyurethane under pressure to form said three dimensional member.
