  • Patent number: 4614686
    Abstract: A textured synthetic running surface and the like comprising a urethane elastomer base having thoroughly dispersed granular particles of urethane or rubber elastomers. Shredded particles of solid urethane or rubber of a nominal maximum dimension of from 0.062 to 0.125 inches are dispersed through the elastomer base and totally encapsulated thereby in concentrations of 26% to 32% by weight to provide a non-slip resilient running surface. The surface is applied by mixing two parts of liquid urethane elastomer in a mixing drum followed by mixing in of the granular particles in measured batches. The batched mixture is discharged from the mixing drum to a hopper which feeds the mixture by way of a pump to an application gun.
