    摘要: Pebble or granular based elastomeric surfacing materials that include an aliphatic thermoplastic polyurethane based pebble or granule bonded together with a two-part aliphatic polyurethane binder are provided. In one embodiment, an A side of the two-part binder has at least one polyol, and a B side of the two-part binder has multiple isocyanates. The multiple isocyanates can include for example hydrogenated methylene diphenyldisocyanate and hexamethylene diisocyanate. The A side and the B side of the binder are utilized to bond the pebbles together to form a surface that can be either porous or non-porous. In another embodiment, an A side of a two-part binder includes multiple polyols. The multiple polyols can include for example esterified ricinoleic acid polyols and caprolactone polyols. The A side of the two-part binder can be combined with a B side of the two-part binder and pebbles to form a non-porous surface. In yet another embodiment, a pebble-based surface is utilized as a wear layer in a multi-layer safety surface.
