S & L Rubber Products

According to the ASTM definition, asphalt rubber (AR) is a blend of asphalt cement, reclaimed tire rubber, and certain additives in which the rubber component is at least 15 percent by weight of the total blend and has reacted in the hot asphalt cement sufficiently to cause swelling of the rubber particles. By definition, asphalt rubber is typically prepared using the wet process. The asphalt rubber is produced at elevated temperatures under high agitation to promote the physical interaction of the asphalt binder and rubber constituents, and to keep the rubber particles suspended in the blend.
