摘要

The California Department of Transportation (Caltrans) has been using asphalt rubber (AR) seal coats as a pavement preservation strategy or an interlayer for pavement-rehabilitation projects since the 1970s. One type of seal coat is hot-applied chip seal, which includes placing a spray of hot asphalt binder followed by a layer of crushed stone. The aggregates are then rolled and embedded into the binder. The chip seals seal the existing pavement surface, extend its service life and provide a solid wearing course with good skid resistance.
