Precast Concrete Pavement Bedding Support Systems
Primary Topic: Pavement Base and Subbase
Description: The use of both jointed PCP and post-tensioned PCP systems has advanced during the last decade due to a combination of work sponsored by the Federal Highway Administration (FHWA), projects constructed by highway agencies, and innovations by the highway agencies and the construction industry. One area of innovation relates to improvements in the bedding support under precast concrete panels. This Tech Brief describes the technical considerations for bedding support and current bedding support practices for PCP systems.
