ABSTRACT

Pavement rehabilitation in congested urban areas is a serious challenge for highway agencies because of construction-related traffic congestion and safety issues. Transportation agencies have investigated strategies for pavement rehabilitation and reconstruction that are faster but can still produce durable pavements. The use of modular pavement technologies, such as precast concrete pavement (PCP) systems, is gaining wider acceptance in recent years for rapid repair and rehabilitation of concrete pavements as well as for heavily trafficked asphalt concrete pavements and intersections. Under the SHRP 2 program, an extensive study on Precast Concrete Pavements was conducted. The SHRP2 PCP solution offers a series of guidelines and model specifications to help agencies effectively select projects for PCP, and to design, fabricate, and install long-life jointed and prestressed PCP systems. PCP systems consist of high-quality, prefabricated concrete panels that are formed offsite under controlled conditions and installed during off-peak travel times.
