In recent years, many agencies have started investigating strategies for pavement rehabilitation and reconstruction that are faster and can produce longer lasting pavements. Expedient rehabilitation that results in a shorter pavement lifespan is no longer considered acceptable by most highway agencies. A promising alternative rehabilitation strategy is the effective use of modular pavement technologies, principally precast concrete pavement (PCP) systems, which provide for rapid repair and rehabilitation of pavements and also result in durable, longer-lasting pavements. Rapid construction techniques can significantly minimize the impact on the driving public, as lane closures and traffic congestion are kept to a minimum. Road user and worker safety is also improved by reducing road users’ and workers’ exposure to construction traffic. One of the projects funded under SHRP 2 is Project R05, Modular Pavement Technology. The objective of Project R05 project was to develop better guidance for use by highway agencies to implement the PCP technology. This report presents the findings from the Project R05 study and includes a review of the available PCP systems, a summary of applications to-date, and guidelines for design, fabrication, installation, and selection of PCP systems.
