Guidelines and tools for the selection, design, construction, installation, and maintenance of precast concrete pavement systems, and tools for cost/ benefit assessment in situations where the technology may apply.
Modular pavement technology use is rising, but little guidance has been available to make the most of these systems. This research provides guidance transportation agencies can use to design, fabricate, construct, and maintain PCP systems that can speed up roadway reconstruction without sacrificing quality and to reopen lanes sooner.
The guidelines, included in the research report, are available at www.trb.org/Main/Blurbs/167788.aspx.   Model specifications are also available for download from that page.

Staff Responsibility: James Bryant
Over the last 10 years, several transportation agencies—including California DOT, Illinois Tollway Authority, New Jersey DOT, New York State DOT, and Utah DOT—have implemented precast concrete pavement (PCP) systems; and Delaware, Missouri, Michigan, and Hawaii have constructed demonstration projects. The production use of PCP technology in the United States, however, is of recent origin, and information on modular pavement practices and performance is not well documented. Lacking this information, many highway agencies and industry partners have not fully embraced the technology. 
The objective of this project was to develop tools for public agencies to use in the design, construction, installation, maintenance, and evaluation of modular pavement systems.  
The key tasks in this project included the identification of PCP systems in the United States and internationally; evaluation of PCP performance; development of guidelines for selection, design, fabrication, and installation of PCP systems; and development of model specifications. The following PCP applications were investigated: (1) intermittent repairs—for full-depth repairs or full slab replacement, generally used on jointed concrete pavements; and (2) continuous applications—for longer or larger pavement rehabilitation. As part of this project, field tests were performed at the sites of 16 PCP projects.
Products: Precast Concrete Pavement Technology, SHRP 2 Report S2-R05-RR-1, was published in June 2013.  It is available as an Adobe PDF.  A printed version is available through the TRB bookstore.  An e-book version of this report is available for purchase at Google, iTunes, and Amazon.  A fact sheet and project brief are also available.
