Abstract:Precast concrete pavement (PCP) technology is gaining wider acceptance in the U.S. for rapid repair and rehabilitation of concrete pavements, as well as for reconstruction of heavily trafficked asphalt concrete intersections. Widespread use in the U.S. is fairly recent, with most projects in service less than about 10 years. PCP technology is being used for intermittent repairs (both full-depth repairs and full panel replacement) and for continuous applications (longer length/wider-area rehabilitation) with service life expectations of at least 20 years for repairs and at least 40 years for continuous applications, without significant future corrective treatment. Available PCPs include jointed PCP with reinforced or prestressed panels installed singly or in a continuous series. This guide set of checklists for the construction of PCP is intended for highway agency construction personnel. However, the checklists should be of use for the contractor personnel too. The checklists presented here follow the flow of typical PCP project construction activities. The checklists are not intended to replace the agency’s QA and the contractor’s QC activities, but rather to supplement and reinforce these activities to ensure a quality product is constructed. Agency and contractor personnel using the checklists should be knowledgeable in PCP construction and PCP technology. Depending on the type of PCP being used for a specific project and the project plans and specifications, not all the items in the checklists may be applicable. The user will need to determine which items are pertinent to their specific project.
