Precast Concrete Pavements (PCP) can be used as an accelerated rehabilitation technique for concrete pavements. The goals of this research study was to develop a PCP system approval process for potential implementation by state Departments of Transportation (DOTs) using current PCP specifications and practices. For this, a survey was conducted among 18 states regarding their specifications that are used for PCP and their approval processes for implementation of PCP. Based on the survey conducted, eight state specifications have been developed for PCP. Each specification focuses on four major PCP components: (i) dimensional and strength requirements, (ii) base stabilization materials, (iii) panel placement and alignment, and (iv) encasement grout materials. Based on the specifications and recommendations of state DOTs, a general approval process was developed for PCP systems. The generalized approval process included verification of PCP (i) material properties and precast plant capabilities and (ii) historical performance. The approval process outlines three different tracks in which the PCP contractor can describe past performance (ranging from low to high risk for state DOTs). Overall, this study provides state DOT agencies the necessary specifications and general approval process to improve and accept PCP systems as a pavement rehabilitation technique.
