Abstract:
The production use of precast concrete pavement (PCP) has come a long way over the last 15 years. Since the first new-generation PCP projects were constructed during 2001, the technology has gained wider acceptance in the United States for rapid repair and rehabilitation of concrete pavements, as well as for heavily trafficked asphalt concrete pavements and intersections. Since 2001, many projects have been constructed and many advances have been made and continue to be made in the design, panel fabrication, and panel installation aspects of the technology. In the United States, the PCP technology is being used for intermittent repairs (full-depth or 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. The two sessions, organized by ACI Committee 325, with support from the Federal Highway Administration (FHWA), will present the current developments and best practices related to PCP design, panel fabrication, and panel installation processes. In the first session, experts from several highway agencies, including Wisconsin DOT, will present the implementation details related to new PCP applications by their agencies.
