Tools for using precast concrete pavement (PCP) systems to reduce the duration of construction closures on critical roadways.
Precast Concrete Pavement (R05) Implementation Assistance Webinars
Congestion and traffic delays due to roadway repair and rehabilitation are a major source of irritation for drivers. The duration and scheduling of work zones influences the exposure of both construction workers and drivers to traffic and related risk for accidents. A faster, safer, longer-lasting, and more efficient method for replacing or rehabilitating roadway surfaces is needed.
PCP systems are comprised of high-quality, prefabricated concrete panels that are formed offsite and installed during off-peak travel times. PCP is a versatile approach that can be used to rehabilitate roadways, toll plazas, intersections, bridge approach slabs, and tunnels – in addition to new roadway construction projects. PCP offers quality and durability similar to or better than traditional cast-in-place (CIP) concrete pavement. Cast in plants under ideal conditions, precast panels are subjected to higher quality control standards during the fabrication process, which results in a durable and ready-for-traffic road surface. The required smoothness typically is achieved by routine grinding of the panels soon after placement. Modular concrete panels that are installed onsite when the traffic volume is low reduce overall traffic congestion and provide a number of other advantages, such as pedestrian safety and avoidance of interrupted commerce.
The SHRP2 PCP Solution offers a series of guidelines and model specifications to help agencies effectively select projects for PCP, and to design, fabricate, and install long-life jointed and prestressed PCP systems. Further, the report recognizes that the cost of PCP panels has dropped significantly in the past decade. Coupled with shorter construction-related closures and potential long-life performance, PCP offers transportation agencies significant short- and long-term advantages.
