Precast Concrete Pavement Systems (PCPS) are being used around the nation as an alternative pavement treatment for repair, rehabilitation, and new construction of PCC Pavements. PCPS is best suited for time-restricted work zone access and night-time work. The process includes removing the existing distressed PCC panels, preparing the sub-base, and placing the Precast Concrete Paving Slab. This slab is then under-sealed and is either post-tensioned (pre-stressed post-tensioned system) or grouted (jointed system) and ready for traffic in as short as 5 hours. Both the pre-stressed post-tensioned and jointed systems will be featured in this Showcase. This type of approach helps to accelerate construction sequencing of the project, reduce work zone size while maintaining traffic on adjoining lanes using temporary lane closures, and greatly reduce travel impacts to motorists.
This Showcase featured speakers from various disciplines associated with this PCPS project on I-66 and Route 50 in Fairfax, VA. Topics ranged from VDOT's process of choosing PCPS to the Contrator's perspective on this project and the use of Precast Concrete Paving Systems on their jobs.
in addition to the presentations, night-time visit to the project site to view the construction took place as part of this Showcase.
