Fhwa Project R05 Iap Funded Project Case Study New Britain Bus Pads Precase Concrete Pavement Demonstration Project

The production use of precast concrete pavement (PCP) has come a long way over the last 15 years. The technology is gaining wider acceptance in the U.S. for rapid repair and rehabilitation of concrete pavements as well as for heavily trafficked asphalt concrete pavements and intersections. Several U.S. highway agencies, including Caltrans, Illinois Tollway, and the New Jersey, New York, and Utah State Departments of Transportation, have implemented the PCP technology, and other agencies have constructed demonstration projects. In the U.S., the PCP technology is being used on concrete pavements for intermittent repairs (full-depth joint repairs or full panel replacement) and for continuous applications (longer length/wider area rehabilitation) with service life expectations of at least 20 years for intermittent repairs and at least 40 years for continuous applications, without significant future corrective treatment. The use of PCP on asphalt pavements includes the replacement of ramps, intersections and bus pads. The Strategic Highway Research Program 2 (SHRP2) Project R05 was conducted from 2008 to 2012 to develop technical information and guidelines that would encourage the rapid and successful adoption of PCP technology. In 2013, the SHRP2 Implementation Assistance Program (IAP) was created to help State DOTs, metropolitan planning organizations, and other interested organizations deploy SHRP2-developed products to deliver more efficient, costeffective solutions to meet the complex challenges facing transportation agencies. On March 28, 2014, the Federal Highway Administration—in partnership with the American Association of State Highway and Transportation Officials—announced the selection of several transportation agencies receiving implementation and technical assistance awards as part of round 3 of the SHRP2 IAP. The Texas Department of Transportation, one of the agencies selected as a lead adopter of Project R05 technology, received an award of 300,000 [dollars] to help offset the cost of constructing a PCP project. This case study report provides details of the 2016 PCP use for rehabilitation of a distressed asphalt concrete pavement at the intersection of Route 97 and Route 72 in McMullen/LaSalle County, Texas.

On March 28, 2014, as part of round 3 of the IAP, four lead adopters were selected to receive financial support from the Federal Highway Administration for implementation of PCP technology. Kansas Department of Transportation, one of the agencies selected as a lead adopter, received an award of 300,000 [dollars] to help offset the cost of the implementation of PCP technology in the State. This case study report provides details of the 2015 PCP use for rehabilitation of two distressed concrete pavement intersections and a bridge approach section along US 73 in Leavenworth, Kansas.

On August 7, 2015, the Federal Highway Administration—in partnership with the American Association of State Highway and Transportation Officials—announced the selection of 21 transportation agencies receiving implementation and technical assistance awards as part of Round 6 of the SHRP2 IAP. The Connecticut Department of Transportation, one of the agencies selected as a lead adopter of Project R05 technology, received an award of 150,000 [dollars] to help offset the cost of constructing a PCP project. Connecticut also received user-incentive funds, in the amount of 75,000 [dollars], for the development of plans, specifications, and estimates (PS&E) related technology transfer activities leading to agencywide adoption of PCP technology. This case study report provides details of the 2016 PCP use for rehabilitation of two distressed asphalt concrete bus pads along a section of the busway of CTfastrak, a bus rapid transit system in New Britain, Connecticut.

This evaluation assesses the outcomes of the Federal Highway Administration’s (FHWA’s) investment in precast concrete pavement (PCP). The evaluation team determined the benefits and costs of individual PCP projects and, where possible, extrapolated findings from the data based on overall themes. Additionally, the evaluation team determined the outcomes and impacts of FHWA research, demonstrations, workshops, and related activities and developed recommendations to facilitate the continued adoption of the technology. FHWA’s efforts were found to be largely successful and contributory to the development and adoption of PCP. FHWA has overseen initial research and prototypes and has helped the use of PCP technology become routine in some States. PCP is an effective and efficient way to conduct roadway maintenance, repairs, and reconstruction. Benefits significantly exceed costs in high-volume areas or unique roadway sections that would lead to significant detours if closed for long periods of time. PCP also allows for innovative maintenance practices and cost savings, such as the reuse of concrete panels for temporary repairs.
