FHWA Project R05 IAP Funded Project Case Study: Florida I-10 Precast Concrete Bridge Approach Slab Demonstration Project

Repair and rehabilitation of the aging highway infrastructure continues to be a challenging endeavor for U.S. highway agencies. Thousands of miles of highway pavements and hundreds of bridge approach slabs need rehabilitation along highways that carry over 100,000 vehicles/day, including a large percentage of trucks. Extended lane closures on these highways must be avoided to prevent compounding congestion—which means rehabilitation work must be completed rapidly. While many projects have been completed using rapid-setting concrete, results have been inconsistent. Use of precast concrete (PC) panels have shown to be promising alternatives The production use of PC panels has come a long way since the first production project was constructed in New York State in 2001. 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, ramps, and intersections. PC panels are also being used to rehabilitate bridge approach slabs. Several U.S. highway agencies have implemented the PC panel technology, and other agencies have constructed demonstration projects. In the U.S., the PC panel technology is being used for intermittent repairs (full-depth joint repairs or full panel replacement) of concrete pavements and for continuous applications (longer length/wider area rehabilitation) of both asphalt and concrete pavements 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 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 application of PC technology to rehabilitate asphalt and concrete pavements. In 2013, the SHRP2 Implementation Assistance Program (IAP) was created to help highway agencies and metropolitan planning organizations deploy SHRP2-developed products to deliver more efficient, cost-effective solutions to meet the challenges facing transportation agencies. 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 Florida Department of Transportation, one of the agencies selected as a lead adopter of Project R05 technology, received an award of $300,000 to help offset the cost of constructing a PC project. This case study report provides details of the 2018 project that used PC panels for rehabilitation of the east-side bridge approach slab along westbound I-10 near Quincy, Florida.
