CAIT Contributions on Bridge Project Receive NAPA Quality in Construction Award
PRP News Archive, February 2009
A joint effort among CAIT’s Pavement Resource Program (PRP), A.E. Stone, and the New Jersey Department of Transportation (NJDOT) has received the National Asphalt Pavement Association’s (NAPA) prestigious 2008 Quality in Construction Award. The award recognizes exemplary quality and innovative hot mix asphalt paving throughout the United States.
The winning project—the Route 87 Absecon Inlet Bridge linking Brigantine Island and the mainland in Atlantic County, New Jersey—was completed by NJDOT in 2008. CAIT-PRP's contributions to the project included development of the mixture design, performance testing specification, and conducting the actual performance testing. Also playing a crucial role in the mix development and implementation were Robert Sauber and Eileen Sheehy of the NJDOT Materials Bureau and Robert Blight of the NJDOT Pavement Technologies Unit.
The project entailed resurfacing the aging bridge to prevent the further deterioration of the concrete deck. A newly approved bridge deck waterproofing surface pavement course will extend the life of the bridge. The mixture is the first of its kind to be approved and implemented in the United States.
While the mixture was designed primarily as a waterproofing surface, it also performed well in tests for rutting, road noise, and skid resistance. Design and testing of this material was conducted in CAIT’s Rutgers Asphalt Pavement Laboratory (RAPL), which is part of PRP, under direction of Thomas Bennert. The waterproof wearing surface is derived from an asphalt surface also developed by RAPL that is currently in use on the Port Authority of New York and New Jersey's George Washington Bridge. The combination of these elements as well as on-site quality control provided the Brigantine connection bridge with a quality road surface. The resurfacing project was accomplished in two days, met all performance criteria, and was completed with minimal impact to seasonal traffic.
The NAPA awards were held in San Diego during the association’s annual meeting in January 2009.
