RAP Pilot Study Reported in HMAT Magazine
NJDOT is constantly looking for ways to save resources. Using locally available materials for pavements in New Jersey decreases transport costs and fuel consumption. Add to that the possibility of incorporating more recycled materials into the pavements they use and it’s a win-win all around—less energy consumption, less aggregate and asphalt required, less material to dispose of, and cost savings to boot.
Currently NJDOT allows 15 percent reclaimed asphalt pavement (RAP) in wearing (surface) courses and up to 25 percent in intermediate and base courses. But there are concerns about durability and quality control of asphalt mixtures as RAP content increases.
In an effort to better understand the mechanical properties of pavements containing higher percentages of RAP, NJDOT asked CAIT’s Pavement Resource Program (PRP) to help them investigate the possibilities through a pilot project.
The results of the pilot project were recently published in Hot Mix Asphalt Technology (HMAT) magazine. The article was authored by Thomas Bennert, senior researcher for CAIT’s PRP, and Robert Sauber, P.E., and Eileen Sheehy, P.E., both from NJDOT’s Bureau of Materials.

CAIT Contributions on Bridge Project Receive NAPA Quality in Construction Award
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.
