Updates & Features
PRP Director Wins Best Paper from TRB
Nov 2014 – Dr. Thomas Bennert, director of CAIT's Pavement Resource Program, was named winner of the K.B. Woods Award for outstanding paper by the Transportation Research Board (TRB). The paper covers environmentally sustainable strategies to incorporate higher percentages of recycled asphalt pavement (RAP) in new paving projects.
CAIT and NJAPA host 56th Annual New Jersey Asphalt Paving Conference
March 2013 – Over 400 asphalt paving professionals attended the annual conference to discuss paving challenges and innovative asphalt materials.
Rutgers Pavement Lab Gets AASHTO Stamp of Approval Eight Years Running
Febraury 2013 – AASHTO officially recognized the Rutgers Asphalt Pavement Laboratory as one of a few university-based AASHTO Materials Reference Laboratories. Under PRP director Tom Bennert, Ph.D., the lab staff completed a series of rigorous materials and standards tests to earn this prestigious distinction.
PRP Director, NJAPA, and NuStar Team Up for Article on Warm Mix
April 2012 – PRP Director Tom Bennert, Robert Sauber (NJAPA), and Frank Fee (NuStar) collaborated on an article published in this month's issue of Asphalt Pavement Magazine. The article covers an NJDOT project to improve safety and reduce noise on a deteriorating section of I-280 in Essex County, NJ. The researchers and contractor used a Warm Mix Asphalt in two stages of the rehabilitation: the thin overlay and a "top coat" open-graded friction course (OGFC).
PRP Lab Researcher Wins Industry Award
March 2012 – Kristen Derewecki, graduate student researcher for CAIT’s Pavement Resource Program, received the David R. Jones award from the Association of Modified Asphalt Producers (AMAP) in February.
Pavement Lab Front and Center in Statewide News
January 2012 – CAIT's Pavement Resource Program asphalt pavement lab was featured in the statewide newspaper, the Star-Ledger, with a story on page 1 of the New Jersey section. You can read the online version of the story on nj.com.
Bennert tapped for Better Roads article
Pavement Resource Program director and asphalt expert Dr. Thomas Bennert was interviewed for an article on recycled pavement in Equipment World's Better Roads. The article posed the question, "what percentage of RAP is right?" Excerpts from Bennert's TRB paper and presentation, Higher RAP Mixes in New Jersey: Changes in Mix Design and Production, were included in the article. (Nov 13, 2011)
PRP Recertified by AASHTO
CAIT’s Pavement Resource Program (PRP) received official word from the American Association of State Highway and Transportation Officials (AASHTO) in March 2011 that it had successfully been reaccredited as an AASHTO Materials Research Laboratory (AMRL).
PRP's Bennert Appointed to FHWA HMA Working Group
Thomas Bennert, program manager for CAIT’s Pavement Resource Program (PRP), was recently appointed to the FHWA Technical Working Group (TWG) on warm mix asphalt. The purpose of the group is to coordinate, develop, and improve national guidance and recommendations for the warm mix asphalt program. The group will provide feedback as well as encourage correct use of warm mix asphalt technologies and address construction problems with current state-of-the-practice solutions. Bennert attended a TWG meeting from December 14–17 in Seattle, Washington. (Nov 2009)
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. (July 2009)
