International Partnering for Asphalt Technology

Over the past year, the Federal Highway Administration's (FHWA) Fundamental Properties and Advanced Models Expert Task Group (ETG) has partnered with the International Union of Laboratories and Experts in Construction Materials and Systems (RILEM) to foster international collaboration on asphalt technology. The ETG was formed in 2005 to meet emerging challenges following the conclusion of work by previous ETGs on Superpave implementation. In October 2006, the ETG and RILEM held overlapping meetings at the University of Illinois at Urbana-Champaign. "The collaboration allowed for an international exchange on numerous aspects of asphalt pavement technology," said ETG secretary Katherine Petros of FHWA.

The RILEM meeting included discussions on advanced testing of bituminous materials and models to address cracking in asphalt pavements, while the ETG meeting featured discussion on the draft National Asphalt Pavement Roadmap. The roadmap presents a vision for future research and technology in asphalt pavement and material technologies. It was developed by the National Asphalt Pavement Association; FHWA; the American Association of State Highway and Transportation Officials; National Stone, Sand, and Gravel Association; and the Asphalt Institute.

To increase future collaboration with RILEM, FHWA will be joining as a corporate member and plans to participate in the October 2007 meetings of two of its asphalt technical committees. "FHWA should greatly benefit from the peer exchange on cutting edge research that RILEM offers," says Petros. FHWA is also cosponsoring RILEM's next conference on cracking, to be held in June 2008 in Chicago, Illinois.
