National Center for Asphalt Technology










The National Center for Asphalt Technology (NCAT) was established at Auburnncat_building.gif University in 1986 with an endowment set up by the NAPA Research and Education Foundation. NAPA represents the HMA industry, thus providing strong ties between NCAT and industry. NCAT's mission: Improve HMA performance through research, education, and information services. NCAT welcomes inquiries and requests for information from those involved with the HMA industry.


NCAT researchers have improved aggregate testing and evaluation methods, developed mix design procedures for stone matrix asphalt, evaluated modified asphalt mixtures, improved mix design and control methods to minimize rutting, and developed a test to measure asphalt content without using solvents. Research project sponsors include the Federal Highway Administrative (FHWA), National Cooperative Highway Research Program (NCHRP), state departments of transportation, National Asphalt Pavement Association (NAPA), and NAPA Research and Education Foundation. The annual budget for all projects is $1.5M million to $4 million per year.


Much of NCAT's work is oriented toward problem solving for a technology transfer to HMA users. For example, on request, NCAT staff can quickly search the NCAT literature database for any asphalt technology topic and send the information to the individual requesting it. Much of the literature is in the NCAT library and can be used by industry.


The biannual newsletter, Asphalt Technology News, covers timely topics, includes questions/answers from industry personnel on topics they select, and has ready-to-use information. To receive the Asphalt Technology News, simply request it by calling 334-844-6228.
