Research

Over the past 20 years, NCAT researchers have advanced aggregate testing and evaluation methods, developed mix design procedures for stone matrix asphalt, evaluated modified asphalt mixtures, improved mix design and test procedures to minimize rutting, developed a perpetual pavement design method and developed the ignition method to measure asphalt content without solvents.

Current project sponsors include the Federal Highway Administration (FHWA), National Cooperative Highway Research Program (NCHRP), numerous state departments of transportation, NAPA and the NAPA Research and Education Foundation. NCAT's annual budget is typically about $5 million.
