Richard Willis joined NCAT in January 2009 as a Post-Doctoral Fellow. He received a BS in physical science from Freed-Hardeman University in 2003 and a BCE from Auburn University in 2004. In 2005, he graduated with a master's degree in Civil Engineering from Auburn University. Dr. Willis has been involved in several studies at the NCAT Pavement Test Track. He is currently developing relationships between laboratory performance testing data and field performance measurements for flow number and the bending beam fatigue test. He is also beginning to study how warm-mix asphalt influences pavement performance in the field when coupled with high percentages of reclaimed asphalt pavement (RAP). He has served as a member of the Federal Highway Administration’s Asphalt Recycling Expert Task Group, and currently is a member of the Federal Highway Administration’s Sustainable Pavements Technical Working Group. He regularly conducts workshops on effectively using recycled materials in asphalt mixtures, and currently is the principal investigator on National Cooperative Highway Research Program Project 9-55, Recycled Asphalt Shingles in Asphalt Mixtures with Warm Mix Asphalt Technologies.
