WRI is a leader in developing methods to understand how the phyiscal properties of asphalt affect performance over time. We have made substantial contributions to the SuperPave specifications to optimize highway service life and cost effectiveness.
WRI performs specialized research and consulting to identify the causes of problems with asphalts, additives or asphalt-aggregate combinations or other unexplained road failures. We perform non-routine chemical and physical analyses of asphalt materials.
