Western Research Institute

Western Research Institute is proud to be a research partner of the Federal Highway Administration, working to discover how the physical properties of highway materials contribute to their performance in the nation’s roadways.

Knowing your materials helps you know how they will perform over time.  WRI works to identify significant variables that affect the life-cycle performance of asphalts and pavement systems.  From our research on the fundamental properties of asphalts, aggregates, additives and interactions, we develop practical instruments and predictive tests used by government and industry. 

By providing the tools to distinguish long-term performance characteristics of highway materials, we help transportation officials get the best possible materials in the road. According to a National Research Council report, the SuperPave® specifications, based on research by WRI and others, have saved taxpayers up to $2.9 billion per year in reduced highway maintenance costs. 

We also put our know-how to work for asphalt, additives and roofing suppliers, trade associations and transportation agencies—anyone with a need for greater insight into asphalts and other transportation materials. We perform non-routine chemical and physical analyses of asphalt materials and conduct forensic and customized research for private and public clients.

WRI hosts the Petersen Asphalt Research Conference and the Pavement Performance Prediction Symposium, annual forums that introduce the latest findings from researchers throughout the industry and attract international participation from top asphalt professionals.

Let us put our know-how to work for you.
