NRRA Research Pays Off | August 2025
Designing Safer Pavements: Frictional Resistance in Asphalt Mixture Design presented by Imad Abdallah, Ph.D., Director - Center for Transportation Infrastructure Systems (CTIS) and Associate Professor - Department of Civil Engineering, UTEP

While structural performance is essential, functional performance, particularly road user comfort and safety, is equally critical. Pavement distresses can significantly degrade ride quality, while surface friction, or skid resistance, plays a key role in ensuring safety. Despite decades of crash reduction initiatives by highway agencies, the incorporation of friction resistance considerations into the asphalt-mix-design process remains limited and warrants greater attention.
