National Road Research Alliance

Current NRRA Agency Members

The National Road Research Alliance (NRRA) is a Pooled Fund with a mandate to improve the future sustainability of our roads through research and a commitment to cooperative implementation. The alliance sponsors research at the MnROAD test track, one of the most sophisticated cold-weather pavement facilities in existence. Our alliance consists of state DOTs and other government roadway agencies, private companies, academic institutions, and associations. Together, we make the decisions for MnROAD construction and research.

Research Teams

Our research teams are divided into five main areas: Flexible, Geotechnical, Intelligent Construction, Preventive Maintenance, and Rigid. The Executive Committee is led by state agency members and guides the decision-making for the research to be funded.

Join the Alliance

To date, eight state agencies and more than 50 industries, associations, and academic institutions have become NRRA members. We are sharing expertise and are learning about new tools and methods to improve and expand transportation systems nationally. Our alliance is strong, but grows stronger with more participants. Join us and shape the future of our roads.
