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, 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.

To date, eight state agencies and more than 50 industries, associations, and academic institutions have become NRRA members.

Join us and shape the future of our roads.
