National Road Research Alliance

Current NRRA Agency Members

The National Road Research Alliance (NRRA) has 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, they make the decisions for MnROAD construction and research.

Our alliance is strong, but it would be stronger with your participation. Join us and shape the future of our roads.


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. Please visit the membership page for more information, or contact Glenn Engstrom or Ben Worel for questions.
