Special Tech Transfer Webinar: Using Lamb Wave to Measure Pavement

Minnesota is pleased to be part of the National Road Research Alliance (NRRA)—a pooled fund that focuses on solving problems that impact road owners with an emphasis on customer needs. This pooled fund helps direct and compliment the use of the MnROAD test track for local, regional and national research, tech transfer and implementation needs. Road owner agencies provide input and participate in the decision making needed for MnROAD construction and research. MnDOT provided $2.5 million in construction funding to aid in the development of the next round of test sections at MnROAD to support common goals. Industry and academia also play an important role to provide critical input on long-term future trends in research and barriers to implementation, including working with their customers and members who play a direct role in implementation.Current NRRA Agency Members
