About Minnesota Road Research

"To improve the quality and value of the Minnesota roadway system while reducing future taxpayer costs by extending pavement life."

The Minnesota Road Research Project (MnROAD) is the world's largest and most comprehensive outdoor pavement laboratory, distinctive for its electronic sensor network embedded within six miles of test pavements. Located 40 miles northwest of Minneapolis/St. Paul, its design incorporates 4,572 electronic sensors. The sensor network and extensive data collection system provide opportunities to study how heavy commercial truck traffic and the annual freeze/thaw cycle affect pavement materials and designs.
