MnROAD includes two test roadways, located along westbound I-94 between Albertville and Monticello, Minnesota. It is owned and operated by the Minnesota Department of Transportation in cooperation with its National Road Research (NRRA) partners. MnROAD test roadways have over 75 unique pavement test “cells” designed to investigate the performance of different pavement designs and materials and exposed to actual vehicles and Minnesota climate. Their performance is monitored by sensors within the road structure, as well as many non-destructive and surface tests, such as ride quality testing, deflection measurements (falling-weight deflectometer), and visual distress surveys. In addition to the two test roadways, several other test sections on other roadways are tracked and evaluated within the MnROAD system.
Here is how you can use this MnROAD data portal:
MnROAD data is presented by Section ID. Section ID is comprised of the cell the study is in, which lane the data applies to, and the start year of the Section ID. A new start year for a section ID is given when a layer is added or a new study begins. For example, data for the driving lane of cell 5 that received microsurfacing in 2012 is in Section ID 5-D-2012.
