MnROAD Data

MnROAD test sections are routinely monitored to track the changes in pavement performance over time. MnROAD’s most recent data collection processes and data can be accessed online and is also incorporated in the table below. Due to the volume and complexity, some data (e.g. raw ride quality, pre-2008 FWD time history files, dynamic load data, some sensor data, etc.) is not included in the data set. This data is stored offline and available on request. If you don't see the data you're looking for please contact us.
