MnROAD Documentation and Data

Orange barrels on a highway


MnROAD test sections are routinely monitored to track the changes in pavement performance over time. Several types of measurements are made continually throughout cell life. Some measurements are made seasonally and others annually. Use the table below to access MnROAD data and the processes used to collect the data.

Current data collection schedule: Frequency of data collection (PDF).

MnROAD’s most recent data release (data release 1.0) allows researchers to access much of the data online and is also incorporated in the tables below. Due to the volume and complexity, some data (e.g. raw ride quality, pre-2008 FWD time history files, dynamic load data, etc.) is not included in the data release. This data is stored offline and available on request. If you don't see the data you're looking for please contact us.
