MnROAD Data

 

MnROAD staff regularly monitor the Mainline, Low Volume Road and Farm Loop test sections to track the changes in pavement performance over time. Several types of measurements are made at certain intervals throughout the year and other tests are performed on an as-needed bases. ** PROPOSED SCHEDULE OF MONITERING ACTIVITES**

 

The MnROAD database includes field performance data, information about traffic loadings and laboratory material testing.** MnROAD Database GUIDE **

 

How To Get Data

 

Data Access

MnROAD is a state run public research facility allowing all of its data and reports to be available to anyone at no cost. Some data and reports are available online but direct access to the MnROAD database is limited to the key researchers at MnROAD.

 

This allows the MnROAD research experts to work with each data requestor to match the data that has been collected with the data needed for their study. MnROAD researchers are able to explain the exact methods and quality issues that might impact the potential use of the data requested. We request that researchers who use MnROAD data send us their research work plan. To request specific data from our MnROAD database please complete the data request form.

 

Data Collection Procedures

MnROAD collects and processes many types of data. Each type of data has its own method and frequency of collection. For further details on the methods used to collect each type of data Contact MnROAD.

 

The reports below document methods of current data collection:

 

 

Data Quality

Each set of data is collected, reviewed and entered into the MnROAD database system by designated research experts. Some data has automatic quality control checks before it is placed into the MnROAD database. The sensor tables are examples of the quality control range checks that separate data into either the (sensors type)_VALUES or the (sensor type)_ERRORS tables.
