The 2021 season of pavement testing has been completed. This year the testing team faced different difficulties than last year when COVID-19 delayed the start of the driving season. Multiple equipment issues sidelined driving for several weeks throughout the season. One county was not able to be driven because of the delays and they will be first on the list in 2022. The counties that have completed testing and have data are being processed and reports will be out as soon as possible.
For those that are new, PathWeb is a web-based application for viewing current road rating data and video logs. PathWeb is accessible right now for all county engineers and their staff from anywhere internet connection is available. GIS map integration will also display the distress levels from different color coding. Below are a few examples of what is visible on PathWeb. Counties are driven every two years. Counties to be surveyed in 2022 have been notified by Melissa Cole and the Pavement Management team at MnDOT.
