The Minnesota LRRB has produced a report, guidebook, technical summary, webinar, and presentation on this topic.
Gravel Road Management Tool (LRRB, 2019)
The Minnesota LRRB developed a spreadsheet tool to help local agencies manage their gravel road systems, such as tracking maintenance data, construction data, and costs. A User Guide (PDF) provides supplemental guidance.
Optimal RAP Content for Minnesota Gravel Roads
This report concluded that the optimal RAP content for unpaved road surfaces changes according to the properties of the materials used, testing methods, and site conditions.
Investigating the Necessity and Prioritizing Pavement Markings on Low-Volume Roads (MnDOT, 2018)
This project developed a prioritization approach and spreadsheet tool to assist local agencies in better understanding the value, cost, and need for markings along their roadways to make the best use of available budgets.
