Improving Pavement Marking Performance on Challenging Pavement Surface Status: CompleteReport Date: 10/21/2011 Summary: Researchers documented the practices of MnDOT districts and other state departments of transportation in the use of pavement markings on challenging pavement surfaces, including those with seal coat and micro-surface treatments. Results showed that agency strategies for pavement markings on these surfaces typically involve using latex paint immediately after maintenance treatments, restriping with all-weather paint after two weeks and restriping with epoxy after one to two years.
