Improving Pavement Marking Performance on Challenging Pavement Surface

Status:  Complete
Report Date:  10/21/2011


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.
