Abstract:Pavement markings need to be restriped from time to time to maintain retroreflectivity.
Knowing which material provides the most economically efficient solution is important.
Currently, no agreed upon method by which to evaluate the use of alternative pavement
marking materials exists. This study developed a methodology that measures the benefit of
pavement marking materials based on the public perceived benefit of retroreflectivity. Using
the measured benefit along with the cost of installation and impact on road users during the
installation process, a benefit/cost analysis was applied to evaluate different marking
materials used on Louisiana interstate freeways, including thermoplastics (both 40 mil and 90
mil), tape, and inverted profile pavement markings.
