Evaluation of Wet-Weather and Contrast Pavement Marking Materials and Applications

Project Description

Pavement markings are considered by many to be the most valuable and important means of communicating roadway information to the driver. Longitudinal pavement markings provide a continuous stream of information about the roadway that cannot be provided by signs or signals. Over the past decade, many pavement marking materials and/or applications have been developed that are marketed as providing improved visibility under conditions of wet-weather or poor marking/pavement-surface contrast. The Texas Department of Transportation (TxDOT) and other agencies have experimented with many of these materials/applications, but there exists little formal documentation of quantifiable benefits or conditions; i.e., pavement, weather, etc., where these benefits are most likely to occur. This research focused on the development of guidelines that can be used to select the most appropriate pavement markings application for wet-night conditions and light-colored pavement surfaces. The results were based on the results of visibility studies, material durability, costs, and installation and maintenance ease.
