TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 306: Long-Term Pavement Marking Practices documents the current and best practices for managing pavement marking systems, identifies future needs, and addresses driver needs and methods of communicating information to drivers, selection criteria (e.g., reflectivity, pavement service life, wet weather performance), materials (e.g., color, durability, cost), specifications, construction practices, inventory management systems, and more.

This report details the first year of a two-year project. During the first year the emphasis was on determining the wet-night visibility of various pavement marking systems under a variety of realistic rainfall levels. The researchers performed a literature review. They analyzed 20 years of Texas rainfall data to determine the most appropriate rainfall levels to use as design criteria for a rain tunnel. Using a low, medium, and high rainfall rate (0.28, 0.52, and 0.87 in. per hour, respectively), a 1600 ft long rain tunnel was designed and built at Texas A & M University's Riverside Campus. Experimental subjects drove through the rain tunnel and looked for pavement markings simulating skip lines. The researchers rotated pavement marking samples at different locations before each trial. The detection distance was recorded when the subject located the pavement marking sample. The data were analyzed in four main sections: waterborne paints, thermoplastics, tapes, and exotic materials. The analysis also included investigations into the wet-night visibility of rumble stripes, as well as wider lines. The measured dry and wet retroreflectivity measurements were analyzed, and the predictive capabilities of the wet retroreflectivity measurements were evaluated with respect to the wet-night detection distance of the markings.

Waterborne paints are used to paint pavement markings (edgelines and centerlines) to provide guidance for motorists. The painted markings need to be repainted periodically as their retro-reflectivity deteriorates. The Indiana Department of Transportation (INDOT) repaints pavement markings at least annually. INDOT engineers would like to determine the feasibility of extending the time intervals of repainting pavement markings on at least some types of roadways. The purpose of this synthesis study is to accomplish the following: (1) to locate and assemble documented information on pavement marking durability; (2) to learn what criteria have been used in other states in measuring retro-reflectivity and scheduling pavement marking painting; (3) to determine the necessity of conducting full scale study on INDOT pavement markings; (4) to identify the type and cost of equipment required for retro-reflectivity measurements and conditions of operation of the equipment; (5) to organize, evaluate, and document the useful information that is acquired; and (6) to provide recommendations based on the evaluated information. This report presents the findings of the synthesis study on various pavement marking materials. It was found in this study that many state highway agencies have evaluated several types of pavement marking materials. The evaluation results include performance, cost, service life, and retro-reflectivity measuring equipment of marking materials. However, the results could vary from different sates. The information gathered through this study will provide INDOT engineers the state-of-practice of pavement marking materials in this country.

This report contains the Phase II effort on wet-night pavement markings, a benefit-cost analysis, and a study of contrast markings. Phase II effort consisted of expanding the study design from Phase I to include additional wet-night pavement marking products, the effects of glare and dry pavement on detection distances, and a benefit-cost analysis with respect to the use of different pavement marking systems to accommodate drivers under wet-night conditions.

Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF Innovation Center. This report summarizes the results of detailed evaluations performed on four handheld and two mobile pavement marking retroreflectometers. The evaluations were designed to test the measurement bias, repeatability, and reproducibility of handheld and mobile retroreflectometers produced by several manufacturers.
