WET-PAVEMENT FRICTION OF PAVEMENT-MARKING MATERIALS
A total of 39 formulations of 11 types of marking materials were studied in the laboratory and in the field. Field skid number measurements were made at three sites by using the Pennsylvania Transportation Institute Pavement Friction Tester. Laboratory and field measurements were taken to determine British pendulum numbers, microtexture, macrotexture, and static coefficient of friction. Laboratory polishing and accelerated exposure testing were also performed. A wet-friction data bank for typical pavement-marking materials was established. Based on an analysis of these data, it was found that wet friction can vary dramatically for different marking materials. The texture of the underlying pavement affects the friction of thinner marking materials (paints), but the wet-friction resistance of the thicker marking materials is unaffected by the texture of the underlying pavement. Reductions in skid resistance from the paints can persist even after the aggregate surface is exposed from wear. The wet friction of marking materials exhibits a daily and seasonal variability much like that of the pavement itself, and the variability must be accounted for when skid-resistance measurements are made.
