PREDICTION AND SIGNIFICANCE OF WET SKID RESISTANCE OF PAVEMENT MARKING MATERIALS

A data base of full-scale locked-wheel skid resistance is presented for typical marking materials, including traffic paints of various formulations, hot spray and extruded thermoplastics, cold preformed plastics, temporary tapes, and some two-part systems. A variety of pavement surface types, including dense- and open-graded asphalt and portland cement concrete, are used in the study. British pendulum numbers and macrotexture profile data are presented for field applications and for laboratory samples of marking materials. Equations are developed for predicting skid resistance from these data. The effects of glass beads, weathering, and polishing are examined in laboratory and field experiments. In all cases, the skid resistance of the marking materials is less than that of the pavement to which they are applied. From the results of a simulation study, a description is given of the effects of differential pavement friction on the handling and stability of four-wheeled vehicles and single-track vehicles. A tentative procedure for setting minimum acceptable levels of marking material skid resistance for four-wheeled vehicle operation is developed from the simulation results. A procedure for setting minimum levels of skid resistance for single-track vehicle operation could not be established. An alternative approach to the problem is suggested. (Author)
