Skid Resistance of Pavement Marking Materials: Volume I

摘要

The skid resistance of typical pavement marking materials is determined. A data base of full-scale locked-wheel skid resistance is presented for typical 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. In Volume I texture data are presented for field applications and for laboratory samples. Equations are developed for predicting skid resistance from texture measurements. The effects of glass beads, weathering, and polishing are examined in laboratory and field experiments. Based on a simulation, guidelines are developed for the maximum acceptable differential skid resistance between a pavement and the marking materials on it. Both two- and four-wheel vehicles are tested. Volume II of this report contains a complete listing of the data compiled in this project and is available in limited quantities to interested researchers. A summary of all the data which was utilized in the formation of the conclusions are included in tables of Volume I.
