Pavement Marking Materials: A Summary of New York State Research
This report summarizes pavement marking materials research conducted by New York from 1960 through 1975. Work concentrated on three general classes of marking materials -- traffic paints reflectorized with glass beads, raised reflective markers, and alternative pavement markings including thermoplastics. Many paint families and formulations were investigated in several pavement test installations. Modified alkyds with and without chlorinated-rubber provided the best service, with modified alkyds generally the most cost-effective. While raised reflective markings have shown promise for wet-night delineation, several problems have prevented their widespread use. The metal castings are subject to damage by carbide-tipped snowplow blades, and damage the blades. Based on this research, New York's standard pavement marking material (adopted in 1973) is a hot-applied modified-alkyd traffic paint with a specified drying time of 20 seconds, reflectorized with glass beads having a refraction index of 1.50 to 1.65.
