PAINTS AND GLASS BEADS USED FOR TRAFFIC DELINEATION MARKINGS

This investigation was designed to study the effectiveness of Missouri's traffic delineation system on both concrete and asphalt concrete surfaces and to determine if safe and economical improvements could be made. The investigation was organized into three phases so that elimination of variables could be accomplished with a minimum of samples. Phase 1, a field evaluation of the Missouri standard dispersion resin-varnish paint and a chlorinated rubber-alkyd paint in a transverse stripe, clearly indicated the superiority of the chlorinated rubber-alkyd paint to resist wear. Phase 2, a field evaluation of several proprietary high-heat paints in a transverse stripe, indicated a wide range of life expectancies to exist. Phase 3, a field evaluation of traffic delination stripes in the proper longitudinal configuration with various types of glass beads applied at 3, 4 and 5 lb/gal (360, 480, and 600 kg/cu m), showed the Missouri type 2 floating bead to consistently rank high in performance. This investigation has produced a superior delineation system that provides economic savings over the system previously used.
