TRAFFIC PAINT PERFORMANCE IN ACCELERATED-WEAR TESTS

Accelerated-wear tetss of traffic paints on portland cement concrete and asphalt-concrete pavements are described. Installation and performance of several paints, including chlorinated rubber and chlorinated rubber-alkyd, alkyd, acrylic and alkyd-acrylic, epoxy, and water-based paints, are discussed. Durability and appearance ratings provided reliable indications of paint performance, but reflectivity ratings were extremely variable. Chlorinated rubber paint provided the best service life, but also had the longest drying time, averaging more than 3 min.
