FIELD TESTING OF TWO FAST-DRYING TRAFFIC PAINTS
Problems in achieving specified 60-sec drying times using newly adopted heated paint led to evaluation of a faster 20-sec drying time paint. In field tests it was compared with the regular New York 60-sec paint. Drying time was determined by driving an automobile over the fresh paint until no tracking occurred. Performance was evaluated using ASTM Method D 713 ("Conducting Road Service Tests on Traffic Paint"). It was determined that 1) the 20-sec paint essentially met the drying time requirements, 2) the 60-sec paint did not meet the drying time requirement under high temperature and humidity, 3) the 60-sec paint had slightly better serviceability than the 20-sec paint, and 4) bead retention may be a problem for both paints when conditions promote very fast drying. Retention may be improved by locating the bead dispenser closer to the paint spray nozzle. /FHWA/
