Abstract

Questionnaires were sent to all the state highway departments containing over 70 items relating to the types of equipment used, methods of application, drying time of paint, use of glass spheres for night reflectance together with other pertinent aspects of pavement marking. Data analysis of questionnaires indicates a growing interest in marking traffic lines on pavements as a means of safety on highways. From 48 states reporting, 18 report that the stripers were designed and built in their own shops, 29 report that stripers were purchased from commercial sources and one state reports that their markings are placed by a contractor. Thirty states report using self-propelled units, nine trail the unit, eight use the pushmobile type. Forty- four states use pressure nozzles while four use the flow type. Thirty-eight states place preliminary markings for the equipment to follow. Thirty-seven states plus four provinces reporting from canada use reflectorized markings for increased night safety. Dash line length and spacing is according to quality of paint and application methods.
