Investigation of Possible Maintenance Procedures for Insuring Best Performance and Service Life of Thermoplastic Traffic Stripes

摘要

Data is presented for three types of roads showing paint, thermoplastic compound, preformed plastic, and reflective pavement markers as adequate for maintaining existing thermoplastic lane and center lines. The first three are adequate for maintaining edge lines. Economic comparisons are given plus a list of certain other features which can be used in making a choice for maintenance use. The total service life and maintenance point are given. The maintenance point is found to occur when the night visibility drops to a certain rating.
