Surface Preparation of Pavements Prior to Application of Pavement Markings

摘要

This project was undertaken to demonstrate that surface preparation of pavements by wire brushing prior to application of traffic marking paint would result in extended service life of traffic marking paint. A brush assembly was designed, fabricated and installed on a Texas Department of Highways and Public Transportation striping truck and run over a variety of roads. It was found that brushing did not significantly extend the service life of the traffic marking paint. There was not sufficient improvement to consider mounting brush assemblies ahead of the spray guns on striping trucks for use on a daily basis.
