Development of Improved Procedures for Removing Temporary Pavement Markings during Highway ConstructionAuthor/Presenter: Ellis, Ralph D.; Pyeon, Jae-Ho
During highway construction, temporary pavement markings are a common necessity as is their subsequent removal. Current methods to remove markings have often been unsatisfactory, leaving pavement scarring that can be mistaken for a line. The objective of this study was to develop a methodology for removing temporary pavement markings that would not adversely affect the pavement and would leave no trace of the marking. Two experimental methods, such as modified slurry-seal coat and modified sand-seal coat, were developed and tested. A modified sand-seal coat procedure was selected as the best method. Cost analysis to estimate the expense of the modified sand-seal application was performed. A draft specification for covering existing pavement markings with a sand-seal coat was developed as an optional method.
