Effective Pavement Marking Materials and Applications for Portland Cement Concrete Roadways (4150-2)

This report describes the tasks of a study conducted to identify effective pavement marking materials and application procedures on Portland cement concrete (PCC) roadways in Texas. The researchers reviewed relevant literature, reviewed data from the National Transportation Product Evaluation Program (NTPEP), surveyed state departments of transportation, surveyed material manufacturers, and analyzed cost-effectiveness of various materials. Based on findings from the research tasks, the researchers generated a number of recommendations for pavement markings on PCC roadways in Texas, which include: o Use epoxy materials for long-term applications under the majority of traffic conditions, o Use preformed tape for long-term applications under very heavy traffic, and o Use TxDOT specification thermoplastic only for short-term applications with low to medium traffic.
