A Comparative Performance Analysis of Pavement Marking Materials
This research provides the evaluation of the technical measurements of pavement marking materials from a two-year data collection on 2002 National Transportation Product Evaluation Program (NTPEP)'s Mississippi Test Deck from June, 2002 to June 2004. The materials studied in this research were divided into permanent and temporary material groups on two different pavement surfaces -- asphalt and concrete. The retro reflectivity and durability of permanent marking materials among different surfaces, colors and groups were studied. Also the characteristics for temporary tapes, which include internal tape strength, adhesion, tackiness and dicernablity were compared and regressed. This correlation analysis is to see whether these ratings are correlated to each other. The results of this study can be used for estimating service lives of pavement marking materials. They also can be used by states to select appropriate pavement marking materials for different needs.

Comparative Performance Analysis of Thermoplastic and High-build Pavement Markings
Performance data was collected and analyzed for the following pavement marking materials: Waterborne High-Build Paints, Forty (40) mil High-Binder Thermoplastics, and Ninety (90) mil Thermoplastics for life expectancy, application procedures, and governing policies. The data was obtained from the National Transportation Product Evaluation Program (NTPEP), a nationally accredited program that test pavement marking materials. Several key controlling measures used in the data collection include in-situ data from the same geographical location experiencing the same type of weather conditions, annual average daily traffic (AADT), and whether or not the materials were installed at the same time. This research will assist the Maryland Department of Transportation in selecting pavement marking materials for application throughout Maryland's highway infrastructure. -- Abstract.
