The Evaluation of Epoxy Thermoplastic Pavement Marking Material in Virginia: The Application: Interim Report

Report No: 84-R15

Published in 1983

About the report:

Epoxy Thermoplastic (ETP) is a recently developed epoxy-resin-based thermoplastic pavement marking material being promoted by the Federal Highway Administration as a possible substitute for conventional traffic paints and thermoplastics. Its reported advantages are excellent durability and adhesion, quick drying time, good visibility, lack of pollutants, and low cost. As part of its demonstration project program, the FHWA is field testing ETP in several states, including Virginia, in an effort to evaluate the performance of the material. The Virginia evaluation will compare the performance of a 5.8-mile section of ETP lane markings on Interstate 95 to that of a corresponding section of traffic paint on the same highway. The initial installation of the material in Virginia had several equipment and operational problems which resulted in varying thicknesses and distributions of beads along the ETP stripes. These problems and the resulting inconsistencies, as well as the properties of the ETP material and the layout of the Virginia installation, are discussed in this report.
