This report summarizes the results of data collected as part of the 1995 field and laboratory evaluations of pavement marking materials for the National Transportation Product Evaluation Program (NTPEP). The purpose of the NTPEP is to pool the professional and physical resources of the individual participating AASHTO member departments and to focus those resources to test materials of common interest in order to improve cost-effectiveness.

The type of testing performed under the NTPEP provides information that will be used to evaluate the acceptability of materials and to compare the performance of similar materials. The NTPEP also provides industry with a central focal point to initiate the process of supplying materials to many organizations through one sample submission rather than separate samples of the same material to each organization. The NTPEP does not accept or reject material, but rather, provides test results for evaluation.
