This report summarizes the results of data collected as part of the field and laboratory evaluations of pavement marking materials for the SASHTO Regional Test Facility. The purpose of the Regional Test Facility (RTF) is to minimize the amount of field and laboratory research testing of specific types of materials. This is accomplished by combining efforts in an organized manner to reduce the monetary and man-hour requirements of both the states and industry. A RTF for the twelve SASHTO states was approved at the 1988 SASHTO convention. The twelve SASHTO states are Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, South Carolina, Tennessee, Virginia, and West Virginia. The SASHTO Regional Test Facility (SRTF) began operation in November 1988 when informational packets were mailed to all known manufacturers of four types of material. One type of material was classified as striping materials. The manufacturers had until 5:00 p.m. at the end of the first working day in January 1989 to submit a Product Evaluation Form, a check for the testing fee, sample materials, and other pertinent information to the coordinator of the SRTF in order to have their product considered for inclusion in the testing process for that calendar year. A testing fee of $2,000 per sample was established for the striping materials. This fee covered the cost of performing the required field and laboratory tests and reporting the results. |
