IN-SERVICE EVALUATIONS OF EXPERIMENTAL TRAFFIC BARRIERS: AN INTERIM REPORT

The 1977 "AASHTO Guide for Selecting, Locating, and Designing Traffic Barriers" defines an experimental barrier as one "that has performed successfully in full-scale crash tests and promises satisfactory in-service performance." This report summarizes available information on several experimental barrier systems that have been recently installed throughout the country. Included are cost, construction, and performance data on the following experimental barriers: (1) Self-Restoring Barrier (SERB) Guardrail; (2) Service Level 1 (SL1) Bridge Rail; (3) Connecticut Impact Attenuation System (CIAS); (4) SENTRE Guardrail Terminal; (5) Colorado Type 3F Median Barrier End Treatment; (6) Two high-performance truck barriers (Idaho and Pennsylvania); (7) IBC Sand-Filled Median Barrier; and (8) Modified Thrie Beam Guardrail. The last two barriers are presently classified as operational by the Federal Highway Administration.
