Guardrail-Bridge Rail Transition Designs, Volume I: Research Report

DTFH61-83-C-00028This project was concerned with the transition designs used between w-beam and the guardrail, and rigid bridge rail parapets or wingwalls. State designs submitted to the federal highway administration (FHWA) were rated and designs selected for crash test evaluation. New designs were also formulated and subjected to crash test evaluation. Most of the crash tests were conducted with 4500 lb (2000 kg) cars at 60 mph (95 km/h) and a 25 degree angle. Design drawings are presented along with recommendations for use of these transition designs. Guidelines for transition features are given and design procedures for independent end blocks are given

Bridge Rail Designs and Performance Standards, Volume I: Research Report

DTFH61-84-C-00002This project evaluated bridge railings. State bridge rail designs submitted to the Federal Highway Administration (FHWA) were rated and the best of each type were selected for crash test evaluation. When necessary, the designs were improved and retested. Most of the crash tests were conducted with 4500-lb (2025-kg) cars at 60 mph (95 km/h) and a 25-degree angle and 1800-lb (800-kg) cars at 60 mph (95 km/h) and a 20-degree angle. Performance standards proposed in 1986 are presented, along with bridge railing geometric design considerations to minimize vehicle snagging. Design drawings of the successfully tested bridge rails are included
