The purpose of the testing reported herein was to assess the performance of the Texas Department of Transportation (TxDOT) W-beam guardrail with 71⁄2-inch diameter round wood posts in concrete mow strip according to the safety-performance evaluation guidelines included in the American Association of Safety Highway and Transportation Officials Manual for Assessing Safety Hardware (MASH) for Test Level Three (TL-3) longitudinal barriers. The crash test performed was in accordance with MASH Test 3-11, which involves a 2270P vehicle impacting the TxDOT W-beam guardrail with 71⁄2-inch diameter round wood posts in concrete mow strip at a target impact speed and impact angle of 62 mi/h and 25°, respectively. The TxDOT W-beam guardrail with 71⁄2-inch diameter round wood posts in concrete mow strip performed acceptably for MASH Test 3-11.

The purpose of the testing reported herein was to assess the performance of the Modified TxDOT Round Wood Post Guardrail System in soil according to the safety-performance evaluation guidelines included in American Association of State Highway and Transportation Officials' Manual for Assessing Safety Hardware (MASH) for Test Level Three. The modification involved reducing the guardrail post embedment depth from 40 inches to 36 inches to reduce the soil resistance and decrease the force required to deflect the post through the soil. The crash test performed was in accordance with MASH Test 3-11 criteria, which involves a 2270P pickup truck impacting the barrier at a target impact speed and angle of 62 mi/h and mi/h and 25°, respectively. The Modified TxDOT Round Wood Post Guardrail System in soil successfully contained and redirected the pickup truck. The barrier performed acceptably for MASHTest 3-11. The maximum dynamic deflection and permanent deformatin were 44.1 inches and 37.0 inches respectively.

This synthesis will be of interest to state department of transportation (DOT) roadway design, traffic, structural, maintenance, and research engineers and others concerned with highway safety issues. This synthesis describes the current state of the practice for the use of guardrails and median barriers and their crashworthiness. It includes information about the crashworthiness and typical applications of the most common, permanently installed, nonproprietary guardrail and median barrier systems used in the United States today. A significant amount of detail is included in the text to aid the design, selection, and locating processes for safe and effective guardrails and median barriers. The report presents data obtained from a review of the literature and a survey of state DOTs. The synthesis presents a description of the typical longitudinal barriers in use today, including drawings, the extent of their use, and the most recent testing on each guardrail and barrier system, with particular emphasis on NCHRP Report 230 and 350 requirements. In addition, it discusses the maintenance issues, cost constraints, and common problems with each type of barrier. The synthesis only discusses the crashworthiness of guardrails and median barriers; their transitions and terminals are not discussed.

This report documents the results of a crash test of a strong wood post thrie beam guardrail with a 2000-kg pickup truck impacting at a nominal speed and angle of 100 km/h and 25 degrees. This is the strength test for Test Level Three (TL-3) in NCHRP Report 350. It was found that the test results met all of the evaluation criteria. The pickup truck was smoothly redirected and remained upright.
