• Abstract:
  The Texas Department of Transportation (TxDOT) initiated a review of their guardrail standards ; based on the outcome of recent crash test results and a Federal Highway Administration technical ; memorandum pertaining to guardrail height. TxDOT expressed interest in the use of a generic 31-inch tall ; guardrail to provide enhanced containment capacity for light trucks. However, some concerns were ; expressed regarding the increased size of the blockout used in the Midwest Guardrail System (MGS). ; Consequently, TxDOT requested an evaluation of a 31-inch tall guardrail system that incorporates ; conventional 8-inch deep offset blocks. ; The test reported herein corresponds to American Association of State Highway and Transportation ; Officials (AASHTO) Manual for Assessing Safety Hardware (MASH) test 3-10. This is primarily a severity ; test that assesses risk of injury to the vehicle occupants. This test was considered to be the more critical of ; the two tests due to the potential for increased vehicle-post interaction resulting from decreasing the depth of ; the offset blocks from 12 inches to 8 inches. The 31-inch W-beam guardrail with standard offset blocks met ; all required MASH performance criteria for test 3-10.
