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.
