Summary

The purpose of the testing reported herein was to assess the performance of the Manual for Assessing Safety Hardware (MASH) TL-2 low-speed short radius guardrail treatment according to the safety performance evaluation guidelines included in American Association of State Highway and Transportation Officials MASH. The crash tests performed were in accordance with MASH TL-2. The Texas Department of Transportation low-speed short radius guardrail treatment performed acceptably for modified MASH Tests 2-33, 2-32, 2-31, 2-35, and 2-34.
