Abstract:

The Texas Department of Transportation desires to flare the ends of its freestanding single-slope concrete barrier system so the system can be terminated outside the clear zone. Currently, limited guidance exists on the acceptable flare rate for the single-slope portable concrete barrier under the American Association of State Highway and Transportation Officials (AASHTO) Manual for Assessing Safety Hardware (MASH) 2016 guidelines. This project evaluated flare rates for portable, freestanding, single-slope concrete barriers through finite element impact simulations and full-scale crash testing. This report presents details of the simulation work and the full-scale crash testing performed under the project. The purpose of the tests reported herein was to assess the performance of the freestanding flared single-slope portable concrete barriers according to the safety-performance evaluation guidelines included in the AASHTO MASH, Second Edition (1). The crash tests were performed in accordance with MASH Test Level 3 (TL-3), which requires two crash tests: 1. MASH Test 3-10: An 1100C vehicle weighing 2420 lb, impacting the longitudinal barrier while traveling at 62 mi/h and 25 degrees. 2. MASH Test 3-11: A 2270P vehicle weighing 5000 lb, impacting the longitudinal barrier while traveling at 62 mi/h and 25 degrees. This report provides details on the flared single-slope portable concrete barriers, the crash tests and results, and the performance assessment of the flared single-slope portable concrete barriers for MASH TL-3 longitudinal barrier evaluation criteria. The flared single-slope portable concrete barriers met the performance criteria for MASH TL-3 longitudinal barriers.
