MASH Evaluation of F-Shape and Single-Slope Concrete Barriers with Drainage Scuppers
Washington State Department of Transportation (WSDOT) desired to evaluate F-shape and single slope concrete barriers with 6-inch tall drainage scuppers for compliance with American Association of State Highway and Transportation Official’s (AASHTO) Manual for Assessing Safety Hardware (MASH) evaluation criteria. The F-shape was a temporary concrete barrier with pin-and-loop connection. It was evaluated as a free-standing and a pinned-down barrier system on asphalt pavement. The single slope concrete barrier was comprised of 12.5-ft precast barrier segments that were connected using the grouted rebar grid connections. The single slope barrier system was embedded 4 inches in asphalt. The free-standing and pinned F-shape barrier systems were evaluated for MASH Test Level 3 (TL-3) criteria by performing MASH Test 3-11. The single slope barrier was evaluated for MASH Test Level 4 (TL4) criteria by performing MASH Test 4-12. The pinned-down and the free-standing F-shape barriers with drainage scuppers passed the criteria for MASH Test 3-11 for longitudinal barriers. The embedded single-slope barrier with drainage scuppers also performed acceptably for MASH Test 4-12 for longitudinal barriers
