The objective of this research was to evaluate the MASH Test Level 3 (TL-3) performance of an F-shape Portable Concrete Barrier (PCB) pinned to concrete. The barrier was installed with a 9-inch offset from the edge of an 8-inch thick unreinforced concrete pavement.
This report provides details of the F-shape PCB pinned to concrete, detailed documentation of the crash test results, and an assessment of the performance of the PCB per MASH Test 3-11 evaluation criteria.
The MASH Test 3-11 was performed with a 2270P test vehicle impacting the barrier at a target impact speed and angle of 62 mi/h and 25°, respectively. The F-shape PCB pinned to the 8-inch thick unreinforced concrete pavement, with a 9-inch offset from the edge of the pavement, performed acceptably for MASH Test 3-11 for longitudinal barriers.
