American Association of State Highway and Transportation Officials (AASHTO) Manual for Assessing Safety Hardware (MASH) Test 3-10 was preformed on the Tubular Barrier Gap Rail as reported herein. (1). The test was not successful with respect to the MASH Test 3-10 criteria. Therefore, the design is not acceptable with respect to MASH specifications. These details are reported in the failed system report listed above.

A subsequent redesign effort resulted in a successful design that passed MASH Test 3-10 and 3-11. Details of this redesign is reported in the Redesign Final Report Link.
