ABSTRACT

Several work-zone traffic control devices have not yet been evaluated to the American Association of State Highway and Transportation Officials’ (AASHTO’s) Manual for Assessing Safety Hardware, Second Edition (MASH 2016) safety performance criteria. In this study, two identical Type III barricades were evaluated in the same crash test, according to MASH 2016, test designation no. 3-72. In test no. WZNP-2, a 5,001-lb (2,268-kg) pickup truck impacted System A, oriented at 90 degrees or perpendicular to the vehicle, at a speed of 64.7 mph (104.2 km/h) and System B, oriented at 0 degrees or head on to the vehicle, at a speed of 62.6 mph (100.8 km/h), respectively. The devices were spaced 60 ft (18.3 m) apart and each device impacted at the quarter-points on the front bumper. Each Type III barricade consisted of three horizontal High Density Polyethylene (HDPE) panels, measuring 96 in. (2,428 mm) in length, with a 48-in. x 30-in. x 0.08-in. (1,219-mm x 762-mm x 2-mm) aluminum sign attached to the top two barricade panels. The barricade panel was targeted to have a cross-sectional dimension of 8 in. (203 mm) x 1 in. (25 mm). During test no. WZNP-2, the 2270P pickup truck readily disengaged both barricades from their support. Both tests successfully met all evaluation criteria in MASH 2016 for test designation no. 3-72.
