MASH Test 3-11 On F-Shape Portable Concrete Barrier with X-Bolt Connection

Report Number(s): 0-7086-R1

Description: The test installation consisted of seven 30-ft-long precast steel reinforced portable concrete barrier (PCB) segments placed end to end, for a total length of 210 ft. The barriers were connected to each other using two 29-inch-long sections of a ⅞-inch-diameter B7 threaded rod and associated hardware at each joint. The threaded rod passes through PVC pipe cast into the ends of the barrier segments at two different elevations that form an “X” in plan view. Recesses were cast in the exterior faces of the barriers so that the ends of the threaded rod and associated hardware did not protrude past the exterior faces. All barriers were freestanding (not secured to the concrete apron). The barrier segments measured 24 inches wide at bottom, 9½ inches wide at top, and 32 inches tall. The traffic and field side faces were symmetric, with an F-shape profile.
