Free Standing Temporary Concrete Barrier

Report Number(s): 690900-WSP-1&2A

Description: The installation consisted of 16 reinforced concrete barriers, each 12.5 ft long, for a total installation length of approximately 200 ft. Two ⅞-inch diameter B7 threaded rods, with a plate washer, hardened washer, and heavy hex nut on each end, connected adjoining barriers to each other in an “X-pattern” with recesses cast into each end of each barrier. The barriers were 9½ inches wide at top, 24 inches wide at bottom, and 32 inches tall. Each barrier had two 3-inch tall × 22-inch long scuppers at bottom, and three slotted holes on each side to receive anchor pins. However, anchor pins were not used for this test installation, as all barriers were unrestrained to the road surface.
