• Abstract:
  A portable precast concrete, traffic barrier has been designed which utilizes 15 ft (4.6m) barrier segments. The barrier should be much more portable than barriers currently in use in Texas which employ 30ft (9.1 m) segments. Barrier segments are attached with two C5x9 steel splice channels and four 1-1/8 in. (2.86 cm) steel bolts. This joint construction provides significant joint moment capacity without Significantly complicating barrier installation. The barrier was successfully crash tested with a 4500 lb. (2045 kg) vehicle impacting at 25 degrees and 60 mph (96.6 km/h). The test vehicle was smoothly redirected, and vehicle accelerations were within nationally accepted guidelines. No barrier segments were damaged during testing, and only a few splice channels required repair or replacement. Portable barriers currently in use on Texas highways were damaged more severely when tested under identical conditions.
