• Abstract:
  A standard Texas type T5 traffic rail was modified to increase its height and strength to contain and redirect an 80,000 1 b (36,300 kg) tank-type tractor trailer at 50 mph (80.5 km/h), 150 impacts. The concrete parapet was increased to 48 in. (122 cm) high, and a concrete beam was mounted on concrete posts on top of the parapet to achieve a total rail height of 90 in. (229 cm). One crash test was conducted on the bridge rail. The truck was contained and smoothly redirected. This test has shown that a bridge rail can redirect heavy tank-type trucks at speeds up to 50 mph (80.5 km/h) and 150 impacts. The cost of this rail is estimated at about $125 per foot. Typical passenger car bridge rails in Texas now cost about $35 per foot.
