Title: BRIDGE RAIL TO CONTAIN AND REDIRECT 80,000-LB TANK TRUCKS
Accession Number: 00457488
Record Type: Component
Availability: Find a library where document is available Abstract: A standard Texas Type T5 traffic rail was modified to increase its height and strength to contain and redirect an 80,000-lb (36,297-kg) tank-type tractor-trailer at 50-mph (80.5-km/hr), 15-degree impacts. The height of the concrete parapet was increased to 48 in. (122 cm), 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 and 15-degree 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.
