TxDOT C402 Bridge Rail

Report Number(s): 0-6949-R2

Description: The C402 test installation consisted of a 153-ft long reinforced concrete cantilevered deck and parapet with integral steel posts and rails secured to the top of the parapet. The post spacing was 10 ft. The height from the road surface to the top of the parapet was 24 inches, and the overall height to the top of the steel rail was 42 inches. There were three 2-inch wide joints formed in the concrete parapet corresponding with the selected critical impact points. One joint was in the parapet only for geometric evaluation of the passenger car during Test 4-10 (the 1100C test location). The other two joints extended through both the parapet and deck to provide evaluation of both rail geometry and structural adequacy during Tests 4-11 and 4-12. The test installation also incorporated 2-inch wide joints in both the elliptical steel traffic rail and pedestrian pipe rail near the concrete joints based on TxDOT standards. Steel sleeves were inserted into the steel rail members to provide structural continuity across the joints.
