TxDOT 42-inch Single Slope Concrete Median Barrier with Light Pole

Report Number(s): 0-6946-R2

Description: The test installation was 120 ft long and consisted of a 42-inch-tall reinforced single slope concrete barrier (SSCB) with a light pole mounted approximately 40 ft from one end. The parapet was 9¼ inches wide at the top for a distance of 24 inches centered at the light pole, tapering to 8 inches wide over 48 inches of length each direction. The SSCB was 24 inches wide at bottom for its full length. The 10-ft tapered section to which the light pole was mounted was secured to an 8-inch thick × 24-inch wide reinforced slab. A 1-inch thick × 9 ft wide layer of asphalt was placed on both sides of the installation to provide lateral support for the SSCB. Thus, the height of the barrier above the asphalt overlay was 41 inches. The light pole was mounted to the top of the SSCB following details and specifications of standard sheet RIP(2)-11. The light pole was supplied and installed by a subcontractor under supervision of TTI Proving Ground. The light pole was secured to the top of the barrier using the appropriate concrete barrier anchor bolt assembly detail. The 43-ft tall pole was configured with double mast arms that had a nominal length of 12 ft. The effective mounting height of the luminaires was 48 ft above the top of the barrier.
