PennDOT 50-inch Tall Precast F-shape Concrete Barrier Keyed in 4- inches of Asphalt

Report Number(s): TTI 611851, 1-4

Description: The test installation was comprised of 8 precast, steel reinforced concrete barrier segments keyed in 4-inches of asphalt. Each barrier segment was 12 ft long, and adjacent barrier segments were connected to each other with drop-in pins through loops that were cast into the barriers. There was an approximately 2 inch space between the barriers, for a total length of approximately 97 ft-2 inches. Each barrier was 54 inches tall, 5 inches wide at top, and 24 inches wide at bottom. A 4-inch thick layer of asphalt, 9 ft wide, was placed on the traffic and field sides of the barriers, resulting in a 50-inch height from grade to the top of the barriers.
