Armorcast Gawk Screen on F-Shape Barrier (deter pedestrians)

Report Number(s): 0-7082

Description: The installation consisted of a 100-ft long section of a cast-in-place F-shape concrete median barrier, with a 79-ft 9-inch section of Armorcast® gawk screen panels mounted on top starting from the upstream end of the F-shape barrier. The F-shape barrier was 32 inches tall, 24 inches wide at its base, and sloped upward on both sides for a final width of 9½ inches at the top of the barrier. The gawk screens were 63 inches long, with a 6-inch overlap, so each individual barrier spanned 57 inches. The screens were 24 inches tall, and had a 6-inch wide 1-inch tall base that sloped up on both sides for a final width of 2 inches at the top of the screen. The screens had two 9 ⁄16-inch wide slots vertically spaced on one end and two 9 ⁄16-inch holes vertically spaced on the opposite end in order to bolt the screens end to end on top of the F-shape barrier. Each screen was fixed to the barrier by being placed over a 26-inch tall post that was anchored to the top of the concrete barrier. The posts were centered on their respective screens, and a hitch pin attached to a chain welded to the inside of the post was inserted into a ¼-inch through hole in order to keep the screens from being easily removed from the posts.
