Crash Testing and Evaluation of the HDOT 42-In. Tall, Solid Concrete Bridge Rail with Aesthetic Recessed Rounded Panels and 6-in. Tall Sidewalk: MASH Test Designation Nos. 3-10 and 3-11

Report Number(s): TRP-03-455-22

Description: The test installation consisted of a reinforced concrete bridge rail and sidewalk anchored to the existing concrete tarmac at MwRSF’s Outdoor Test Site, rather than a simulated bridge deck and overhang. Previous testing of a MASH 2016 TL-4 bridge rail on a similar 8-in. thick concrete bridge deck displayed no deck damage, indicating the potential for deck damage or deflection that would affect the outcome of the full-scale crash test was minimal under MASH 2016 TL-3 impact conditions. HDOT’s 42-in. Tall, Aesthetic Concrete Bridge Rail with 6-ft Sidewalk was constructed to an effective rail height of 42 in. relative to the 6-in. tall sidewalk. The reinforced concrete bridge rail had a total length of 88 ft and measured 42 in. tall and 10 in. wide. The barrier had a vertical front face with aesthetic recessed panels spaced 12 in. apart, measuring 6 in. wide and 14 in. tall with a 3-in. top-edge radius. Three ½-in. tall x ½-in. deep V-shaped horizontal bevel cuts were etched into each face located 8, 15, and 35 in. above the sidewalk. The top edge of the barrier on each side was chamfered at a 45-degree angle, measuring ¾ in. wide. The reinforced concrete sidewalk had a width of 6 ft and measured 6 in. tall with a 1½-in. finish.
