Development and Test of an Optimized MASH TL-4 Concrete Bridge Rail
Report Number(s): TRP-03-415-21
Description: The bridge rail was designed with a 39-in. installation height so that it would remain crashworthy after future roadway overlays up to 3 in. thick. The barrier had a front face with a 3-degree slope (i.e., batter) away from vertical to promote vehicle stability during impacts while also providing some slope to allow for slipforming real-world installations.
