Guardrail connection for low-fill culverts
KA Polivka, RK Faller… - Transportation research …, 2003 - journals.sagepub.com
A W-beam guardrail system was developed for attachment to the top slab of a low-fill
concrete culvert. The guardrail design was constructed with a single, 2.66-mm-thick W-beam
rail totaling 53.34 m in length. Over the culvert, W150× 13.5 steel posts 946 mm long spaced
952.5 mm on center supported the W-beam rail. The research study included dynamic
testing with a bogie vehicle and steel posts attached to a rigid foundation, computer
simulation modeling with BARRIER VII, and two full-scale vehicle crash tests. The crash …

In this research, a W-beam guardrail system was developed for installation with the steel
post attached to the top of a low-fill concrete culvert. The guardrail system was constructed
with a 2.66-mm (12-gauge) thick W-beam rail totaling 53.34 m in length. The post spacing
was 1,905-mm on center for post numbers 1-9 and 33-41, while the post spacing for post
numbers 9-33 was 952.5-mm on center. Two full-scale vehicle crash tests, using 3/4 ton
pickup trucks, were performed on the W-beam guardrail system. One test was successfully …
