Book Description
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.
