Development of standards for placement of steel guardrail posts in rock

Development of standards for placement of steel guardrail posts in rock /

A steel post W-beam guardrail system was developed for installation in rock-soil foundations. The guardrail system was constructed with a 2.66-mm (12-gauge) thick W-beam rail, 53.34 m in length. The W-beam guardrail was supported by 27 W152x13.4 by 1,346-mm long steel posts, spaced at 1,905 mm on ce...
