[BUCH][B] Full-Scale Vehicle Crash Tests on Guardrail-Bridgerail Transition Designs with Special Post Spacing
ER Post, RJ Ruby, DF Ronnau, MD Cress - 1988 - trid.trb.org
Full-scale 4,500-pound vehicle impact tests at 60 mph and 25 degrees were conducted on
four new guardrail-bridgerail" transition" designs for use in Nebraska in which the first wood
post from the bridge end was left out. The post was left out to represent a common field
problem in which a concrete footing prevents installing the post. To compensate for the
missing post, a stronger beam member and heavier wood posts were used in addition to a 4:
1 tapered end on the concrete bridgerail. The tapered end was used to (1) reduce the …
