Crash System Development and Testing of Round Guardrail Posts
Objectives:
*Determine dynamic material properties for two sizes per species of round Southern Pine, ponderosa pine, and Douglas-fir posts.
*Test two embedment depths of round Southern Pine, ponderosa pine, and Douglas-fir posts to allow a recommendation of embedment depth for round posts made from these species.
*Determine possible grading practices for round guardrail posts of Southern Pine, ponderosa pine, and Douglas-fir.
*Use Barrier VII computer simulations to make recommendations for round post guardrail systems for Southern Pine, ponderosa pine, and Douglas-fir.
*Conduct full-scale crash tests at the Midwest Roadside Safety Facility (MRSF) crash test site in Lincoln, Nebraska.
*Produce an installation manual and plans for round post guardrail systems made of Southern Pine, ponderosa pine, and Douglas-fir.
