Title: PROPERTIES OF GUARDRAIL POSTS FOR VARIOUS SOIL TYPES
Accession Number: 00196616
Record Type: Component
Availability: Find a library where document is available Abstract: Pendulum tests on two typical guardrail posts installed in five different soil types are discussed. The purpose of the tests was to determine post property variations as a function of soil conditions. Results of the tests were then used for post input properties in the BARRIER V11 computer program to estimate the ultimate effect of soil conditions on guardrail performance. It is shown that guardrail installations less than the recommended minimum length of 45.7 m (150 ft) can be expected to fail with the more severe impacts when installed in the poorer soils. For vehicle containment and redirection with barrier lengths of 45.7 m or greater, the end posts should be sufficiently anchored to develop the full strength of the post in the lateral direction, as well as the usual longitudinal anchorages. /Author/
