Samenvatting
Development of the guardrail extruder terminal (get), a low-costend treatment for w-beam guardrails, is presented in this paper. When impacted, this end treatment causes the w-beam to be flattened and deformed in a controlled manner ahead of the impacting vehicle. The flattening process dissipates energy, and impacting vehicles are decelerated to a controlled stop. The paper discusses static and dynamic laboratory testing of extruder components as well as full-scale crash tests of the get. The get is shown to be in compliance with nationally recognised impact performance standards.
