DEVELOPMENT OF GUARDRAIL EXTRUDER TERMINAL

Development of the Guardrail Extruder Terminal (GET), a low-cost end 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 recognized impact performance standards.
