Abstract
An end treatment for a guardrail safety system includes a terminal portion of a guardrail beam comprising a downstream end and upstream end, a first tension cable coupled to an upstream end of the terminal portion. An extruder configured to receive at least a portion of the guardrail beam and at least a portion of the first tension cable, and a terminal support post installed adjacent the roadway at an upstream end of the terminal portion of the guardrail beam. The extruder includes a narrowing throat providing a channel in which at least a portion of the guardrail beam is disposed. The narrowing throat is configured to flatten the guardrail beam in response to a collision with a vehicle moving the extruder in a downstream direction along the guardrail beam. The terminal support post coupled to an upstream end of the first tension cable.
