Reverse twist turned-down terminal for road guardrail systems |
摘要 |
A turned-down terminal for a guardrail system has a drop-down section and a turned-down section formed by twisting the guardrail clockwise to be at an angle causing sufficient force and torque to pull at least a portion of the drop-down section of the guardrail barrier free upon being impacted with a vehicle. Back-up plates are bolted to the posts and to the guardrail.
