Crash Cushions (Road Safety)

Safety Guard(Crash Cushions)

Introduction

Crash cushions are devices designed to reduce the severity of an impact by preventing the errant vehicle from roadway from crashing with fixed structures and dangerous articles.

These devices are distinguished from ozone-resistance, heat-resistance and cold-resistance. Also it is more inexpensive for repairing devices than other structures as using butyl-rubber and being able to recycle it after crashing.
The structures are not only transformed backward by supporting those structures with Rail and Plate ,but also able to relocate it on side-crashing accident.
Also, Safety Guard prevents second-accidents by using the materials leaving no remains when crashing.
It is efficient for checking the structures by inspecting external appearance on driving.

Safety Guard is certified by Korea Expressway Corporation through developing with Highway and Transportation Technology Institute. It was performed by thousands of rubber mixings , crashing experiments with a model and computer analysis. As well as, the stability of structures and the absorbing capability of impact energy were confirmed through thousands of crashing tests. Safety Guard is a structure based on thousands of crashing analysis and experiment data.

Crash cushions are used to reduce the severity of an impact when crashing with fixed structures and dangerous articles.
