CONNECTICUT NARROW HAZARD CRASH CUSHION

This paper describes analytical and experimental work that resulted in the development of a nonproprietary crash cushion to be used at narrow hazard sites. Examples of such locations include the ends of edge-of-road and median barriers, bridge pillars, and center piers. The first phase of the experimental program involved a series of scale-model impact tests to verify the energy dissipation predictions of the analytical model and to investigate the lateral stability characteristics of the crash cushion model. In the second phase of the experimental program, full-scale crash tests were conducted in accordance with the requirements of NCHRP Report 230. This new narrow hazard crash cushion satisfies the requirements of that document and is inexpensive to fabricate and repair. In addition, the system possesses a unique, self-contained backup structure, which permits its use as an end treatment for a wide variety of narrow hazards, including concrete barriers and all guardrail systems.
