End Treatment for Concrete Barriers Used in Work Zones

An end treatment was developed and crash tested to shield the ends of the concrete safety shape barrier (CSSB) and other narrow rigid objects. It was designed as a temporary treatment for use primarily in construction zones. Steel barrels, some empty and some containing sand ballast, were used in conjunction with collapsing W-beam (guardrail) in the design. Factors considered in its development were cost, portability, ease of installation, and the use of readily available components.
