REPAIR AND MAINTENANCE MANUAL FOR THE NARROW CONNECTICUT IMPACT-ATTENUATION SYSTEM (NCIAS)

In a continuing effort to develop improved vehicular impact-attenuation devices, the Connecticut Department of Transportation has introduced its third cylindrical steel highway crash cushion, known as the Narrow Connecticut Impact-Attenuation System (NCIAS). Differing from the first (truck-mounted systm) and the second (wide stationary system), the NCIAS is a stationary system designed to protect motorists from impacting narrow, rigid roadside features such as bridge piers and blunt ends of concrete longitudinal barriers. This manual describes the materials and procedures required to properly repair and maintain the NCIAS. This information is presented under the following headings: Introduction; Importance of Proper Maintenance; Description of the NCIAS; Damage Assessment and Replacement Parts; Tools and Equipment Required for Repair; Disassembly; Reassembly; Cover Attachment; Long-Term Maintenance; and Parts List.
