ABSTRACT
Based on the proposed changes to the National Cooperative Highway Research Program (NCHRP) Report No. 350 guidelines, NCHRP Project 22-14(2) researchers deemed it appropriate to evaluate an end terminal for a strong-post, W-beam guardrail systems prior to finalizing the new crash testing procedures and guidelines. For this effort, the SKT-MGS Tangent End Terminal was selected for evaluation. One full-scale vehicle crash test was performed on the longitudinal barrier system in accordance with the Test Level 3 (TL-3) requirements presented in the Update to NCHRP Report No. 350. For the terminal testing program, an 1100C small car vehicle was used.
The end terminal system, mounted at the metric top rail height of 813 mm (32 in.), provided an
acceptable safety performance when impacted by the small car, thus meeting the proposed TL-3 requirements presented in the Update to NCHRP Report No. 350.
