| 摘要： | The purpose of this study is to crash test and evaluate new or modified roadside safety hardware and, where necessary, redesign the devices to improve their impact performance. The three major areas addressed in this study are the impact performance of bridge railings, transitions from guardrails to bridge railings, and end treatments for guardrails and median barriers. This crash tests conducted under this study. A total of 36 full-scale crash tests were conducted, covering 12 different types of roadside safety appurtenances. The crash tests were conducted in accordance with guidelines set forth in National Cooperative Highway Research Program (NCHRP) Report 230, NCHRP Report 350, and/or the 1989 American Association of State Highway Transportation Officials (AASHTO) Guide Specifications for Bridge Railings, depending on the specific appurtenance being tested. In addition, laboratory and pendulum tests were conducted on a modified breakaway modified eccentric loader terminal (MELT) post design. |
