NCHRP Report 350 Testing and Evaluation of NETC Bridge Rail Transitions Final rept. (May 2004-Jun 2005)

摘要

The objective of the proposed research study was to qualify transitions to the two bridge rail systems and to a concrete end wall that is used as a component of several bridge rail systems. The NETC New Hampshire transition to the two-bar steel bridge rail successfully contained and redirected the pickup for TL-3 test conditions. All occupant risk values were acceptable. The NETC Massachusetts transition to the concrete end wall successfully contained and redirected both the pickup and the single unit truck for TL-4 test conditions. All occupant risk values were acceptable where applicable. This report presents the details of each installation tested, a description of the testing, and assessment of the tests.
