Abstract:The objective of this study was to crash test and evaluate these transitions according to requirements of NCHRP Report 350. The scope of this study is as follows:“This study will crash test a series of thrie beam transitions from guardrails to bridge rails in accordance with the appropriate test levels of National Cooperative Highway Research Program (NCHRP) Report 350. These transition designs were selected by the State representatives for State Planning and Research (SP&R) Pooled Fund Study No. 2-134, “Testing New Bridge Rail and Transition Designs.” The following transitions were tested under this project: • Ohio Nonsymmetrical Type 2 W-beam to Thrie Beam Transition. < With 12-gauge nonsymmetrical transition section. < With 10-gauge nonsymmetrical transition section. • Ohio Type 1 Thrie Beam Transition to Concrete Parapet. < Type 1 without curb. < Type 1 with asphalt curb. • Thrie Beam Transition to Wisconsin Type “M” Tubular Steel Bridge Rail. • New York State Department of Transportation (DOT) Modified Box Beam Transition to Four-Rail Steel Bridge Rail. All designs were tested to NCHRP Report 350 Test Level 3, except the Ohio Type 1 Thrie Beam Transition to Concrete Parapet with Asphalt Curb, which was tested to Test Level 4.
