ABSTRACT

Two bridge railing and approach guardrail transition systems for use on bridges with transverse glue-laminated timber decks were developed and crash tested for use on medium-service-level roadways. The bridge railing and transition systems were subjected to full-scale crash tests in accordance with the Test Level 2 (TL-2) safety performance criteria presented in NCHRP Report No. 350, Recommended Procedures for the Safety Performance Evaluation of Highway Features. The first railing system was constructed with steel hardware, whereas the second railing system was configured with glulam timber components. Four full-scale crash tests were performed, and the bridge railing and transition systems were acceptable according to current safety standards.
