Transitions from guardrail to bridge rail that meet safety performance requirements Buth, C Eugene et al
Utgivningsinformation: Transportation Research Record, 2000Beskrivning: nr 1720, s. 30-43Ämnen: Bibl.nr: VTI P8167:1720Location: Abstrakt: Three guardrail-to-bridge rail transitions were developed and subjected to full-scale crash tests. The transitions were (a) a nested W-beam with W-beam rub rail that transitioned from a W-beam guardrail to a vertical concrete parapet bridge rail, (b) a nested thrie-beam that transitioned from a W-beam guardrail to a tubular steel bridge rail, and (c) a tubular steel transition that transitioned from a weak-post box-beam guardrail to a tubular steel bridge rail. The nested W-beam and the tubular steel transitions were tested and met NCHRP Report 350 Test Level (TL)-3 requirements. The nested thrie-beam transition was tested and met TL-4 requirements.| Aktuellt bibliotek | Hyllsignatur | Status | Förfallodatum | Streckkod | |
