ASPIRE Burnt River Bridge Replacement

Pdf Summary

The Oregon Department of Transportation (ODOT) successfully constructed the U.S. 30 Burnt River Bridge replacement project using precast, prestressed high-performance concrete (HPC) deck panels composite with precast, prestressed concrete bulb-tee girders and ultra-high-performance concrete (UHPC) connections. The bridge consists of four precast, prestressed concrete bulb-tee girders supporting fifteen precast, prestressed HPC deck panels. The use of precast concrete decks provides increased durability, faster construction, and improved quality. The long-term vision for ODOT includes increased use of precast concrete deck panels in bridge construction. The deck panels were connected using UHPC in panel to girder connections and built-up haunch sections, in order to develop composite action between the deck panels and girders. The UHPC design strength for this project was 14 ksi at 14 days and 17 ksi at 28 days. The haunches were cast using UHPC, with compressible foam backer rod forming the haunch sections. ODOT anticipates that precast concrete deck panels will be more desirable on higher-volume routes where the improved durability will result in significantly lower future maintenance costs. The agency believes that there will be future projects where durability or accelerated bridge construction (ABC) will favor precast concrete deck panels over traditional construction. ODOT sees a future where precast concrete could be the predominant deck type in the state of Oregon.
