2284 Evaluation of Ultra-High Performance Concrete, Fiber Reinforced Self-Consolidating Concrete, and MALP Concrete for Prestressed Girder Repair

The objectives of the proposed research are intended to achieve the goal of using ultra-high performance concrete (UHPC), fiber reinforced self-consolidating concrete (FR-SCC), and MALP concrete to construct durable repairs to continuity joints and end regions of Oklahoma prestressed concrete bridge girder systems. These objectives consist of the following: (1) Identify best practices for mixing and placement of thin encapsulation repairs using UHPC, FR-SCC, and MALP concrete; (2) Evaluate cracking resistance and contribution of thin UHPC, FR-SCC, and MALP concrete repairs to structural strength; (3) Implement UHPC, FR-SCC, and MALP concrete repairs to an in-service bridge and monitor over time; (4) Create specifications for UHPC, FR-SCC, and MALP concrete materials, mixing, placement, and quality control for use in Oklahoma bridge repair. The research will directly result in information and guidance ODOT can use to implement UHPC, FR-SCC, and MALP concrete repairs in the future
