Demonstration of Polyolefin Fiber Reinforced Concrete in a Bridge DeckReplacement

摘要

This report presents the construction and performance evaluation of a full depthbridge deck, and jersey barrier constructed with a new type, non-metallic fiber reinforced concrete (NMFRC). The mixture proportions used, the quality control tests conducted for the evaluation of the fresh and hardened concrete properties, the procedure used for mixing, transporting, placing, consolidating, finishing, tining and curing of the concrete are described. Periodic inspection of the bridge deck and jersey barrier was done and this report includes the results of these inspections. The feasibility of using this NMERC in the construction of highway structures has been established. The new NMFRC with enhanced fatigue, impact resistance, modulus of rupture, ductility and toughness properties is suitable for the construction of a bridge deck and jersey barrier.
