Louisiana has approximately 160 movable bridges, mostly in the southern part of the state. The typical deck systems in these movable bridges are steel grids. Records show that steel grids have had maintenance issues. Four alternative high performance concrete (HPC) bridge deck configurations were developed for Louisiana’s movable bridges using four unique concrete mixtures. The development of each concrete mixture is presented. Additionally, each mixture is characterized in terms of its compressive strength, tensile strength, modulus of elasticity, and Poisson’s ratio. Several nonlinear finite element analyses are performed to simulate the behaviour of all four deck configurations from the onset of loading to failure. AASHTO’s ultimate load demand is met regardless of which deck configuration is selected. The panel that features the LHWPC 130 mix exhibited the highest peak load and offers the simplest geometry. |
