Structure Mechanical Study on Overlay of the Tied Arch Concrete Bridge Deck

The structural behavior of the double-layered asphalt concrete Huanghe bridge was analyzed by the FEM (Finite Element Method). The most critical loading location for the bridge pavement was determined, and the control indexes for the asphalt pavement established. For the most adverse loading cases, the variations of asphalt overlays around wheel paths were analyzed and the corresponding three-dimensional graphs presented. To determine the influences of horizontal cyclic loads on the control index, different asphalt overlays under various horizontal cyclic loads were analyzed. To simulate the boundary conditions, the bridge, including beams, arch ribs, suspenders, and pavement were analyzed. Experiments were conducted in coordination with the finite element analysis. A relationship between shearing and bonding strength under varying temperatures was established, also, the interlayer stable control index, and bonding strength under 15°C, were determined. An in-situ pullout test was performed using the pullout apparatus designed by the research team to verify the stability of inter-layers.
