Abstract:

The high temperature anti-rutting performance, water stability and low temperature bending property of epoxy asphalt mixture with 0%, 15%, 25%, 40%, and 70% granulated and circular lightweight aggregates by weight are tested, respectively. The dynamic responses under the vehicle load and in the opening process are analyzed to obtain the mechanical responses of pavements by using the finite element method. The complicated structure including a steel deck and a waterproof adhesive layer is made to verify the bond strength of the 2451-type epoxy asphalt binder. Research results show that the epoxy asphalt mixtures with lightweight aggregate replacement percentages from 0% to 70% all satisfy the requirements for steel bridge pavements. The epoxy asphalt mixture with a 70% circular lightweight aggregate replacement percentage is recommended because of its smaller density when compared with other epoxy asphalt mixtures. The shear stress increases with the increase in the opening angle and achieves its maximum at the maximum opening angle of 85°. Test results show that the Tianjin Bascule Bridge can be used for first opening after a 3 d pavement conditioning.
