Abstract:

In order to study the dynamic performance of the thermosetting epoxy asphalt mixture(EAM), an experimental program on the dynamic modulus |E^*| is conducted. First, |E^*| of the EAM under different temperatures and frequencies are tested through the simple performance test(SPT), and the effects of temperatures and frequencies on the dynamic modulus of the EAM are analyzed. Secondly, the static modulus of the EAM and the dynamic modulus of other two ordinary mixtures are tested and compared to |E^*| of the EAM. Finally the dynamic modulus master curve is constructed using the time-temperature superposition principle. The results show that the |E^*| values increase with the increase in the test frequency while on the other hand, the |E^*| values decrease with the increase in the test temperature. It also can be seen from the results that the dynamic modulus corresponding to the actual vehicle mode is significantly greater than the static modulus, and the dynamic modulus of the EAM is greater than that of SBS mixtures and the common hot mixed asphalt(HMA). The study results can provide a theoretical basis for the design and mechanical analysis of the steel deck pavement.
