Abstract

As one of the major diseases of asphalt pavement, rutting has become an important research topic. The current treatment method of rutting generally requires the milling of asphalt layers and construction of a new overlay, which is time-consuming and costly. Microwave heating is a promising technology for asphalt pavement maintenance. This research aimed to introduce microwave heating into the in situ rutting rehabilitation. The effects of microwaves on the aging of asphalt and mechanical properties of asphalt mixtures were discussed. The mechanism and effects of microwave maintenance were explored at the macroscopic and microscopic scale with the British Pendulum Test, X-ray Computed Tomography, Asphalt Extraction Test, and Discrete Element Method. The experiments showed that the microwaves have little negative effect on the performance of asphalt and asphalt mixtures. The analysis of the formation process of rutting showed that asphalt or asphalt cement shows bottom-up migration while the coarse aggregates move down. Overall, the research indicates that the general effect of microwave maintenance is an improvement in the rutting resistance of asphalt pavement, suggesting that rutting maintenance using microwave heating is feasible in practice.
