摘要：

为研究微波加热对沥青老化程度的影响,通过室内模拟对不同加热方式下沥青混合料短期老化过程的模拟和对比分析,揭示微波加热对沥青老化程度的具体影响. 未来研究可进一步探索微波加热条件下沥青老化的机理和影响因素,为沥青路面的养护、维修和回收提供更加精准的技术支持. 分析试验包括常规性能试验、沥青的 4组分分析试验及傅里叶红外光谱(FTIR)试验.

Microwave heating, as a new type of asphalt heating method, can be used to study the specificinfluence of microwave heating on the aging degree of asphalt by simulating and comparing the short⁃termaging process of asphalt mixtures under different heating methods, considering that asphalt hardly absorbsmicrowaves. This reveals the specific influence of microwave heating on the aging degree of asphalt.Future research can further explore the mechanisms and influencing factors of asphalt aging undermicrowave heating conditions, providing more precise technical support for the maintenance, repairing,and recycling of asphalt pavements. The experimental analysis includes conventional performance tests,asphalt four⁃component analysis tests, and Fourier transform infrared spectroscopy (FTIR) tests.
