微波加热是一种全新的热能技术,现已逐渐应用到高等级公路沥青混凝土路面养护和维修中。为了评价沥青混凝土路面在微波辐射加热下的各项性能,利用微波加热设备,研究了微波加热沥青混凝土路面的均匀性和微波加热沥青混凝土路面的最佳厚度。试验结果表明,微波加热有着快速、穿透深度大以及受热均匀一致等优点,在沥青混凝土路面维修中的应用前景十分看好。 Microwave heating is a new thermal technology, has been gradually applied to high-grade highway asphalt concrete pavement maintenance and repair. In order to evaluate the performance of asphalt concrete pavement under microwave irradiation, the uniformity of microwave heating asphalt pavement and the optimum thickness of microwave heating asphalt pavement were studied by using microwave heating equipment. The test results show that the microwave heating has the advantages of fast, large penetration depth and uniform heating, so the application prospects in asphalt pavement maintenance are very promising.
