摘要
微波加热和红外加热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加热和红外加热下的各项性能,通过试验研究,系统分析了微波加热沥青混合料和红外加热沥青混合料的路用性能,包括高温变形特性、低温抗裂性、水稳性和抗疲劳特性试验。结果表明:微波加热沥青混合料具有较红外加热和普通密级配沥青混凝土更好的路用性能,可以改善沥青混凝土路面使用品质,具有较好的经济和社会效益,在沥青混凝土路面维修中的应用前景十分看好。
Microwave heating and infrared ray heating are used in maintenance of asphalt concrete pavement of high grade expressways. In order to evaluate the performance of asphalt concrete pavement in the microwave heating and infrared ray heating, a series of tests are carried out to analyze the characteristics of high temperature rutting, low temperature crack resistance, water stability, fatigue resistance. Finally the results show that the microwave heating asphalt mixtures have better road performance than others, and have better social and economic value. Its application has a good prospect for maintenance of asphalt concrete pavement.
