我国公路,尤其是高速公路近十年来发展很快,高速公路总里程已位居世界第二,并以惊人的速度发展,其中90%以上为黑色路面。长期以来,沥青路面的大面积维修一般采用开挖重铺的办法,高速公路的大面积维修基本上也采用了这种传统的开挖重铺法,只是开挖方式由大型铣刨机代替了人工开挖,将大量的废料作为垃圾处理,同时用相应的混合料去修复,造成大量的浪费。如果按照沥青路面的设计寿命(15～20年)我国90年代以后陆续建成的高速公路已经进入大、中修期,每年有12%的沥青路面需要翻新,旧沥青路面的废弃量已经达到200万吨以上,1989年-2002年我 China’s roads, especially the expressways, have developed rapidly in the past decade. The total mileage of highways has ranked second in the world and has been developing at an alarming rate, of which over 90% are black roads. For a long time, large areas of asphalt pavement maintenance and repair methods generally used excavation, large-scale maintenance of the highway is basically also used this traditional method of excavation and rebuild, but by way of large milling machine instead of digging Artificial excavation, a large amount of waste as garbage disposal, while using the appropriate mixture to repair, resulting in a lot of waste. According to the design life of asphalt pavement (15 ~ 20 years), the expressways built one after another in our country after 1990s have entered the period of large and medium repairs, and 12% of the asphalt pavement needs to be renovated every year, and the waste of the old asphalt pavement has reached 2 million Ton, more than 1989-2002 me
