众所周知,沥青混凝土路面在使用一个时期后,路面会逐渐发生拥包,坑槽、龟裂等病害。在处理这类病害路面时,往往把旧路面上的沥青混凝土除去,然后重新铺筑新路面,在这一过程中,有大量的沥青混凝土旧料需要处理。另外,在城市一些埋设地下管道的工程中,也往往产生大量的沥青混凝土旧料。如何科学地处理这些沥青混凝土旧料是土建工程中一个值得研究的问题。
As we all know, asphalt pavement in the use of a period of time, the road will gradually happen to package, pit, crack and other diseases. In dealing with such disease pavement, it is often removed from asphalt concrete on the old pavement and then paved with new pavement. In this process, a large amount of asphalt concrete raw material needs to be disposed of. In addition, some buried underground pipe projects in the city often also produce a large amount of asphalt concrete raw materials. How to scientifically deal with these asphalt concrete raw materials is a problem worth studying in civil engineering.
