对于沥青类道路的维修,日本多采用切削混合铺装法和铺层覆盖法,前者须对旧路面进行加热方能切削和搅拌,而补充加入的新沥青混合物也需是热的,否则新、旧材料就不能很好的混合.后者虽可不必对旧路面加热,但加铺的敷层所用的沥青混合物也必须是热的,否则就无法摊铺.沥青路和水泥路相比,铺筑后能在较短的时间内开放交通,这一点对道路尽快投入运营是十分重要的.但不管是新筑的沥青路还是维修再生的沥青路,虽可比水泥路能较早的投入使用,可铺筑后仍需有
For the maintenance of asphalt roads, Japan uses cutting hybrid paving and overlay method, the former heating the old pavement to be cutting and stirring, and added to join the new asphalt mixture also need to be hot, or new, The old material can not be well mixed.The latter may not have to heat the old pavement, but the asphalt mixture used in the overlay must also be hot, otherwise it can not be paved.Asphalt road and cement road compared to shop It is very important for the roads to be put into operation as soon as possible after the construction of the post-construction and opening up of traffic in a relatively short period of time. However, whether the newly built asphalt road or the asphalt road for maintenance and regeneration can be put into operation earlier than the cement road, Can be paved still need to have
