Construction method for paving expressway with asphalt concrete
The invention discloses a construction method for paving expressway with asphalt concrete. The method comprises steps of material mixing, paving and compacting; wherein the materials are mixed duringmixing, four kinds of asphalt concrete, including a material A, a material B, a material C and a material D, are prepared; the material A comprises asphalt, coarse aggregate, fine aggregate, chinlon 66 and filler I, the material B comprises asphalt, coarse aggregate, fine aggregate, metal fibers and filler I, the material C comprises asphalt, coarse aggregate, fine aggregate, chinlon 66 fibers, metal fibers and filler I, and the material D comprises asphalt, coarse aggregate, fine aggregate, chinlon 66 fibers and filler II; and in the step of paving, the material A, the material B, the material C and the material D are sequentially spread. When the asphalt concrete is prepared, the fibers are added, due to the flexibility of the fibers, the toughness of the asphalt concrete mixed with thefibers is enhanced, and cracks of a pavement are greatly reduced.
本发明公开一种铺设高速公路沥青混凝土的施工方法，包括材料拌和摊铺压实步骤，其中材料拌和时，配制了四种沥青混凝土，包括A料、B料、C料和D料，其中，A料中包括沥青、粗集料、细集料、锦纶66和填料Ⅰ，B料中包括沥青、粗集料、细集料、金属纤维和填料Ⅰ，C料中包括沥青、粗集料、细集料、锦纶66纤维、金属纤维和填料Ⅰ，D料中包括沥青、粗集料、细集料、锦纶66纤维和填料Ⅱ；摊铺是依次摊铺A料、B料、C料和D料。本发明在配制沥青混凝土时，添加了纤维，由于纤维的柔韧性，混有纤维的沥青混凝土韧性增强，大大减少了路面的裂纹。
