Construction method of expressway asphalt concrete
The invention discloses an expressway asphalt concrete construction method and relates to the technical field of expressway construction. The expressway asphalt concrete construction method comprises the following steps of preparing an asphalt concrete raw material and an asphalt concrete base layer in advance, keeping the temperature at 140-160 DEG C during construction, continuously paving and constructing by a paver at a constant speed of 2-4 m/min, paving the asphalt concrete base layer in advance, the laying thickness being 10 cm, initial pressing being carried out to ensure that the internal temperature of the asphalt concrete is 140-160 DEG C, and re-pressing being carried out to ensure that the internal temperature of the asphalt concrete is 160-180 DEG C. The method is advantaged in that high and low temperature, water stability and working performance of the asphalt concrete are improved, the proportion of the asphalt concrete is increased, rutting resistance is improved, in addition, toughness of the asphalt concrete mixed with the polyamide fibers and the metal fibers is enhanced, cracks of a pavement are reduced, the heat conduction component and the EVA hot melt adhesive can avoid excessive softening of pavement asphalt caused by overhigh pavement temperature of the expressway, and in addition, the silicon rubber waterproof agent coating can prolong the service life of the pavement.
本发明公开了一种高速公路沥青混凝土的施工方法，涉及高速公路施工技术领域，包括以下步骤：预先制备沥青混凝土原料和沥青混凝土基层，在施工中的温度保持140‑160℃，且摊铺机匀速连续摊铺施工，速度为2‑4m/mi n，预先铺设沥青混凝土基层，铺设的厚度为10cm，进行初压保证沥青混凝土内部温度为140‑160℃，再进行复压保证沥青混凝土内部温度为160‑180℃。本发明改善沥青混凝土的高低温、水稳和工作性能，而且提高沥青混凝土的比例，使得抗车辙性能得到提升，另外通过混有锦纶纤维和金属纤维的沥青混凝土韧性增强，减少了路面的裂纹，而导热成分和EVA热熔胶可避免高速公路的路面温度过高而造成路面沥青过度软化，另外硅橡胶防水剂涂层可提高其使用寿命。
