Asphalt pavement construction method
The invention relates to an asphalt pavement construction method, and belongs to the technical field of road construction. The method comprises the steps of 1, conducting preparation before construction, specifically, removing soil and sundries on an original pavement and repairing pot holes and pits; 2, preparing and planning toxic gas absorption; 4, conducting slurry seal construction, specifically, using modified emulsified asphalt prepared on site, mixing 2%-3% of ordinary Portland cement with the strength of 42.5 grade, then paving the mixture on a construction pavement, and turning on ahigh-pressure suction fan in advance before paving; 5, conducting prime coat oil and tack coat oil construction, specifically, spraying prime coat oil on the pavement base layer, and spraying tack coat oil between asphalt concrete layers; and 6, conducting construction of an asphalt concrete lower surface layer and an asphalt concrete upper surface layer, specifically, after the spraying of primecoat oil passes inspection and acceptance, mixing an asphalt mixture on site, and immediately paving after the mixing is completed. The construction method has the advantage of reducing toxic gas inhaled by constructors in the construction process of the asphalt pavement.
本发明涉及一种沥青路面施工方法，属于道路施工的技术领域，包括以下步骤：步骤一：施工前准备：清除原始路面上的泥土、杂物以及修补坑槽凹陷；步骤二：毒气吸收准备及规划；步骤四：稀浆封层施工：使用在现场制备的改性乳化沥青，掺2%～3%的强度为42.5级的普通硅酸盐水泥然后摊铺在施工路面上，摊铺之前提前打开高压吸风机；步骤五：透层油及粘层油施工：在路面基层上洒布透层油，在沥青砼层间洒布粘层油；步骤六：沥青混凝土下面层及上面层施工：透层油洒布经过验收合格后，对沥青混合料在现场进行拌合，拌合完成后立即进行摊铺，本发明具有在沥青路面施工的过程中减少施工人员吸入的有毒气体的优点。
