Asphalt concrete pavement construction method
The invention relates to the field of pavement construction, and particularly discloses an asphalt concrete pavement construction method. The method comprises the following steps: 1) heating the asphalt to 95-105 DEG C in a sealed container, exhausing the gas in the sealed container continuously under negative pressure and feeding the gas into cooling water to generate a layered liquid and preheated asphalt after heating the asphalt; 2) controlling the temperature of the layered liquid to be 30-35 DEG C, and filtering the layered liquid to obtain filtrate and filter residues; 3) standing and layering the filtrate, and collecting supernatant; 4) putting the preheated asphalt and the supernatant into a stirring kettle, heating to 190-200 DEG C, and uniformly mixing to obtain pretreated asphalt; 5) adding aggregate and a high-molecular modifier into the pretreated asphalt, heating to 230-240 DEG C, and uniformly mixing to obtain asphalt concrete; 6) paving the asphalt concrete on the pavement base layer, and performing pressing and maintenance to obtain the asphalt concrete pavement. The method has the advantage of widening the application range of the asphalt concrete pavement.
本发明涉及路面施工领域，具体公开了一种沥青混凝土路面施工方法，包括以下步骤：步骤1），将沥青在密封容器中加热至95‑105℃，持续负压抽出密封容器中气体，将抽出的气体通入冷却水中，获得分层液，加热后的沥青为预热沥青；步骤2），控制分层液温度为30‑35℃，过滤分层液获得滤液和滤渣；步骤3），将滤液静置分层，取上层液；步骤4），将预热沥青、上层液投入搅拌釜中，加热至190‑200℃，混合均匀，获得预处理沥青；步骤5），在预处理沥青中投入骨料、高分子改性剂，加热至230‑240℃，混合均匀，获得沥青混凝土；步骤6），在路面基层上铺摊沥青混凝土，压平，养护，制得沥青混凝土路面。本发明具有提高沥青混凝土路面的适用范围的优点。
