Asphalt concrete preparation process
The invention relates to the technical field of asphalt concrete, in particular to an asphalt concrete preparation process. The preparation method comprises the following steps: a material treatment process: aggregate collection, material frying and vibratory screening to obtain screened aggregate for later use; heating and melting the asphalt material to obtain a molten modified asphalt material for later use; in the mixing treatment process, the screened aggregate and the molten asphalt material are mixed, and asphalt concrete is obtained; the aggregate is prepared from broken stone, stone chips and mineral powder, and the asphalt-aggregate ratio is 3.8-6.0%. Through stir-frying, the temperature of the screened aggregate is increased; according to the present invention, the asphalt material has good dispersibility, such that the asphalt material can be well fused with the screened aggregate after the asphalt material is fused so as to obtain the uniformly-mixed asphalt concrete, and after the asphalt concrete is solidified, the modified asphalt material and the screened aggregate are tightly bonded so as to provide the good stability and the good strength after the asphalt concrete forms the pavement.
本申请涉及沥青混凝土的技术领域，更具体地说，它涉及一种沥青混凝土制备工艺。用以下方法得到，物料处理过程：收集骨料，炒料，振动筛分，得到筛分的骨料，备用；沥青物料进行加热熔融，得到熔融的改性沥青物料，备用；混料处理过程：将筛分的骨料和熔融的沥青物料进行混合，得到沥青混凝土；骨料由碎石、石屑以及矿粉，油石比为3.8‑6.0%。通过炒料，使筛分的骨料的温度升高；沥青物料具有较好的分散性，使沥青物料熔融后能够与筛分的骨料很好地融合，进而得到混合均匀的沥青混凝土，当该沥青混凝土凝固后，改性沥青物料与筛分的骨料紧密粘结，使得沥青混凝土形成路面后具有较好的稳定性和强度。
