Preparation process of asphalt concrete
The invention relates to a preparation process of asphalt concrete, which comprises the following steps: S1, proportioning coarse aggregate, fine aggregate, mineral powder, limestone powder, cement and pulverized coal in proportion through an aggregate mechanism, and stirring and mixing the coarse aggregate, the fine aggregate, the mineral powder, the limestone powder, the cement and the pulverized coal through a first stirrer to obtain a mixture; s2, drying the mixture through a drying roller at 170-180 DEG C to obtain a dry material; s3, the asphalt is heated to 140 DEG C to 160 DEG C; and S4, adding the heated asphalt into the dry material, and stirring and mixing through a second stirrer to obtain the asphalt concrete. Through the arrangement of the material collecting mechanism, the problem that when a plurality of switch valves of an existing material collecting mechanism need to be opened at the same time to achieve specific burdening, complete synchronous opening is difficult to achieve due to small difference in operation is solved.
本发明涉及一种沥青混凝土的制备工艺，包括以下步骤：S1、将粗骨料、细骨料、矿粉、石灰岩粉、水泥和粉煤通过集料机构进行按比例配料，粗骨料、细骨料、矿粉、石灰岩粉、水泥和粉煤通过第一搅拌机进行搅拌混合，得到混合料；S2、混合料通过烘干滚筒在170‑180℃下烘干，得到干料；S3、将沥青加热至140‑160℃；S4、加热后的沥青加入干料通过第二搅拌机进行搅拌混合，得到沥青混凝土。通过集料机构设置避免了现有集料机构存在的需要同时开启多个开关阀以达到特定配料时，由于操作上的微小差异，很难实现完全同步开启的问题。
