Drainage and noise reduction type asphalt pavement and construction method thereof
The invention relates to the field of asphalt pavement construction, and particularly discloses a drainage and noise reduction type asphalt pavement and a construction method thereof. The raw materials of the asphalt pavement comprise matrix asphalt, aggregate, fine aggregate, mineral powder, a reinforcing agent, a pore-forming auxiliary agent and water, wherein the pore-forming auxiliary agent is prepared from limestone, polyacrylamide and dipropionic acid; the construction method of the asphalt pavement comprises the following steps: S1, preparing the drainage and noise reduction type asphalt mixture; s2, a construction pavement is cleaned up, and then emulsified asphalt layer sealing is conducted; s3, heating the drainage and noise reduction type asphalt to 130-150 DEG C by adopting an asphalt paver, wherein the paving speed is controlled to be 3-5 meters per minute; and S4, a road roller is used for rolling compaction, and the rolling compaction is mainly divided into three stages including initial rolling, re-rolling and final rolling till separated joints are removed. According to the asphalt pavement, the porosity of the asphalt mixture can be fully improved, so that rainwater can be quickly discharged out of the pavement, and the noise during driving can be reduced.
本申请涉及沥青路面施工的领域，具体公开了一种排水降噪型沥青路面及其施工方法。沥青路面原料包括基质沥青、骨料、细集料、矿粉、增强剂、造孔助剂和水，所述造孔助剂由石灰石、聚丙烯酰胺和联二丙酸制备得到；所述沥青路面的施工方法为：S1、制备排水降噪型沥青混合料；S2、将施工路面清扫干净，然后进行乳化沥青封层；S3、采用沥青摊铺机将排水降噪型沥青加热升温至130‑150℃，摊铺速度控制在每分钟3‑5米；S4、使用压路机进行碾压，主要分为三个阶段：初压、复压和终压，直到去除分离的接缝即可。本申请的沥青路面能够充分提高沥青混合料的孔隙率，从而有利于雨水快速排出路面，并且有利于降低行车时的噪音。
