Compression-resistant asphalt pavement mixture and preparation method thereof, and pavement construction method
The invention relates to the field of asphalt preparation, and particularly discloses a compression-resistant asphalt pavement mixture and a preparation method thereof, and a pavement construction method. The asphalt pavement mixture comprises petroleum asphalt, aggregate, a filler, polypropylene fiber, terpene-phenolic resin and inorganic salt. The preparation method comprises the following steps: preheating the terpene-phenolic resin, respectively adding the polypropylene fiber and the inorganic salt into the terpene-phenolic resin, and conducting stirring to obtain a first mixture; mixing the aggregate and the filler, preheating a formed mixture, and adding the preheated mixture into the first mixture to obtain a second mixture; and finally, adding the preheated petroleum asphalt into the second mixture to obtain the asphalt mixture. The pavement construction method comprises the following steps: firstly cleaning a base pavement, then paving and spreading a first layer of asphalt, then paving and spreading a second layer of asphalt, and finally, performing water spraying maintenance on a compacted asphalt pavement. The compression-resistant asphalt pavement mixture has the effect of enhancing the anti-cracking performance of the pavement made of the asphalt mixture.
本申请涉及沥青制备的领域，具体公开了一种抗压沥青路面混合料及其制备方法和路面的施工方法。沥青路面混合料包括石油沥青、集料、填料、聚丙烯纤维、萜烯酚树脂、无机盐；其制备方法为：将萜烯酚树脂预热，分别将聚丙烯纤维与无机盐加入萜烯酚树脂中并搅拌得到第一混合物，然后将集料和填料混合后预热再加入至第一混合物内，得到第二混合物，最后将预热后的石油沥青，加入到第二混合物内得到沥青混合料；路面的施工方法为：首先清扫基层路面，然后摊铺第一层沥青并碾压，接着摊铺第二层沥青并碾压，最后对压实的沥青路面进行喷水保养。本申请具有增强沥青混合料的路面抗开裂性能的效果。
