Road repairing asphalt mixture and construction method thereof
The invention relates to the technical field of road repairing, in particular to a road repairing asphalt mixture and a construction method thereof. The road repairing asphalt mixture is prepared from epoxy modified asphalt, acrylic resin, cement, water, carbon fibers, porous aggregate, small repairing balls and sodium bentonite. The epoxy modified asphalt and the acrylic resin in the mixture are subjected to hot pressing and then are mutually crosslinked to form an IPN network, the pavement performance and the strength of the mixture can be improved, in addition, after cracks are generated in the mixture, the dry alkyd resin filled in the repairing small balls can permeate into the cracks, reacts with oxygen and then is gradually crosslinked and cured, the cracks are bonded and repaired, therefore, the service life of the mixture is prolonged, practical significance and popularization value are achieved, and it is expected that good economic benefits can be generated.
本发明涉及道路修补技术领域，具体为一种道路修补沥青混合料及其施工方法，其成分包括环氧改性沥青、丙烯酸树脂、水泥、水、碳纤维、多孔骨料、修补小球和钠基膨润土，本发明提供了一种道路修补沥青混合料，混合料内的环氧改性沥青与丙烯酸树脂热压后相互交联交联形成IPN网络，能够提高混合料的路用性能和强度，此外当混合料产生裂隙后修复小球内填充的干性醇酸树脂能够渗入缝隙内，与氧气反应后逐渐交联、固化，对裂隙进行粘结、修复，从而提高混合料的使用寿命，具有实用意义和推广价值，预期能够产生良好的经济效益。
