The invention discloses a method for preparing a Kaipu seal coat by using steel slag, which comprises the following steps: 1) cleaning and blowing off sundries on a base layer, and repairing the base layer; (2) fast-breaking high-solid-content emulsified asphalt and steel slag are sprayed synchronously, the emulsified asphalt is ground after being subjected to primary demulsification, and a steel slag gravel sealing layer is formed after forming; the solid content of the high-solid-content emulsified asphalt is greater than or equal to 65%; (3) adsorbing pumice, spraying a fog sealing layer on the steel slag gravel sealing layer, and demulsifying and forming the fog sealing layer; and (3) micro-surfacing or slurry sealing is conducted on the steel slag and gravel sealing layer with graystone as aggregate, a composite surface wearing layer is formed, and the Kepu sealing layer is obtained after forming. The Kepp seal coat is prepared from the steel slag, the hardness and wear resistance of the steel slag are fully utilized, the wear resistance of the pavement is greatly improved, the water sealing coefficient is improved, and the service life of the road is prolonged; the steel slag resource is recycled, waste is turned into wealth, and huge economic benefits are created.
本发明公开了一种用钢渣制备开普封层的方法，1)将基层的杂物清扫吹净，修补基层；2)同步喷洒快裂型高固含量乳化沥青和钢渣，乳化沥青初步破乳后进行碾压，成型后形成钢渣碎石封层；所述高固含量乳化沥青的固含量≥65％；3)吸附浮石，在钢渣碎石封层上喷洒雾封层，雾封层破乳成型；3)以玄武石作为骨料在钢渣碎石封层上进行微表处或稀浆封层，形成复合表面磨耗层，成型后获得开普封层。利用钢渣制备开普封层，充分利用钢渣的硬度及耐磨性，极大程度的提高路面耐磨性能，提高封水系数，增加道路寿命；将钢渣资源再利用、变废为宝，创造巨大的经济效益。
