The invention discloses an asphalt pavement drilling and filling method, relates to the technical field of road building, and solves the problems of limitation in a drilling and filling technology in the prior art, difficulty in filling and compacting, excessive void ratio, unevenness in filling and incapability of ensuring the filling quality. The method comprises the following steps: manufacturing an asphalt mixture cylinder with the outer diameter smaller than the bore diameter of a drill hole and the thickness smaller than the thickness of an asphalt surface layer; putting a binding material and an asphalt mixture cylinder into the drill hole; and leveling the asphalt mixture cylinder. According to the method, filling can be conducted at any time, filling and compacting are simple, the porosity reaches the standard, filling is smooth, and the filling quality is guaranteed. 本申请公开了一种沥青路面钻孔填补方法，涉及筑路技术领域，解决了现有技术中钻孔填补技术中的局限性，以及填补压实困难，空隙率超标、填补不平整，填补质量不能保证的问题，该方法包括：制成外径小于钻孔孔径并且厚度小于沥青面层厚度的沥青混合料圆柱体；在钻孔中放入粘合物和沥青混合料
