Microcapsule preparation method for automatically repairing initial cracks of pavement and repairing method

The invention provides a preparation method of microcapsules for automatically repairing initial cracks of a pavement and a repairing method. The method comprises the following steps: preparing raw materials, mixing and reacting, adding formaldehyde, layering and drying, so that the prepared microcapsules are applied to the pavement. When cracks appear on the pavement, the capsule wall of the microcapsule can be broken, the internal repairing material is released, automatic repairing is achieved, the microcapsule is small in size and can be filled into the tiny cracks of the pavement, the capsule wall material is easy to break, the repairing quality is stable and reliable, the bearing capacity of the pavement can be effectively improved, and the service life of the pavement can be effectively prolonged. The method is simple and easy to implement, and can be widely applied to various types of pavement repair projects. 本发明提供了一种自动修复路面初期裂缝的微胶囊制备方法和修复方法，该方法包括准备原料、混合反应、加入甲醛、分层和干燥，以吸将制备好的微胶囊应用到路面上。当路面出现裂缝时，微胶囊的囊壁会破裂
