Preparation method of microcapsule re-excited durable pavement crack pouring adhesive

The invention discloses a preparation method of a microcapsule re-excitation durable pavement crack pouring adhesive, and belongs to the technical field of pavement engineering crack repair. In orderto solve the problem of short service life of the crack pouring adhesive, the method comprises the following steps: doping a temperature-sensitive microcapsule into a crack pouring adhesive to preparea microencapsulated crack pouring adhesive, wherein a microcapsule wall material is an excitable material with the temperature of 200 DEG C or above, and a core material is light oil in asphalt regeneration. According to the invention, the asphalt material can be recycled; after the crack pouring adhesive is used for a certain time, the failure reaches a certain degree, an excitation mechanism can be adopted, the asphalt is regenerated to recover the function of the crack pouring adhesive, the pavement use performance requirement is continuously met, and multiple excitations can be performed,so that the service life o
