[0002] Asphalt pavements are prone to microcracks under long-term traffic loads and environmental conditions. If these microcracks are not addressed promptly, they can further develop into macrocracks under stress concentration, providing pathways for moisture to enter the pavement and leading to problems such as pumping, frost heaving, and loosening. Focusing on this issue, microcapsule self-healing pavement technology has come into focus. Incorporating microcapsules into asphalt pavements can enhance their self-healing properties to a certain extent, thereby repairing microcracks within the asphalt. With the development and application of microcapsule technology, how to prepare microcapsules simply, efficiently, environmentally friendly, and cost-effectively for practical road engineering has become an unavoidable problem.

[0003] Current microcapsule preparation technologies include in-situ polymerization, interfacial polymerization, and sol-gel methods. Among these, in-situ polymerization is widely used due to its simplicity, high efficiency, high encapsulation rate, and significant economic benefits. However, traditional in-situ polymerization methods require various instruments such as high-speed shear emulsifiers and constant-temperature magnetic stirrers. The dispersed nature of these instruments leads to cumbersome and complex experimental procedures, significant material waste, long operation times, and low efficiency.
