Abstract:

Fibers exhibit excellent strength and deformation capacity. When incorporated fiber into micro-surfacing mixtures, they can serve as reinforcement and provide waterproofing functions, thereby addressing issues such as easy cracking and poor durability in traditional micro-surfacing, and significantly enhancing the service quality of micro-surfacing. In this paper, the composition and proportion of fiber-modified micro-surfacing materials were systematically reviewed. The enhancement mechanisms of physical and chemical surface modification methods on fiber dispersion and interfacial bonding were revealed. The effects of fiber type, content, and binder type on improving the construction performance, abrasion resistance, water damage resistance, and rutting resistance of micro-surfacing were comparatively evaluated. Additionally, the limitations of existing evaluation methods for low-temperature crack resistance were analyzed. The optimal fiber type and content for fiber micro-surfacing were recommended. The performance enhancement mechanisms of fiber-modified micro-surfacing were elucidated. Finally, an outlook on future research trends in fiber micro-surfacing was provided. The aim is to promote the high-quality development and application of fiber-modified micro-surfacing.
