This paper systematically reviews the differences in the criteria for determining cracks, potholes, and subsidence in North China, East China, and Southwest China, and delves into the underlying causes from three dimensions: management entity positioning, heterogeneity of detection technologies, and conflicts in classification logic. In response to the aforementioned issues, a "four-stage collaborative standard framework", a cross-method fusion mechanism, and a dynamic monitoring and updating system are proposed, establishing a standardized path encompassing "formulation - implementation - feedback". The research findings provide a systematic approach and theoretical support for enhancing the scientificity, adaptability, and engineering executability of disease identification standards.
