Research on Common Road Damage Problems in Road Engineering Applications

Abstract

As a core component of transportation infrastructure, the service status of road engineering has a direct impact on traffic safety and operational efficiency. This paper focuses on the frequent damage problems in road engineering applications. Through literature research and data analysis, it systematically sorts out three major types of common diseases: structural damage, functional damage, and auxiliary facility damage. The research indicates that overloaded traffic, construc-tion quality defects, environmental degradation, and delayed maintenance are the primary factors contributing to these issues. Among them, the incidence of dis-eases such as cracks, ruts, and uneven settlement accounts for more than 80%. For every 5% increase in the proportion of heavy-duty vehicles, the service life of the pavement can be shortened by 12%-18%. Damage problems not only cause annual economic losses of hundreds of billions of yuan but also directly or indirectly induce 17.3% of road traffic accidents. By analyzing the formation mecha-nisms and influence laws of various types of damage, this paper provides theoretical support for optimizing road engineering design, construction control, and the formulation of maintenance strategies, which is of great practical significance for extending road service life and enhancing infrastructure resilience.
