With the gradual improvement of highway network in China, it is necessary to study on the maintenance sequence of network-level pavement, that is to invest limited maintenance funds in the road sections where maintenance is most in need in order to maximize benefits. In this paper, the core index of network pavement maintenance sequence is considered comprehensively, and the index system is established, and then the weight of each index is determined by using the reciprocal matrix based on preference information. Finally, complex element extension method is used to establish matter-element analysis model to analyze the asphalt pavement maintenance sequence of highway network. The results show that the study of network pavement maintenance sequence can be used to guide the formulation of pavement maintenance planning, and it is of great significance to network pavement maintenance management and scientific decision-making in China.
