The urban traffic situation has become increasingly complex in recent years, and the current performance evaluation code for urban road asphalt pavement is no longer applicable to the actual situation of roads, which led to a lack of comprehensive analysis to the proposed schemes of pavement maintenance. Firstly, this paper combines the Attribute hierarchical model and the Entropy weight method. Secondly, the Pavement Structure Strength Index and Skidding resistance Index are incorporated into the comprehensive evaluation to reconstruct the weights of each evaluation index. Thus, a new evaluation model of asphalt pavement is established. As the example shows that the current evaluation model is hard to correctly evaluate the road sections with the structural strength of the subgrade does not meet the standard. But the new evaluation model is effective and valuable for evaluating the current performance of urban road asphalt pavement.
