In order to make the assistant decision of airport pavement management more accurate and meet the requirements of intelligence，the existing network-level decision making algorithms need to be improved. Based on the concept of information entropy，we present a decision tree model of civil airport cement pavement maintenance plan. The model test and evaluation results show that the model has high accuracy， cross-validation and self-correcting ability. We take Shanghai Pudong International Airport pavement management system as an example. Compared with traditional models，the decision tree model is proved to encompass multi-factors， like pavement performance， structural performance and subjective factors of management needs. The results demosnstrate that the proposed model is more fit the engineering in practice. [ABSTRACT FROM AUTHOR]
