Research on pavement performance prediction and intelligent maintenance based on grey prediction model
CHEN Xiao-jiang
Abstract：This paper builds a prediction model based on grey system theory to predict the performance of urban pavement,and combines grey relational degree and analytic hierarchy process to realize the intelligent maintenance decision of urban pavement.The results show that the maximum errors of the model in the pavement condition index(PCI)and pavement driving quality index(RQI)are 0.68 and 0.74,respectively,and the prediction accuracy is 99.54%and 99.49%,respectively.Among the total ranking weights,the weight of the thin layer covering measures was the largest,which was 0.397 7.The prediction model can accurately predict the performance of pavement and provide a reference for urban pavement performance prediction and intelligent maintenance.
