Asphalt Pavement Performance Prediction Model Based on Gray System Theory

Based on the method of the gray system theory,the prediction models of pavement structure strength index,pavement conditions index and the pavement roughness are obtained respectively.The prediction models are validated and modified through the actual road test data,and compared with the traditional model of regression analysis.The results show that for predicting such discrete target value of pavement surface condition,the gray prediction method can improve the accuracy,and meet the requirements of pavement performance prediction.
