| Abstract: | Based on the analysis of important effects of the pavement performance,a pavement performance combining method is proposed with neural network and Markov process.The model combining forms are discussed and the parameters optimization is suggested.Then using actual survey datum of a highway in Henan,experiments are studied and the results show that the proposed combining model is capable to improve pavement performance forecasting by choosing suitable combining forms and their parameters. |
