Pavement Performance Prediction Model for Asphalt Pavement

There are many types of models for prediction pavement performance. In order to choosing a more reasonable model,the prediction results and applicability are discussed of sigmoid model,multinomial model,exponential model and Markov probability model with real pavement data in this paper. The results show that each model has some applicability and limitations,while sigmoid model presents better general prediction ability,and it can be used conveniently and has more universal applicability. The results are significant for choosing prediction models of pavement performance and the decision-making of pavement maintenance.
