Asphalt Pavement Evaluation Based on Matter Element Model

Pavement performance evaluation is one of the most important problems in pavement management system. In traditional methods for pavement performance evaluation, the weights of evaluation indexes are hard to determine and mainly depended on subjective judgment. The paper get the evaluation indexes by employing the concept of entropy and the weights of the evaluation indexes are obtained from surveying data. The matter element model for pavement evaluation is established. By calculating the dependence degree of the matter element model, the pavement evaluation is obtained. The results show that the matter element model has good ability to evaluate the pavement performance.
