Abstract:

The needs of maintenance and overlay for Portland cement concrete pavement(PCCP)were considered, the current Chinese technical specifications of cement concrete pavement maintenance were analyzed, and new evaluation index system and method were put forward. Pavement condition index(PCI), running quality index(RQI)and international friction index(IFI)were used to evaluate the functional performance of PCCP. The ratio of broken plate(DBL), the resilience modulus of base course, the load transferring capacity of the joint and the ratio of voided plate were used to evaluate the structural status of PCCP. A systematic pavement performance evaluation model was established by using fuzzy complex matter element method, and the fuzzy in classification of every index was considered. The weight of each index was determined by integrating analytic hierarchy process(AHP)method and entropy method to consider data objectivity and classification subjectivity. Computation result shows that the maximum correlation degree of evaluated pavement is 0.562 4 to the medium grade, and the second largest correlation degree is 0.319 4 to the poor grade, which means that the state of evaluated pavement is medium closely to poor grade according to the principle of maximum correlation, and is fit with the actual situation. The result indicates that the evaluation index system and method are feasible. 7 tabs, 10 refs.
