| description | To effectively evaluate the performance improvement of cement pavement in seasonal frost regions, the typical diseases of cement concrete pavements in seasonal frost regions are proposed through the analysis of measured data, and the influence factors of pavement performance mutation value in seasonal frost regions is determined, the application conditions of the model are obtained by the response surface test method; the road performance improvement model is established by the regression analysis method, and the goodness of fit and significance state of the model were tested, and the validity of the model was verified by comparing with the evaluation results of the existing model. The results show that: broken slabs, staggered platforms, cracks, exposed aggregates, broken corners and potholes are typical diseases of cement concrete pavement in seasonal frost regions; the mutation value of pavement performance is most sensitive to the impact of road damage index, running quality index and anti-skid performance index before pre-maintenance, which under pre-curing conditions. The evaluation effect of the model for improving the performance of cement concrete pavement in seasonal frost regions is good, and the interpretable part of the improvement of pavement performance by the model is 99.2%; the fit of the improved evaluation value and the measured value is 0.991, and the model high fit. The evaluation effect of the proposed model is better than the existing model, and the determination of the model is of great significance to the pre-maintenance of cement concrete pavement. |
