**7. Conclusions**

Based on the measured value of the rutting model with the pavement structure represented by the RIOHTrack full-scale test track, the rutting prediction model in China's Specifications is analyzed. Moreover, the following conclusions are drawn:


In this research, a local correction method of the rutting prediction model is proposed. Although this method is discussed for the rutting model in China's Specification, the basic principle of this method is to introduce correction coefficients. The constant terms, exponential terms of loads, and environment parameters in the model are modified respectively to improve the prediction accuracy of the model. The ideas and methods of this model correction also have a certain reference value for the correction of rutting models in other regions. When the accuracy of the estimation of the existing rutting models in other regions is poor, you can refer to this research's method to make local correction on key parameters to improve accuracy and enhance regional applicability. In addition, the RIOHTrack fullscale pavement test track, which this research is based on, is still carrying out accelerated loading tests. It is expected that by the end of 2022, cumulative ESALs will reach 65 million ESALs. The related work in this research will also carry out further tracking research and analysis with the update of long-term observation data of rutting.
