摘　　要：为直观掌握公路沥青路面的性能变化情况,使高速公路的养护施工方案具备明确的参考信息,对沥青路面的技术状况做出合理科学的预测,该文针对常见的高速公路沥青路面病害特征进行总结,同时以昭通市农村公路养护工程项目为例采用马尔可夫模型进行预测和分析。最终得出,基于灰色马尔可夫模型对昭通市农村公路路面技术状况的预测指标与公路实际运行状态相符合,经过相应养护过后,路面性能指标得到显著优化。因此,通过对高速公路路面性能预测模型进行构建,能够较为直观地针对沥青路面性能指标做出评价、分析与预测,同时结合实际给出相应的养护方案建议,对提升高速公路运行安全性能,延长高速公路运行寿命具有关键性意义,值得推广和运用。In order to intuitively grasp the performance changes of highway asphalt pavement,make the expressway maintenance and construction plan have clear reference information,and make a reasonable and scientific prediction of the technical status of asphalt pavement,this paper summarizes the common disease characteristics of expressway asphalt pavement,and uses Markov model to predict and analyze the rural highway maintenance project in Zhaotong City.Finally,it is concluded that the prediction index of the technical status of the rural highway pavement in Zhaotong based on the Markov model is consistent with the actual operation state of the highway.After the corresponding maintenance,the pavement performance index has been significantly optimized.Therefore,through the construction of expressway pavement performance prediction model,the performance index of asphalt pavement can be evaluated,analyzed and predicted intuitively,and the corresponding maintenance scheme suggestions are given in combination with practice.It is of key significance to improve the safety performance of expressway operation and prolong the service life of expressway,which is worth popularizing and applying.
