Abstract
The completion of the highway network does not mean the end of the work,the long-term maintenance of highways is a more arduous task.During long-term use,both the foundation and road surface will experience various problems due to the increase in fatigue strength.Among them,the foundation may experience slippage,subsidence,and other situations,while the road surface may experience frost heave,cracks,and damage.Once there are problems with the foundation and road surface,it can reduce the efficiency of vehicle traffic and cause various accidents and losses.Therefore,it is necessary to carry out timely and effective maintenance and treatment of highways.In this article,taking highway asphalt pavement as an example,it is classified according to technical grade,pavement hierarchy structure,construction technology,and materials.Taking highway asphalt pavement as the research object,quality analysis was conducted using two types of indicators,PCI and RQI.Furthermore,the factors affecting the quality of asphalt pavement on highways were analyzed and classified,forming classification standards for crack impact,loose impact,and other impacts.Finally,different methods of minor,medium,and major repairs were proposed for the quality of highway asphalt pavement reflected by different combinations of PCI and RQI indicators,and a maintenance plan based on a decision tree model was proposed.关键词
