摘　　要：公路网络的建成并不意味着工作的结束,公路的长期维护才是更为艰巨的任务。在长时间的使用过程中,无论是地基、路面都会因疲劳强度的增加出现各种问题。其中,地基可能出现滑移、下沉等情况,而路面则可能出现翻浆、裂缝、破损。一旦地基和路面出现问题,轻则降低车辆的通行效率,重则会出现各种事故,带来各种损失。因此,必须对公路进行及时有效的维护处理。该文以公路沥青路面为例,对其按技术等级划分、按路面层次结构划分、按施工技术及材料划分。以公路沥青路面为研究对象,对其进行质量分析,使用PCI和RQI两类指标,进而对公路沥青路面质量的影响因素进行分析和分类,形成裂缝影响、松散影响和其他影响的分类标准。最后,针对PCI和RQI指标的不同组合所反映出的公路沥青路面质量,给出小修、中修、大修和日常维护的不同方式,并给出一种基于决策树模型的养护方案。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.
