【摘要】：自我国进入21世纪以来,我国高速公路迅猛发展,截至2014年底,我国高速公路总里程突破10.8万公里,仅次于美国,位居世界第二[1]。另外,在未来十年内,我国高速公路将从交通建设期进入养护管理期,目前国内高速公路路面养护工作重要的课题是如何针对各种路面病害进行对应的养护,目的在于达到最优的效果。另外,据不完全统计,在我国已建成的高等级公路路面中,约有80%为沥青路面[2]。因此,沥青路面的养护已经成为公路路面养护的重中之重。本文依托大量的国内外文献回顾和对现有高速公路养护管理单位实地调研对国内外沥青路面典型病害养护技术进行了较为深入的研究。首先对现有的沥青路面病害进行了分析,简述了沥青路面的各种病害类型,介绍了病害间的直观区分方式(包括外观,出现的地点等),分析了各种病害对于路面行车条件,路面寿命,路面养护成本等因素的影响及其区别,初步阐述了现阶段沥青路面的病害情况,并归纳出了裂缝、车辙、坑槽为现阶段沥青路面的典型病害类型;其次,针对归纳得的三种种典型病害类型分别进行分析,先分别简述了三种病害的具体成因,在针对不同的导致因素对相应的养护技术进行了描述以及对比,提出国内养护技术的不足并最终汇总成建议表述;最后,总结全文,对沥青路面养护技术的现状进行了展望。
[Abstract]:Since China entered the 21st century, the expressway of our country has developed rapidly. By the end of 2014, the total mileage of expressway in our country has exceeded 108000 kilometers, which is second only to the United States and ranks second in the world [1]. In addition, in the next ten years, the expressway in our country will go from the period of traffic construction to the period of maintenance and management. At present, the important task of the domestic expressway pavement maintenance work is how to carry out the corresponding maintenance for various pavement diseases. The aim is to achieve optimal results. In addition, according to incomplete statistics, about 80% of the high grade highway pavement built in our country is asphalt pavement [2]. Therefore, the maintenance of asphalt pavement has become the most important maintenance of highway pavement. In this paper, based on a large number of domestic and foreign literature review and existing highway maintenance and management units field research on the domestic and foreign asphalt pavement typical disease maintenance technology has carried on the comparatively thorough research. First of all, the existing asphalt pavement diseases are analyzed, the types of asphalt pavement diseases are briefly described, the visual differentiation between the diseases (including appearance, location and so on) is introduced, and the driving conditions of various diseases for the pavement are analyzed. The influence and difference of pavement life, pavement maintenance cost and other factors are discussed in this paper, and the damage situation of asphalt pavement at present is preliminarily expounded, and cracks, ruts and potholes are concluded as typical disease types of asphalt pavement at the present stage; secondly, Based on the analysis of the three typical disease types, the specific causes of the three diseases are briefly described, and the corresponding maintenance techniques are described and compared in the light of different factors. The deficiency of domestic maintenance technology is put forward and finally summarized into a proposal. Finally, the paper summarizes the full text and looks forward to the present situation of asphalt pavement maintenance technology.
