【摘要】 随着城市化进展的加快，我国很多城市都在大范围的扩张，因此很多城镇都逐渐变成城区乃至中心区。同时大量的城镇道路、地方公路需要经过改造变成城市道路，其中加铺沥青面层具有工程投资少、施工工期短、对交通影响少等优点，因此是旧水泥砼路面加铺沥青面层成为最常用的改造施工方法。但是由于养护工作缺乏针对性、及时性，导致改造后的沥青面层出现了不同程度病害，影响到行车安全性、舒适性，同时加大了养护维修经费的投入。因此有必要对旧水泥砼路面改造后沥青面层的病害类型进行调查和分析，查找病害原因和类型，分析改造项目的成败，对日后旧水泥砼道路的改造设计施工以及日常养护维修工作提供依据。本文首先探讨了旧水泥混凝土路面的病害调查和处治，同时介绍了沥青面层加铺的不同设计方法，然后通过城市道路状况指数对广州市南沙区工业四路等5条旧水泥砼道路改造后沥青面层病害的调查分析，计算各条调查道路的PCI数值，根据评价标准分析调查道路的病害主要类型和使用状况。论文探讨了旧水泥砼路面加铺沥青面层后的常见病害成因与防治，主要分析反射裂缝的成因与防治，探讨了土工布、玻纤格栅两种应力材料对反射裂缝的防治效果，为节约维修经费、延长道路使用年限提出合理建议。更多还原

【Abstract】 With the development of city to accelerate, our country a lot of city in the large-scaleexpansion, so many towns have gradually become urban area and center area. While a largenumber of urban road, where the road need after transformation into city road, the asphaltsurface layer has low engineering investment, construction period, traffic impact is little waitfor an advantage, it is the old cement concrete pavement asphalt overlay has become one ofthe most commonly used construction method.But due to lack of pertinence timeliness maintenance work, resulting in modified asphaltsurface layer appeared different degree of disease, affecting driving safety, comfort, andincrease the input of funds for maintenance and repair. So it is necessary to the old cementconcrete pavement reconstruction after asphalt pavement disease types of investigation andanalysis, find the disease reasons and types, analysis and transformation of the success orfailure of the project, for the old cement concrete road reconstruction design and constructionprovide a basis.This paper first discusses the old cement concrete pavement disease investigation andtreatment, and introduces the asphalt surface layer paving different design methods, and thenthrough the city road condition index on Guangzhou Nansha District Industrial Road four and5reconstruction of the old cement concrete road surface disease of asphalt after investigationand analysis, the survey of road PCI numerical calculation according to the analysis ofevaluation criteria, the main disease type and investigation on road usage. On the asphaltpavement common diseases causes and prevention, mainly analyzes the causes and preventionof reflection crack, in order to save repair funds, prolong road service life and put forwardreasonable suggestions.更多还原
