I基于淅川县东环路项目分析二级公路沥青混凝土路面常见病害原因及应对措施摘要在中国，高速公路建设非常迅速，不管是在国家经济方面，还是在整个社会发展方面，都起着非常重要的作用。由于沥青路在全国范围内大面积普及，随之而来带来了诸多问题，最常见的问题就是怎样对沥青路进行有效的维护，同时它也是比较困难的一个问题。在沥青路最开始投入使用的时候，人们会比较注意它带来的病害，比如可能发生裂缝的现象或者是泛油的现象等等。这些问题都比较频繁的出现在公路质量问题中，从而使公路不能够被正常使用，因此，养护公路这一项任务就面临了更严峻的考验。这篇文章主要分析了到底哪些因素造成了疾病的产生，并且结合实际情况提出了相应的预防措施和处理方法，并以淅川县东环路沥青路面的检测状况为实例进行了分析，得到主要结论为：沥青路面虽不可避免的会产生路面病害，但可通过合理设计路面结构形式，保证压实质量和施工质量，并加强沥青路面的养护等方式能有效的改善沥青路面的抵抗性能和耐久性。关键词：沥青路面；早期病害；裂缝；防治措施有II3AbstractInChina,highwayconstructionisveryfastandplaysavitalroleinnationaleconomicandsocialdevelopment.However,withthecontinuousconstructionofasphaltpavement,themaintenanceofasphaltpavementhasbecomethefocusanddifficultproblemofhighwaymaintenance.Asphaltpavementwillcauseseriousdamageattheearlystageofoperation,whichmakestheearlydiseasesofasphaltpavementmoreandmoreattractingpeople'sattention.Atpresent,themostcommonearlydiseasesofasphaltconcretepavementincludecracks,ruttingandoilspreading.Thesediseasesarebasicallycommondiseasesofhighwayengineeringquality,whichseriouslythreatenthenormaluseofnewhighwaysandposemoreseverechallengestohighwaymaintenance.Thispaperanalyzesthecausesoftheabovecommondiseases,andputsforwardthecorrespondingpreventionmeasuresandtreatmentmethodsaccordingtotheactualsituation,andanalyzesthetestingsituationoftheasphaltpavementintheEastRingRoadofXichuanCountyasanexample.Themainconclusionisthattheasphaltpavementwillinevitablyproducepavementdiseases,buttheroadcanberationallydesigned.Thesurfacestructureform,ensuringthecompactionqualityandconstructionquality,andstrengtheningthemaintenanceofasphaltpavementcaneffectivelyimprovetheresistanceperformanceanddurabilityoftheasphaltpavement.KeyWords:asphaltpavement;earlydiseases;cracks;preventivemeasures4目录1绪论.........................................................................................................................................................21.1项目研究背景和目的................................................................................................................21.1.1研究背景........................................................................................................................21.1.2研究目的........................................................................................................................21.2国内外研究现状........................................................................................................................31.2.1国外研究现状................................................................................................................31.2.2国内的研究现状............................................................................................................31.3研究的内容和方法....................................................................................................................51.3.1研究内容...............................................................
