0对于高速公路沥青路面的养护工作中英文分析对于高速公路沥青路面的养护工作中英文分析Analysis of the maintenance work of Expressway Asphalt Pavement对于高速公路沥青路面的养护工作具有重要的意义，养护工作不但可以减少公路投入、降低资源消耗，还可以延长高速公路的使用寿命除此之外，高速公路的养护与管理也是我国现阶段公路事业发展的关键Has an important significance for the maintenance work of expressway asphalt pavement, maintenance work can not only decrease the highway investment, reduce the consumption of resources, but also prolong the service life of highway. In addition, the key maintenance and management of freeway is the present stage of our country highway development.一、高速公路路面养护的重要性 One, the importance of expressway pavement maintenance为了保证高速公路的正常使用，消除公路病害、延长高速公路的使用寿命，对高速公路的养护便成了现时期的高速公路建设的主要任务。

因为在高速公路的施工过程中如果不能确保路面质量，那么路况问题一突出道路通行就会受大很大程度的影响高速公路养护质量如何直接以对路面的养护工作质量为依据和标准所以对于高速公路路面的养护工作在当前显得尤其重要 In order to ensure normal use of the highway, the elimination of highway disease, prolong the service life of highway, the highway maintenance has become the main task of highway construction is now in the period of. Because in the construction process of Expressway if cannot ensure the pavement quality, so the traffic problem prominent traffic will be affected by a large extent. Highway maintenance quality directly to the quality of pavement maintenance work as the basis and standard. So for the maintenance work of expressway pavement is especially important in the current is. 目前我国已经建成的高速公路 75%左右是半刚性基层高级沥青混凝土面层结构，这些高速公路建成后，受交通量迅速增长、车辆大型化、超载严重、行驶渠道化及水损坏等影响，路面发生了不同程度的早期损坏，导致养护任务艰巨。

《公路养护技术规范》明确提出：公路养护工作必须贯彻“预防为主，防治结合”的方针，而现实是高速公路养护管理不足，对病害处理不及时，预防性养护处理不到位；加上交通量增长迅速、早期施工缺陷、温度变化、水的影响等，造成多数高速公路未到设计年限，路面已严重破坏，大修提前高速公路实施路面预防性养护，能及时修复路面微小病害，不致产生严重损伤，从而减少铣刨、翻修次数，节省大修费用，并延长路面使用寿命，保持路面良好的服务状态所以研究开发高速公路沥青路面预防性养护技术与管理模式，实施路面预防性养护管理是我国高速公路发展的迫切需要At present, about 75% of China's expressway has been completed is semi-rigid advanced asphalt concrete surface layer structure, the expressway was completed, by the rapid growth of traffic volume, vehicle scale, serious overload, channel running and water damage of pavement, early damage in varying degrees, resulting in maintenance task. In addition, with the increase of time and use the highway mileage extension will bring the pavement continuous damage, maintenance quantity will be more and more. Can be expected in the future for a period of time, our country highway by the construction, simultaneously to the construction and maintenance, and gradually to the maintenance. “ Technical specifications “ highway maintenance made clear: the highway maintenance work must implement the “prevention first, combining prevention with control “ policy, but the reality is lack of expressway maintenance management, not timely for disease treatment, preventive maintenance is not in place; and rapid traffic growth, early construction defects, change of temperature, the influence of water, cause most highway before the design life, the road has been severely damaged, overhaul advance. The expressway pavement preventive maintenance, timely repair pavement small disease, does not cause serious damage, thereby reducing milling, revision number, save the overhaul cost, and prolongs the service life of the pavement surface, keep good service state. So the research and development of expressway asphalt pavement preventive maintenance and management mode, the implementation of pavement preventive maintenance management is an urgent need for the development of China's freeway.二、路面病害维修的基本方法 Two basic approaches, pavement repair.因为高速公路沥青路面病害程度或者病害原因不同，所以说对于高速公路路面病害维护的方法也是不尽相同。

为此，笔者结合实际工作对路面病害维修的基本方法进行了以下阐述，主要包括对局部的养护、罩面以及翻修三个方面Because of the degree of disease of asphalt pavement or disease are different, so the maintenance methods of expressway pavement disease is not the same. Therefore, the author combines the basic method for the repair of pavement practical work for the following elaboration, mainly including the local maintenance and overhaul, covering three aspects.首先对于局部的养护工作的实施对于局部养护工作的实施主要从沥青路面裂缝的维修、冻胀与翻浆的维修、沥青路面车辙的维修以及桥面铺装损坏的维修四个方面进行相关分析 第一，对于路面裂缝的维修工作，现在的这种病害现象已不多见，早期的公路裂缝病害多源于温度裂缝、半刚性基层反射裂缝和基层强度不足引起的网状裂缝。

具体处理要求，对于裂缝宽度在 5 厘米以内的横向裂缝要及时地灌入热沥青而对于超过 5 厘米要先进行机械开槽，继而在进行细粒式沥青混合料进行填充和捣实对于出现的网状裂缝应将沥青表面铣刨或拉毛，再加铺一层沥青混凝土上封层The first part of the implementation of the maintenance work. For local maintenance work is mainly from the implementation of asphalt pavement crack repair, frost heave and frost boiling repair, the repair of asphalt pavement rutting and bridge deck pavement damage repair four aspects to carry on the related analysis. First, for the pavement crack repair work, the disease is now already did not see more, reticulate crack of road cracks caused by multi-source early temperature cracks, reflective crack in the semi-rigid base and base strength is insufficient. Specific treatment requirements, for crack width in the tr。
