关于高速公路沥青路面的养护工作中英文分析Word文件下载.docx

1、因为在高速公路的施工进程中若是不能确保路面质量，那么路况问题一突出道路通行就会受大专门大程度的阻碍。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。因此关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

2、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 f

3、or 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，受交通量迅速增加、车辆大型化、超载严峻、行驶渠道化及水损坏等阻碍，路面发生了不同程度的初期损坏，致使养护任务艰巨。另外，随着高速公路里程的增加和利历时刻的延长必然会带来路面不断的损坏，养护工程量将愈来愈大。能够估量尔后一个时期，我国高速公路将由建设为主，转为建设与养护并举，并慢慢以养护为主。公路养护技术标准明确提出：公路养护工

4、作必需贯彻“预防为主，防治结合”的方针，而现实是高速公路养护治理不足，对病害处置不及时，预防性养护处置不到位；加上交通量增加迅速、初期施工缺点、温度转变、水的阻碍等，造成多数高速公路未到设计年限，路面已严峻破坏，大修提早。高速公路实施路面预防性养护，能及时修复路面微小病害，不致产生严峻损伤，从而减少铣刨、翻修次数，节省大修费用，并延长路面利用寿命，维持路面良好的效劳状态。因此研究开发高速公路沥青路面预防性养护技术与治理模式，实施路面预防性养护治理是我国高速公路进展的迫切需要。At present, about 75% of Chinas expressway has been complete

5、d 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

6、 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 graduall

7、y 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 mainte

8、nance 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 di

9、sease, 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 technology and management mod

10、e, the implementation of pavement preventive maintenance management is an urgent need for the development of Chinas freeway.二、路面病害维修的大体方式Two basic approaches, pavement repair.因为高速公路沥青路面病害程度或病害缘故不同，因此说关于高速公路路面病害保护的方式也是不尽相同。为此，笔者结合实际工作对路面病害维修的大体方式进行了以下论述，要紧包括对局部的养护、罩面和翻修三个方面。Because of the degree of d

11、isease 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

12、, covering three aspects.第一关于局部的养护工作的实施。关于局部养护工作的实施要紧从沥青路面裂痕的维修、冻胀与翻浆的维修、沥青路面车辙的维修和桥面铺装损坏的维修四个方面进行相关分析。第一，关于路面裂痕的维修工作，此刻的这种病害现象已不多见，初期的公路裂痕病害多源于温度裂痕、半刚性基层反射裂痕和基层强度不足引发的网状裂痕。具体处置要求，关于裂痕宽度在5厘米之内的横向裂痕要及时地灌入热沥青。而关于超过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。关于显现的网状裂痕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 th

13、e 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.

14、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

15、transverse cracks within 5 cm to timely poured into the hot asphalt. For more than 5 cm to mechanical grooving, then in the fine asphalt mixture filling and compaction. The reticular cracks should be asphalt surface milling or napping, plus a layer of asphalt concrete layer.第二，关于冻胀与翻浆的维修。关于容易发生在开山路堑

16、段的冻胀现象，要先将路基下部设置纵向或横向盲沟，然后再进行路面的处置工作。若是关于高速公路显现的翻浆现象，要将原路面挖到路基顶部，再填充砂砾垫层，重做水泥稳固砂砾，最后再做混凝土面层的铺筑。Second, the frost heave and frost boiling repair. For those in the frost heaving and open road section, put the subgrade longitudinal or transverse blind ditch is arranged at the lower part, processing and

17、 then pavement. If the boiling phenomenon expressway, to the original pavement subgrade excavation to top, then filling gravel cushion, redo cement stabilized gravel, then do the concrete surface layer paving.第三，沥青路面车辙的维修。关于沥青路面显现的车辙现象必然要确信好是哪一种类型的车辙，什么缘故造成的车辙。关于不同的车辙采取的方法也不尽相同。关于路面基层强度不足而造成的车辙要先铣掉面

18、层，先从路面基层做起，然后再进行面层铺筑；若是路面车辙是因为表层磨损过度而造成的车辙，要先清除面层再进行铺筑沥青混凝土铺筑工作。Third, the rutting of asphalt pavement repair. The rutting of asphalt pavement appear to determine what type of rutting, what causes the rut. For different rut measures are not the same. For the lack of pavement strength caused by the r

19、ut to mill off the surface layer, the first from the surface of the grass-roots level, and then paving surface; if the pavement rutting is because the surface wear caused by excessive rutting, the first clear the surface layer of paving asphalt concrete paving work.第四，关于桥面铺装损坏的维修。桥面显现损坏要紧有两种情形：一个是只是

20、沥青面层损坏，而在面层下的混凝土尚好。这时就需要将沥青面层铣掉，露出水泥混凝土。然后再喷乳化沥青，最后进行混凝土铺筑。另一个是沥青面层损坏、层下的混凝土也损坏了，这时就需要先将混凝土进行处置，关于损坏面积小的能够进行局部修复，而关于损坏面积比较严峻的那么要进行从头进行混凝土铺装的工作。Fourth, for the bridge deck pavement damage repair. Bridge damage occurs mainly to have two kind of situations: one is just the asphalt surface layer damage,

21、 but under the surface layer of concrete is good. Then you will need to asphalt pavement milling off, exposing cement concrete. And then sprayed emulsified asphalt concrete paving, finally. Another is the asphalt surface layer damage, the concrete is damaged, then you need to be concrete processing,

22、 for the damaged area can be small to local repair, the damaged area is more serious is to concrete pavement work.第二是罩面。高速公路路面罩面要紧为了排除破损、改善路面的平整度和恢复抗滑性能，以前采纳抗滑表层AK13A 或 AK16A 型，近几年，随着SMA 路面结构技术的日臻成熟，SMA 是最为理想的面层结构，一样罩面的厚度宜在45cm，一样不得小于4cm。路用沥青最好利用 SBS 改性沥青。The second is the cover. Highway pavement ov

23、erlay is mainly in order to eliminate the damage, improve the surface smoothness and recovery of skid resistance performance, before the anti-slide surface AK - 13A or AK - 16A, in recent years, along with the technology of SMA pavement structure is becoming more and more mature, SMA is the most ide

24、al surface layer structure, the thickness of the surface should be in the 4 general hood to 5cm, generally not less than 4cm. Asphalt with the best use of SBS modified asphalt. 最后翻修。当高速公路路面破损严峻，采纳罩面的养护方式不能使路面恢复良好利用状态时，或路面承载力严峻不足时，那么应进行翻修。翻修需重做垫层和基层，从头铺设面层。The last revision. When the pavement is seri

25、ously damaged, the overlay curing method can not make good use of pavement state, or the road carrying capacity is seriously insufficient, should be renovated. Revision required redo cushion and base, laying back surface layer.三、路面维修施工方式Methods three, pavement repair and construction第一,依照维修设计进行施工前的预

26、备工作。关于维修设计前的预备工作是路面维修的前提，预备工作做的好才能保证路面维修施工顺利开展。关于施工前的预备工作要紧包括对在施工中会用到的材料进行技术指标检测和相关的调查实验，检测完毕以后不符合要求的要先行淘汰，而关于符合要求的材料投入到施工利用当中；关于复核维修路段内的病害情形，需要对路面的标高进行测量，还要测量会用到的其它数据信息；而关于施工进程中会用到的机械、工具也要在施工前做好全面检查工作，保证它们的性能良好，并保证它们的正常利用状态。除此之外还要保证机械的数量必要知足施工需要，重要的机械还要有备用设备。Firstly, according to the repair design

27、for the preparatory work before construction. Preparation for repair before the design is a prerequisite for pavement repair, ready to do a good job in order to ensure the pavement repair construction smoothly. For the preparation work before construction mainly includes the investigation test techn

28、ology index and related to the construction used in the detection of materials, finished do not meet the requirements to be eliminated, and to meet the requirements of the material into the construction used for diseases; review dimensional road section in the elevation of the pavement, need measure

29、ment data, other information and measurement will be used; and for the construction process will be used in the machinery, tools to do a comprehensive inspection work before construction, to ensure that their performance is good, and to ensure their normal state. In addition to guarantee the quantit

30、y necessary to meet the need of construction, important machinery and spare equipment.第二,路面的铣刨。其一是施工放样。依照路面的损害情形和设计的高程确信铣刨深度，在路面上做好标记，以保证铣刨后具有良好的“平整度”。其二是铣刨废料要运出场外，不得随意抛弃污染环境。第三,关于路面基层的施工。一方面需要重做基层的路段Secondly, milling surface. One is the construction lofting. According to the pavement damage and the design is determined by the height of the milling depth, mark on the road, in order to ensure the smoothness of the good has milling after . The second is to carry out the milling waste, not free to discard the pollution
