In recent years, our county, and village, the town built a large number of cement concrete pavement, needless to say, to improve the quality of our county highway pavement, enhance the capacity of highway disaster, improve road traffic conditions, improve the efficiency of the passenger and cargo transportation has played a positive role. 但是在重交通荷载、超载、水毁、其它自然环境等诸多外部因素的影响下，近期修建的水泥混凝土路面行车后不久就出现了许多不同程度的病害，导致路面的使用性能迅速下降，严重地影响了车辆快速、安全行驶，而且给养护和维修带来了巨大的压力。通过分析水毁原因，从设计、施工、养护三个环节提出防治办法。But in heavy traffic load, overload, waterlogging and other natural environment under the influence of many external factors, such as, the recent construction of cement concrete pavement appeared shortly after driving many of the different degree of disease, rapid drops in the performance of pavements, seriously affect the fast, safe driving vehicle, and to the maintenance and maintenance has brought great pressure. Analyzes reason of waterlogging, in three stages: from the design, construction, maintenance, prevention and control measures are put forward. 二、病害情况极其特点Second, disease is extremely characteristic 现举实例：某一路段全长5.26Km。路面结构为：18cm325水泥混凝土面层，20cm砂砾垫层，30cm土基处理。到目前为止出现路面病害如下：Now for instance: a road about 5.26 Km. 18 cm325 cement concrete pavement, pavement structure as follows: 20 cm gravel cushion, 30 cm soil foundation treatment. Pavement diseases so far are as follows: 1、路面病害特点1, the road surface plant disease characteristics （1）板块连续纵向裂缝较多(1) plate continuous longitudinal cracks （2）板块角隅断裂现象较多，断裂位置接缝材料剥落严重，且积水严重；(2) plate corner fracture is more, jointing material peeling off serious fracture, and the water is serious; （3）断板和严重破碎板较多，基本上都是在前两种病害基础上进一步发展而产生；(3) so and more severe crushing plate, are basically in the former two diseases on the basis of the further development and produce; （4）病害严重位置的接茬处沥青面层损坏较严重，由于积水和冻融作用使沥青砼松散。(4) the disease location of summer-planting asphalt layer damage more serious, due to water and asphalt concrete freeze-thaw action. 2、路面病害处治情况对照2, the pavement disease treatment situation （1）对混凝土板块凿除重新修复；(1) plate chisel in addition to the repair of concrete; （2）对裂缝板和板底脱空的板块进行压浆灌缝处治达到规范要求；(2) was carried out on the pavement cracks in the plate and the plate at the end of the plate grouting filling and seaming treatment meet the specification requirements; （3）在板块完好而积水严重位置处设置了横向排水体系。(3) in the plate is in good condition and serious water location set up horizontal drainage system. 3、水毁分析3, the waterlogging analysis 3.1 水泥混凝土路面结构层水的来源3.1 the source of the cement concrete pavement structure layer of water 水毁的防治，必须先了解积水产生原因，切断积水的产生渠道，及时处理、排除积水，增强对水的抵抗力，就能达到防治的目的，混凝土路面结构层水的来源主要有以下几方面：Prevention and control of waterlogging must first understand the causes of water cut of water channels, timely treatment, eliminate seeper, enhanced resistance to water, can achieve the purpose of prevention and control, the concrete pavement structure layer of water source has the following several aspects: （1）冬、春季节地下水位升高，路面设计标高较低；(1) the rise of underground water level in winter and spring seasons, pavement design level is low; （2）路面水从路面“三带”、接缝和裂缝中渗入；(2) the surface water from the three zones, joints and cracks in the infiltration; （3）毛细管中的水位上升或相互连通水膜中水的垂直运动；(3) in the capillary water rise or even the water in the water film vertical movement; （4）路肩、绿化带水的渗入。(4) the road shoulder, green water infiltration. 3.2 路面积水原因3.2 the road seeper （1） 非机动车道(1) the non-motor vehicle lanes 施工时，非机动车道横坡控制不好形成反坡；通车后，机动车道沉降量大于非机动车道，导致非机动车道偏高，产生积水。When construction, non-motor vehicle driveways transverse slope control not good form against slope; Opened to traffic, vehicle road subsidence quantity is greater than the non-motor vehicle lanes, lead to non-motor vehicle lanes on the high side, produce water. （2） 接缝渗水(2) joint ooze water （3） 填缝料剥落，导致路面雨水渗入基层。(3) joint sealant spalling, caused the rainwater seeping into the soil. 3.3路面结构层处于水饱和状态，在重载频繁作用下，基层条件恶化3.3 in water saturated state, the pavement structure layer under the effect of overloading is frequent, the basic conditions deteriorate 实践和研究表明，路面过早的破坏在很大程度上是由于水渗入路面结构层引起的。水渗入路面结构层，得不到及时有效排除和处理，就会使得路面结构层长期处于水饱和状态，这是引起路面早期破坏的主要原因。Practice and research show that pavement premature failure is largely due to water seeping into the pavement structure layer. Water seeping into the pavement structure layer, cant get timely and effective eliminate and handling, will be the pavement structure layer in water saturated condition for a long time, this is a major cause of pavement early damage caused. 受综合因素、环境、气候等的影响，使得混凝土路面基层条件恶化，导致面层唧泥、裂缝、断板、错台、拱起等各种病害的发生，进而造成混凝土路面破坏，失去其应有的功能。Influenced by comprehensive factors, environment, climate, etc., makes concrete pavement base conditions deteriorate, leading to pumping mud on the surface, cracks, so, wrong table, arch, etc. The occurrence of various diseases, causing the concrete pavement damage, lost its due function. 路面结构层长期处于水饱和状态，在重载、水泥混凝土板块收缩应力、翘曲应力等重复作用下，使得路基发生唧泥、冻融现象，路基土不均匀膨胀和沉降，细粒材料的冲刷及流失，导致基层脱空，使混凝土板块支承条件恶化。Pavement structure layer in water saturated condition, for a long time in overloading, cement concrete plates, contraction stress, buckling stress under the action of repeated, such as pumping mud, freeze-thaw occur makes roadbed, roadbed uneven expansion and subsidence, soil erosion and loss of fine grained material, lead to grassroots escapes, worsen concrete plate support conditions. 4、防治措施4, prevention and control measures 水毁原因特别复杂，要想有效防治，必须从设计、施工、养护三个环节入手，加强重视。Waterlogging reason extremely complex, to effective prevention and control, must be from the design, construction, maintenance, three links, strengthen the attention. 4.1设计阶段4.1 the design phase 4.1.1横断面4.4.1 cross-sectional 为了保证路面水能够及时排除，横坡以3%为宜，目前横坡设计多为1.5%2%，由于下沉和施工等原因，常出现平坡甚而反坡现象。To ensure the road surface water in a timely manner to eliminate, transverse slope with 3% advisable, cross slope design is 1.5% 2% more, because the reason such as sinks and construction, often appear flat slope even reverse slope phenomenon. 4.1.2排水体系4.1.2 the drainage system 路面下排水不足是引起路面性能不佳和路面早期破坏的主要原因。所以，设计时应考虑一个合理有效、切实可行的排水体系来及时排除路表、路面下各层次的水，以及切断地下水浸入。Insufficient under the pavement drainage is pavement of the main causes of poor performance and pavement early damage. So, the design should be considered a reasonable, effective and feasible road drainage system to timely eliminate table, each level under the water, and cut off the water immersion. 4.1.3接缝4.1.3 seam 必须选用满足功能要求的密封、接缝材料，选择合理的接缝构造尺寸，以切断路面水的浸入。Must be chosen to satisfy functional requirements of sealing, joint materials, choosing reasonable joint structure size, in order to cut off the pavement water immersion. 4.1.4基层4.1.4 grassroots 为了增强对水的抵抗力，提高结构的整体效能，必须设计合适的基层体系，提高基层的水稳性。In order to enhance the resistance to water, increase the efficiency of the structure as a whole, must design the right system at the grass-roots level, enhance the water stability. 4.2施工阶段4.2 construction stage 4.2.1把好“四关”2 the four pass 施工过程中，要严格把好原材料进场关、施工工艺关、现场旁站监理关、各环节验收检测关，必须严格按照公路有关规范、标准要求施工，必须严格按照设计要求施工。Construction process, strictly to give good raw material comes into play, station construction technology, site supervision, acceptance inspection of each link, must be strictly in accordance with the relevant highway construction specifications, standards, requirements, must be in strict accordance with the design requirements for construction. 4.2.2 接缝施工4.2.2 seam construction 必须做好接缝的清洗和表面处理工作。一方面，低质量的密封材料受热时流淌，受冷时脆裂、粘结性低，使接缝丧失防水性。另一方面，施工不当也会使密封材料的性能降低，甚至丧失防水作用。所以接缝施工时要严格按照规范来施工。Must to do a good job of cleaning and surface treatment seam. On the one hand, the low quality of the sealing material flow when heated, form cold brittleness, low bonding, make joint loss of waterproof. Improper construction, on the other hand, also can make the performance of the sealing material is reduced, and even lost the waterproof effect. So the seam construction to construction in strict accordance with the specification. 4.2.3垫层施工Cushion construction holdings 提高垫层的施工质量，在路基施工中，应严格按照操作规程进行，做到分层填筑、分层压实、分层检验。每层质量指标都必须满足设计要求和规范要求，以提高基层的水稳性。Improve cushion layer construction quality, in subgrade construction, should be strictly carried out in accordance with the operating rules, layered filling and compaction, layering, layering. Each layer of quality indicators must meet the design requirements and specification requirements, in order to improve the water stability of grass-roots. 4.2.4面层施工4.2.4 surface 严格控制混凝土板厚和混凝土实际弯拉强度。因为板厚和弯拉强度是影响混凝土路面使用寿命的两个重要因素，板厚的减少和强度的降低都成倍地缩短板块的使用寿命。板块提前损坏使得路表水浸入结构层，进一步形成负面连锁反应。Strictly control the concrete slab thickness and flexural strength of concrete practice. Because the thickness and bending strength are two important factors influencing service life of concrete pavement, thickness reduction and reduce the strength of shortening the service life of the plate are multiplied. Plate damage makes road ahead table structure immersed in water layer, to form a negative chain reaction. 4.3养护阶段4.3 maintenance phase 对于出现的病害，我们采取了灌浆、开设横向排水沟、凿除重浇等相结合的方法进行处治，取得了较好的效果。For emerging diseases, we adopted horizontal grouting, open drain, in addition to the heavy water treatment with the combination of methods, such as, good results have been achieved. （1）凿除重浇。对于破损成3块以上的严重破碎板，可凿除后重新浇筑混凝土板块。对于基层松软的问题，可使用素混凝土和夯实相结合的补强方法，局部设置钢筋网进行补强。(1) the chisel in addition to heavy pouring. For broken into 3 pieces or more severe crushing plate, can be cut again after the pouring concrete plate. For the loose problem at the grassroots level can use the combination of plain concrete and compaction reinforcement method, partial set steel mesh reinforcement. （2）灌浆。对于板底脱空积水的板块和严重裂缝板块进行灌浆处理。(2) the grouting. For pavement seeper plate at the end of the plate and the serious crack grouting processing plate. （3）设置横向排水管。对于排水不畅的地方每隔10m设置一道横向排水。(3) set the horizontal drainage pipe. For poor drainage area every 10 m set a horizontal drainage. （4）灌缝。加强对水泥混凝土路面日常养护灌缝的控制，采用水泥混凝土灌缝机灌缝，严格按照规范进行灌缝的养护，尤其要加强雨季之前的养护工作。(4) the filling and seaming. Strengthen the daily maintenance of concrete pavement crack seal control, USES cement concrete pouring seam JiGuan seam, in strict accordance with the rules in the seam filling and maintenance, especially to strengthen the maintenance before the rainy season. 4.4养护防治要求4.4 maintenance control requirements （1）对路面原有的排水体系，要加强纵、横向疏通，不能满足实际要求的，就应修改完善，以及时有效地排除路面结构层的积水。(1) original of pavement drainage system, to strengthen the longitudinal, transverse dredge, cannot satisfy the actual requirements, it should be amended, and effectively eliminate seeper of pavement structure layer. （2）加强
