复压摊铺混合料施工办法.doc

复压摊铺混合料施工办法在混合料完成摊铺和刮平后应立即对路面进行检查，对不规则之处应及时用人工进行调整，随后进行充分、均匀的压实。压实分为初压、复压和终压，压路机应以均匀速度行驶。压实设备必须配有钢轮压路机、大吨位轮胎压路机及大吨位振动压路机，能按合理的压实工艺进行组合压实。并应备有经监理工程师所认可的小型振动压路机或手扶振动夯具，以用于在狭窄地点压实或修补工程。Done in mixture paving and leveling shall be carried out on the road immediately after inspection, should be timely to the irregular differences with artificial adjustment, then adequately, uniform compaction. Compaction is divided into the early pressure, pressure and pressure, roller should be moving at uniform speed. Compaction equipment must be equipped with steel roller, large-tonnage tyre roller, and a large tonnage vibratory roller, can according to the reasonable compaction compaction process are combined. And by the supervision engineer should be accepted small vibratory roller or walking vibration rammer, for the narrow site compaction or repair project. 初压采用轻型钢筒式压路机或关闭振动的振动压路机碾压，初压后检查平整度和路拱，必要时应予以修整。复压紧接在初压后进行，复压宜采用重型的轮胎压路机，也可采用振动压路机。终压紧接在复压后进行，终压应采用双轮钢筒式压路机或关闭振动的振动压路机碾压。碾压工作应按试验路确定的试验结果办理。Early USES light steel cylinder pressure roller on or off the vibration of the vibration road roller, the initial pressure after check the flatness and hump, when necessary, should be finish. After the pressure immediately after the initial pressure, after pressure appropriate USES heavy duty tire roller, vibratory roller may be adopted. Finishing pressure immediately after the double pressure, pressure should use double steel cylinder roller or off the vibration of the vibration road roller. RCC work shall be handled according to determine the test results of the experiment. 在碾压期间，压路机不得中途停留、转向或制动。当压路机来回交替碾压时，前后两次停留地点应相距10m以上，并应驶出压实起始线3m以外。压路机不得停留在温度高于50的已经压实过的混合料上。同时应采取有效措施，防止油料、润滑油、汽油等其他有机杂质在压路机操作或停放期间掉落在路面上。During the roller compaction roller may stopover, steering or braking. When alternating back and forth roller compaction, two stay place should be above 10 m apart, and should be out of the compaction starting line outside of 3 m. Roller shall not stay at temperatures above 50 has been compacted mixture. Effective measures should be taken at the same time, prevent oil, lubricating oil, gasoline and other organic impurities in roller or parking operation during the fall on the road. 在压实时，如接缝处（包括纵缝、横缝或其他原因而形成的施工缝）的混合料温度已经不能满足压实温度要求，应采用加热器提高混合料的温度达到要求的压实温度，再压实到无缝迹为止。否则，必须垂直切割混合料并重新铺筑，立即共同碾压到无缝迹为止。在压路机压不到的地方，应采用热的手夯或机夯把混合料充分压实。已经完成碾压的路面，不得修补表皮。环境与交通量因素的负效应常常使裂缝迅速扩散，严重影响沥青加铺层的使用寿命。如何控制反射裂缝产生的时间和扩散速度是必须解决的关键问题。In real time, such as the joint (including longitudinal seam, joints or other reasons and construction joint) formed by the mixture temperature cannot meet the requirements of compaction temperature, heater should be adopted to improve the temperature of the mixture meet the requirements of compaction temperature, the pressure actually realized seamless track again. Otherwise, must be vertical cutting mixture paving, and common rolling at the seamless track immediately. Pet-name ruby in the reach of the roller pressure, should adopt the hot hand tamper or machine tamper mixture full compaction. Have finished rolling road, can not repair skin. The negative effects of environmental and traffic factors often make crack spread, seriously affect the service life of the asphalt layer. How to control the time of reflection cracks and diffusion velocity is the key problem that must solve. 旧水泥混凝土路面加铺层，由于接缝、裂缝的存在，其作为基层后整体的强度降低，而且在外力荷载作用下，沥青混凝土加铺层处于复杂的三维应力作用的状态下。车辆通过不连续的板体时，沥青混凝土加铺层由于接缝、裂缝的两侧相邻板块产生了纵向的位移差而出现了较大的剪应力，它是产生反射裂缝的主要原因。Old cement concrete pavement overlay layer, as a result of the existence of joint and crack, the lower the strength of the as grassroots after the whole, and under outside force load, asphalt concrete paving layer under complex three dimensional stress state. Vehicles, when passing a discontinuous board of asphalt concrete paving layer due to the seams, cracks produced longitudinal displacement difference on both sides of the adjacent plate and a larger shear stress, it is the leading cause of reflection cracks. 用人工清扫或用水清洗已处理好的旧水泥混凝土路面，保证路面无污染，杂物清除干净，同时一定要保持路面干燥。铺筑防水材料：果树苗沿原有水泥混凝土面板纵、横向接缝处铺筑app改性沥青防水卷材，防水卷材宽度1m。防水卷材施工采用热熔铺贴法，在纵、横向接缝处涂刷sbs改性沥青防水卷材冷底油，要求涂刷均匀，一次到位。然后将防水卷材按位摆正，用天车喷灯加热卷材卷材和混凝土面板，待卷材表面熔化后开始铺贴，要求压实压平，防止翘边。铺洒沥青粘层油：在准备好的干燥旧路面上，喷洒粘层油，粘层油采用改性乳化沥青。铺筑0.8cmes-3型稀浆封层。铺筑玻纤格栅：在水泥混凝土面板纵、横向接缝处铺筑玻纤格栅，玻纤格栅应用铁钉及铁皮将玻纤格栅固定在沥青混凝土应力吸收层上，防止沥青摊铺将玻纤格栅卷起。注意事项：玻纤格栅铺筑过程中，应封闭交通，除施工车辆外，其它车辆只有在紧急情况下才允许在铺好的玻纤格栅上缓慢通过。施工过程中应避免车辆在玻纤格栅上转弯或急刹车。1) treated with artificial cleaning or washing with water has good old cement concrete pavement, to ensure road clean, clear out clutter, and must keep the road dry. Paving waterproof material (2) : the original cement concrete slab longitudinal and transverse seams paving app modified asphalt waterproofing materials, waterproofing materials width 1 m. Waterproofing construction using hot melt shop sticks method, longitudinal and transverse seams in besmear to brush the SBS modified asphalt waterproof coiled material cold bottom oil, coating uniform requirements, once in place. Then waterproof coiled material according to straighten, with burner heating coil coil and concrete face plate, coil surface melt after the shop is stuck, require compaction planish, prevent become warped edge. (3) spray adhesive layer asphalt oil: in the prepared dry old pavement, oil spray glue layer, adhesive layer oil by modified emulsified asphalt. (4) paved 0.8 cmes - 3 type of slurry seal.
