坑槽修补技术
1、坑槽放线
技术人员察看并根据病害的具体情况,依据“圆坑方补”、 坑槽边缘线与路中心线平行或垂直的原则,确定坑槽挖补范围和开挖边界线.
2、切缝
施工人员按线切割,先长边后短边,交叉角不能过切后欠切,切缝深度不低于开挖深度的80%,并及时清理废料.
3、坑槽开挖
用风镐先中间后周边挖除,逐层开挖到稳定部分,坑槽开挖深度大于8厘米时应按台阶式分层开挖,台阶宽度10—15厘米,坑槽边缘不留毛茬无松动,坑壁垂直成线.
4、坑槽的整理清扫
①用钢刷将坑壁上不稳定颗粒和灰尘清刷干净；②用吹风机或空压机把坑槽的灰尘吹扫干净；③喷灯将坑底及四壁潮湿部位烤干.
5、界面处理
用批刀把界面处理剂均匀涂抹在坑槽四壁上,厚度约2毫米,涂抹时勿污染路面.
6、裂缝处理
①用批刀将界面处理剂均匀、无遗漏地涂抹在裂缝处,把裂缝填平.②测量裂缝长度,截取抗裂贴,揭去隔离膜均匀贴在裂缝上,使抗裂贴与地面牢固结合.
7、喷洒乳化沥青
施工人员用乳化沥青喷洒器向坑底和台阶均匀喷洒适量乳化沥青,洒布量应合适,不存液、不露白.
8、沥青混合料下层摊铺
先测量坑槽深度,采用合理松铺系数,计算出摊铺厚度,当坑槽深度大于8厘米时使用AC-20C沥青混合料分层摊铺,沥青混合料运输必须使用保温运输设备,以保证混合料温度,避免离析.待乳化沥青完全破乳后方可进行摊铺,摊铺时用扣锨法,保证沥青混合料不离析,坑槽边缘用细料填入,摊铺平整后把表面大粒料扫除.
9、下层压实
下层摊铺后,向高频冲击夯底板喷洒隔离剂,对摊铺的沥青混合料进行先周边后中间、平整无痕迹夯实3-4遍,相邻夯实带应重叠夯板的一半宽度.
10、上层摊铺
首先测量坑槽深度,采用合理松铺系数,计算出摊铺厚度,沥青混合料放料温度不低于120度.摊铺时用扣锨法,保证沥青混合料不离析,坑槽边缘用细料填入,摊铺平整后把表面大粒料扫除,要求坑槽四周接缝平整无错台.
11、上面层压实
上层摊铺后,开始用静压方式碾压,最后用震动方式碾压,先周边后中间,纵横结合,直到碾压密实.碾压顺序是先碾压接缝后压中心,相邻碾压带应重叠1/3轮宽以上.碾压时注意坑槽接缝处是否缺料,缺料及时填补,多料及时清理,保证坑槽的碾压密实度,高度、接缝一致.压实后的坑槽应高出原路面2-3毫米,平整度控制在3毫米以内.
12、清理工作现场
坑槽碾压结束后,对施工现场进行清扫,废料及时装车.测量坑槽面层温度降至50度以下方可通车放行.

Answer 1

Pits repair techniques
1,pits-line
According to technical staff and look at the specific circumstances of disease,based on "a round hole to fill," pits the edge line with the road or vertical axis parallel to the principle of determining the scope and excavation pits Wabu boundary line.
2,slotted
Construction of staff by cutting lines,the first after the short side of the border areas,cross-angle can not be cut off after less cutting,slotted depth of not less than 80 percent of the depth of excavation,and promptly clean up waste.
3,excavation pits
By Feng Gao after the first intermediate neighboring Wachu,layer by layer to the stability of the excavation,digging pits at the depth of more than eight centimeters should be stepped layered excavation of 10-15 cm width level,not the edge pits Leaving no loose hair stubble,Kengbi a vertical line.
4,pits the finishing clean-up
① will Kengbi steel brush on the unstable particles and dust-brush cleaner; ② use hair dryer or air compressor to purge and clean the dust pits; ③ torch will damp walls and bottom parts Kaogan.
5,dealing with the interface
Dao interface deal with the appropriation of uniformity in pits coated walls,the thickness of about 2 millimeters,not smear when pollution road.
6,crack treatment
① use interface will be awarded knife handle of uniform,without smearing the omission to cracks,the cracks filled.② measuring the length of cracks,the interception of cracking paste,paste evenly Jiequ isolation in the film cracks,the crack resistance paste with the combination of solid ground.
7,sprayed asphalt emulsion
Construction Service emulsified asphalt sprayers to the bottom level and evenly spraying amount of emulsified asphalt,squandering of cloth should be suitable,not of liquid,Lu Bai.
8,paving asphalt mixture lower
First measurement pits depth,using reasonable-shop factor,calculated paving thickness,when more than eight centimeters deep pits the use of AC-20C asphalt mixture layered paver,asphalt mixture transport must use insulation transportation equipment,To ensure that the mixture of temperature,to avoid isolation.To be completely emulsified asphalt for paving before the breaking,paving Xian deduction method used to ensure that asphalt mixture does not disintegrate,with small edge pits fill material,paving the formation of the surface after wiping out large aggregates.
9,lower compaction
Paving lower after the high-frequency impact to the isolation of ramming floor sprinkler,paving the asphalt mixture to the surrounding after the first intermediate,formed no signs of consolidating 3-4 times,should overlap with neighboring solidify the half-tamping宽度.
10,the upper paver
First of all pits measuring the depth,using reasonable-shop factor,calculated thickness paver,asphalt mixture discharge temperature of not less than 120 degrees.Paving Xian deduction method used to ensure that asphalt mixture does not disintegrate,with small edge pits fill material,paving the formation of the surface after wiping out large aggregates,pits around the joints require no wrong formation Taiwan.
11,compaction of the above
Paving the upper,starting with static manner RCC,with the final vibration mode RCC,after first surrounding the middle,vertical and horizontal integration,until the RCC-compacting.RCC is the first order of rolling joints after pressure center,adjacent RCC should overlap with 1 / 3 width above.RCC attention at the pits at the seams Queliao,Queliao filled in a timely manner,when the clean-up materials and more to ensure that pits the RCC density,height,the same joints.After the compaction of the pits should be higher than the original road 2-3 mm,the formation of control in less than three millimeters.
12,the clean-up site
RCC pits after the end of the construction site for cleaning,waste time loading.Measuring pits surface temperature to 50 degrees below before the opening of release.
