冷再生機將再生混合料拌和均勻并由振動壓路機穩(wěn)壓一遍后,應立即用平地機初步整形。在直線和不設平曲線段,平地機由路肩向路中間刮平;在設的平曲線段,平地機由內(nèi)側(cè)向外側(cè)進行刮平。
After the cold regenerator mixes the recycled mixture evenly and stabilizes it once by the vibratory roller, the grader shall be used immediately for preliminary shaping. In straight and non-flat curve sections, the grader shall level from the shoulder to the middle of the road; In the set flat curve section, the grader shall level from the inside to the outside.
必要時再返回刮一遍,對于局部低洼處,應用鐵鎬將表層5cm以上耙松,并用新拌的混合料進行找平。整形的過程中應及時消除粗細料離析現(xiàn)象。既由人工配合機械把大塊沒有破碎掉的舊路料清除掉。整形時應將高處料直接刮出路外,不應形成薄層貼補現(xiàn)象。
If necessary, go back and scrape again. For local low-lying areas, use an iron pick to loosen the surface layer more than 5cm, and use the freshly mixed mixture for leveling. The segregation of coarse and fine materials shall be eliminated in time during the shaping process. The large pieces of old road materials that have not been broken shall be removed manually and mechanically. During shaping, the high materials should be directly scraped out of the way, and there should be no thin layer of patching.
初平完成后,由振動壓路機高幅/低頻穩(wěn)壓一遍,然后由測量工按照質(zhì)量控制要求分左、中、右三點放樣控制標高和橫坡度(直線段20米1點,彎道10米一點),進行細致找平,達到調(diào)拱度、調(diào)坡度的目的。保證平整度、橫坡度符合設計要求。
After the initial leveling is completed, the vibratory roller shall stabilize the high amplitude/low frequency voltage once, and then the surveyor shall set out and control the elevation and cross slope at the left, middle and right points according to the quality control requirements (one point at 20 meters in the straight section and one point at 10 meters in the curve), and carry out careful leveling to achieve the purpose of camber and slope adjustment. Ensure that the flatness and cross slope meet the design requirements.
冷再生機施工過程中要堅持“寧刮不補”的原則,如果要補料的話,當確定要補5cm以上的混合料,補料的時候,需在新補料中多摻水泥并保證含水量,以確保粘結(jié)性,碾壓的時候能不松散不起皮。做終平工作時,一定要特別小心,確保整個表面刮平,使其縱向順適,路拱和符合設計要求。
During the construction of the cold recycling machine, the principle of "scraping rather than patching" should be adhered to. If it is necessary to make up, when it is determined to make up more than 5cm of mixture, it is necessary to add more cement and ensure the water content in the new material to ensure the cohesiveness, and it is not loose and peeling when rolling. During the final leveling work, special care must be taken to ensure that the entire surface is scraped to make it longitudinal and comfortable, and the road camber meets the design requirements.
冷再生機租賃廠家提醒,不要在低洼處落下刀片,須將局部高出部分刮除并掃出路外,因為這些料與下層料之間是沒有粘結(jié)力的,碾壓的時候容易造成起皮壓不住的現(xiàn)象。終平應仔細進行,對于局部低洼之處,不再進行找補,可留待鋪筑瀝青面層時處理。
The leasing manufacturer of the cold regenerator reminded that the blade should not be dropped in the low-lying place, and the part higher than the blade should be scraped off and swept out, because there is no adhesive force between these materials and the underlying material, and it is easy to cause peeling and crushing when rolling. The final leveling shall be carried out carefully. For local low-lying areas, no need to make up, but can be left for treatment when paving the asphalt surface course.
找平完畢后進行1-2遍碾壓,碾壓前如混合料表面風干,可用灑水車噴灑補水,以防壓不住。初壓時使用高幅/低頻振動模式,以便壓實層面的下部,隨后使用低幅/高頻振動模式壓實再生層的上部。碾壓時應先輕后重,自路邊向路中依次碾壓,碾壓速度應控制在低速度,注意錯輪寬度并且不漏壓。
After leveling, carry out 1-2 times of rolling compaction. If the surface of the mixture is dried before rolling compaction, spray water with a watering cart to prevent it from being crushed. The high amplitude/low frequency vibration mode is used for initial compaction to compact the lower part of the layer, and then the low amplitude/high frequency vibration mode is used to compact the upper part of the regeneration layer. The rolling shall be carried out from light to heavy, from the roadside to the middle of the road in turn, and the rolling speed shall be controlled at a low speed. Pay attention to the width of the staggered wheels and do not miss the rolling.
因為水泥的關系,在施工期間,從加水拌合至碾壓成型灑水養(yǎng)護,不得超過4小時。
Due to the relationship between cement, during the construction period, from mixing with water to rolling and forming, watering and curing shall not exceed 4 hours.
