　　（3） Construction method: Before construction, a dedicated person is responsible for setting up road barriers and signs, controlling and directing the movement of vehicles on the half width of the road.

　　1、水泥攤鋪：

　　1. Cement paving:

　　需要根據(jù)結(jié)構(gòu)層的工程量確定水泥的用量，以一米幾袋(技術(shù)員提前算出)為標準，然后在冷再生施工前將路段所需水泥用人工攤鋪好。先向準備施工路段卸水泥，袋裝水泥一般以10米一堆卸好在路邊碼放，雨季施工中需要準備好防雨布，隨時準備遮蓋。鋪前由測量人員放出施工邊線，采用人工撒灰線的方法，圈定結(jié)構(gòu)層施工范圍，以免水泥鋪不到位或浪費。攤鋪的時候需根據(jù)施工當天的天氣情況分段攤鋪水泥，現(xiàn)場施工人員將水泥均勻攤開，并注意使每袋水泥的撒布面積相等。水泥撒布完后，表面應(yīng)沒有空白位置，也沒有水泥過分集中的地點。是在施工前鋪出150米工作面，然后在冷再生施工中以150米為一段流水遞進施工。既水泥攤鋪始終冷再生作業(yè)段150米。以減少水泥的風吹損耗過大和雨季施工天氣突變或機械故障所造成的損失。

　　The amount of cement used needs to be determined based on the engineering quantity of the structural layer, with a standard of several bags per meter (calculated by the technician in advance), and then manually spread the required cement for the road section before cold recycling construction. First, unload the cement to the construction section. Bagged cement is usually unloaded in piles of 10 meters and stacked on the roadside. During rainy season construction, it is necessary to prepare waterproof cloth and be ready to cover it at any time. Before laying, the construction boundary shall be set out by the surveyor, and the construction scope of the structural layer shall be delineated by manually sprinkling the ash line to avoid inadequate or wasteful cement laying. When paving, cement should be spread in sections according to the weather conditions on the day of construction. The on-site construction personnel should evenly spread the cement and pay attention to ensuring that the spreading area of each bag of cement is equal. After the cement is spread, there should be no blank spaces on the surface or areas where cement is excessively concentrated. It is best to lay a 150 meter working surface before construction, and then gradually construct in a flow of 150 meters during cold recycling construction. The cement paving always leads the cold recycling operation section by 150 meters. To reduce the excessive wind loss of cement and the losses caused by sudden weather changes or mechanical failures during rainy season construction.

　　水泥攤鋪環(huán)節(jié)有條件的是選用水泥稀漿車或粉料撒布車進行，節(jié)省人工、效率高，均勻污染少。

　　If conditions permit, it is best to use cement slurry trucks or powder spreading trucks for cement paving, which saves labor, has high efficiency, and causes less uniform pollution.

　　2、冷再生機作業(yè)：

　　2. Cold regeneration machine operation:

　　冷再生機一次破碎拌合寬度為2.4米，工作時需有一輛水罐車緊跟作業(yè)保證拌合用水，拌合過程中按照試驗單所規(guī)定的高于含水量1-2%控制用水（前提是需要知道再生機能打開幾個水噴嘴來換算含水量），另有一輛水罐車需滿水隨時處于待命狀態(tài)，一旦跟再生機作業(yè)的水罐沒水了，需即刻補上。以保證冷再生機的持續(xù)作業(yè)能力。冷再生機行進速度應(yīng)根據(jù)路面損壞狀況和再生深度進行調(diào)整，一般為6m/min～12m/min，使得銑刨后料的級配波動范圍不大。網(wǎng)裂嚴重地段應(yīng)降低再生機組行進速度，提高銑刨轉(zhuǎn)子轉(zhuǎn)速。如舊路面層結(jié)構(gòu)層厚度大于8cm，冷再生機行走困難，則需先由冷再生機對舊路面層進行銑刨后，在破碎料上再鋪水泥，進行冷再生拌合施工。冷再生工作過程中需要人員跟隨隨時檢查拌合深度和濕度，一般以20米一點為準。如有不合格要及時跟司機反映以便解決。每冷再生施工作業(yè)時，振動壓路機必須跟在冷再生機后側(cè)20m處，對拌合完的混合料及時采用高幅低頻振動碾壓一遍，速度等同于冷再生機的行車速度。目的趁含水量時把水封在混合料里。

　　The crushing and mixing width of the cold regeneration machine is 2.4 meters. During operation, a water tank truck is required to closely follow the operation to ensure the mixing water. During the mixing process, the water consumption should be controlled according to the test sheet, which is 1-2% higher than the optimal water content (provided that it is known how many water nozzles the regeneration machine can open to convert the water content). Another water tank truck needs to be fully filled and on standby at all times. Once the water tank working with the regeneration machine runs out of water, it needs to be replenished immediately. To ensure the continuous operational capability of cold regeneration. The traveling speed of the cold recycling machine should be adjusted according to the condition of road damage and the depth of recycling, generally ranging from 6m/min to 12m/min, so that the gradation fluctuation range of the milled material is not large. In areas with severe mesh cracking, the speed of the regeneration unit should be reduced and the milling rotor speed should be increased. If the thickness of the structural layer of the old pavement layer is greater than 8cm and it is difficult for the cold recycling machine to move, the cold recycling machine needs to first mill the old pavement layer, and then lay cement on the crushed material for cold recycling mixing construction. During the cold regeneration process, personnel are required to follow and check the mixing depth and humidity at any time, usually at a rate of 20 meters. If there are any non conformities, they should be reported to the driver in a timely manner for resolution. During each cold recycling construction operation, the vibrating roller must be placed 20 meters behind the cold recycling machine, and the mixed material must be promptly compacted with high amplitude and low frequency vibration once, at a speed equivalent to the driving speed of the cold recycling machine. The purpose is to seal the water in the mixture at the optimal moisture content.

　　再生施工時應(yīng)考慮兩種接縫：與道路中心線平行的縱向接縫和與道路中心線垂直的橫向接縫。

　　Two types of joints should be considered during regeneration construction: longitudinal joints parallel to the centerline of the road and transverse joints perpendicular to the centerline of the road.

　　縱向接縫：再生機的工作寬度一般小于道路或行車道的寬度，因此，全幅路的冷再生需多次作業(yè)，從而導致和相鄰作業(yè)面間的縱向接縫。需要沿整條縱縫有一定的重疊量以保證相鄰作業(yè)面間縱縫的連續(xù)性。相鄰作業(yè)面間的重疊量不小于10cm。路面越厚，重疊量越大；材料粒徑越粗，重疊量越大；相鄰兩次作業(yè)間隔12h以上時，重疊量應(yīng)增加。在縱向接縫上，根據(jù)已建再生層的完成時間，改變水的噴入量?？v向接縫的位置應(yīng)盡量避開緩慢行駛的重型車輛的輪跡。施工時應(yīng)通過在現(xiàn)有路面上醒目標志或測量基準線的方法建立導向提示，幫助駕駛員正確操縱再生機，避免相鄰作業(yè)面間存在未拌合的的夾生帶。

　　Longitudinal seam: The working width of the regeneration machine is generally smaller than the width of the road or roadway, so the cold regeneration of the entire road requires multiple operations, resulting in longitudinal seams between adjacent working surfaces. There needs to be a certain amount of overlap along the entire longitudinal seam to ensure the continuity of the longitudinal seam between adjacent work surfaces. The overlap between adjacent work surfaces shall not be less than 10cm. The thicker the road surface, the greater the overlap; The coarser the particle size of the material, the greater the overlap; When the interval between two adjacent assignments is more than 12 hours, the overlap should be increased. On the longitudinal seam, adjust the amount of water sprayed according to the completion time of the existing regeneration layer. The position of longitudinal joints should avoid the wheel tracks of slow-moving heavy vehicles as much as possible. During construction, guidance prompts should be established by prominently marking or measuring reference lines on the existing road surface to assist drivers in correctly operating the regeneration machine and avoid the presence of unmixed intermediate zones between adjacent work surfaces.

　　橫向接縫：因每次施工開始或終止而形成的橫向接縫是不連續(xù)的。每次停機，即使是僅需幾分鐘用于更換罐車、刀頭，也將形成一個嚴重影響再生材料均勻性的橫縫。因此施工中盡量減少停機現(xiàn)象，在不可避免的情況下，應(yīng)對所形成的橫縫進行重疊認真處理。處理橫向接縫時需要注意含水量，一般起刀落刀時含水量按正常減半。再生施工開始時，所有開始步驟必須嚴格依次進行，特別是水管的排氣程序。所有氣體必須在水到達噴灑桿前排除，如果排氣不當，有可能在再生施工開始的初幾米內(nèi)，混合料內(nèi)無水，從而導致路面內(nèi)出現(xiàn)非穩(wěn)定路段。在臨時停機后重新開始時，整個再生機組應(yīng)該后退少一個轉(zhuǎn)子直徑的距離既1.5-2米到達再生過的材料上。這將保證開始施工后所有材料均得到處理。停機超過水泥初凝時間，再生機再次施工時，必須將整個再生機后退再生過的路段1.5m的距離，并重新撒布水泥。橫縫問題只有當施工停止時才會出現(xiàn)。因此，再生機組只能在罐車用空后或類似情況下才能停機。施工中盡量減少停機現(xiàn)象，在每打完一段整幅路后再更換刀頭，以不影響后續(xù)工序的展開。

　　Horizontal joint: The horizontal joint formed at the beginning or end of each construction is discontinuous. Every shutdown, even if it only takes a few minutes to replace the tanker truck and blade, will create a serious transverse seam that affects the uniformity of the recycled material. Therefore, during construction, efforts should be made to minimize downtime, and in unavoidable situations, overlapping horizontal joints should be carefully treated. When dealing with horizontal joints, attention should be paid to the moisture content. Generally, the moisture content is halved when lifting and dropping the knife. At the beginning of the regeneration construction, all starting steps must be strictly carried out in sequence, especially the exhaust program of the water pipes. All gases must be expelled before the water reaches the spray bar. If the exhaust is not proper, there may be no water in the mixture during the first few meters of regeneration construction, resulting in unstable road sections on the road surface. When restarting after a temporary shutdown, the entire regeneration unit should retreat at least one rotor diameter distance of 1.5-2 meters to reach the regenerated material. This will ensure that all materials are processed after the start of construction. When the shutdown exceeds the initial setting time of the cement and the regeneration machine is restarted, the entire regeneration machine must be moved back to a distance of 1.5 meters from the regenerated section and the cement must be re spread. The problem of transverse joints only occurs when construction is stopped. Therefore, it is best to stop the regeneration unit only when the tanker is empty or in similar situations. Try to minimize downtime during construction, and it is best to replace the blade after completing each section of the entire road to avoid affecting the subsequent process.

　　再生拌和均勻后應(yīng)色澤一致，沒有灰條、灰團和花面，即無明顯粗細料離析現(xiàn)象，且水分合適、均勻。每天冷再生施工結(jié)束時清洗刀頭一定要遠離當日施工段的路面進行，以防止洗刀水流入剛打完的路面結(jié)構(gòu)中造成人為軟基。

　　After regeneration and mixing evenly, the color should be consistent, without gray strips, gray clusters, or flower surfaces, that is, there should be no obvious separation of coarse and fine materials, and the moisture content should be appropriate and uniform. At the end of each day's cold recycling construction, the cleaning blade must be kept away from the road surface of the construction section to prevent the washing blade from flowing into the newly completed road structure and causing artificial soft foundation.

　　3、整形及碾壓：

　　3. Plastic surgery and compaction:

　　再生混合料拌和均勻并由振動壓路機穩(wěn)壓1遍后，應(yīng)立即用平地機初步整形。在直線和不設(shè)超高的平曲線段，平地機由路肩向路中心進行刮平；在設(shè)超高的平曲線段，平地機由內(nèi)側(cè)向外側(cè)進行刮平。必要時再返回刮一遍，對于局部低洼處，應(yīng)用鐵鎬將其表層5cm以上耙松，并用新拌的混合料進行找平。整形過程中應(yīng)及時粗細料離析現(xiàn)象。既由人工配合機械把大塊沒有破碎掉的舊路料掉。整形時應(yīng)將高處料直接刮出路外，不應(yīng)形成薄層貼補現(xiàn)象。

　　After the recycled mixture is evenly mixed and stabilized by a vibratory roller once, it should be immediately preliminarily shaped using a grader. On straight lines and flat curved sections without superelevation, the grader flattens from the shoulder towards the center of the road; When setting a super-high flat curve section, the grader flattens it from the inside to the outside. If necessary, return and scrape again. For locally low-lying areas, use an iron pick to loosen the surface layer by more than 5cm and level it with freshly mixed material. During the plastic surgery process, the phenomenon of coarse and fine material segregation should be eliminated in a timely manner. Both manually and mechanically remove large pieces of old road material that have not been broken. During plastic surgery, the high material should be directly scraped out of the road without forming a thin layer of patching.

　　平地機初平完成后,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），指導平地機進行細致找平，達到調(diào)拱度、調(diào)坡度的目的。保證平整度、橫坡度符合設(shè)計要求。施工中要堅持“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。在用平地機做的終平工作時，一定要特別小心，確保對整個表面進行刮平，使其縱向順適，路拱和超高符合設(shè)計要求。不要在低洼處落下刀片，必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現(xiàn)象。終平應(yīng)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。

　　After the initial leveling of the grader is completed, the vibrating roller stabilizes the high amplitude/low frequency once, and then the surveyor sets out and controls the elevation and cross slope (1 point for straight sections at 20 meters and 1 point for curved sections at 10 meters) at three points on the left, middle, and right according to quality control requirements, guiding the grader to perform detailed leveling to achieve the purpose of adjusting the arch and slope. Ensure that the flatness and cross slope meet the design requirements. During construction, the principle of "better scraping than patching" should be adhered to. If material needs to be added, when it is determined that more than 5cm of the mixture needs to be added, more cement should be added to the new material and the moisture content should be ensured to ensure adhesion and prevent loosening or peeling during compaction. When using a grader for the final leveling work, special care must be taken to ensure that the entire surface is scraped flat, making it longitudinally smooth, and the road arch and superelevation meet the design requirements. Do not drop the blade in low-lying areas. The locally raised parts must be scraped off and swept out, as there is no bonding force between these materials and the lower layer, which can easily cause peeling and inability to press during compaction. The final leveling should be carried out carefully. For locally low-lying areas, no further filling is required, and they can be left to be treated when laying the asphalt surface layer.

　　找平完畢后由振動壓路機進行1-2遍碾壓，碾壓前如混合料表面風干，必要時由灑水車噴灑補水，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。碾壓原則先輕后重，自路邊向路中依次碾壓，碾壓速度應(yīng)控制在速度，注意錯輪寬度并且不漏壓。另外，使用振動壓路機的時候，應(yīng)注意以下幾點：路面有油氣管線橫過路管的兩側(cè)1米范圍內(nèi)，不可采用振動模式壓實。使用高幅/低頻振動模式壓實往往會擾動層面頂部的材料，尤其是表面。不過在使用低幅/高頻振動模式壓實之前用平地機找平可以修正過來。若達到材料的密度后仍然繼續(xù)碾壓，則會破壞材料，降低材料的密度。根據(jù)混合料的厚度和外在表現(xiàn)形式防止過壓。

　　After leveling, the vibratory roller shall be used for 1-2 passes of rolling. If the surface of the mixture is air dried before rolling, it may be necessary to use a sprinkler truck to spray water if necessary to prevent it from being crushed. Use high amplitude/low frequency vibration mode during initial compaction to compact the lower part of the layer, and then use low amplitude/high frequency vibration mode to compact the upper part of the regeneration layer. The principle of rolling should be light first and then heavy, rolling from the roadside to the middle of the road in sequence. The rolling speed should be controlled at the lowest speed, and attention should be paid to the width of the wrong wheel and not missed. In addition, when using a vibratory roller, the following points should be noted: within a 1-meter range of oil and gas pipelines crossing the road surface, vibration mode compaction should not be used. The use of high amplitude/low frequency vibration modes for compaction often disturbs the material at the top of the layer, especially the surface. However, leveling with a grader before using low amplitude/high-frequency vibration mode for compaction can be corrected. If rolling continues even after reaching the maximum density of the material, it will damage the material and reduce its density. Prevent overpressure based on the thickness and external manifestation of the mixture.

　　由18-21T光輪壓路機進行終壓。壓路機以1檔低速行駛，2臺壓路機以錯1/2大輪能互換過道路施工中線為準，后輪壓完路面全寬時即為一遍。碾壓2-3遍，碾壓原則由兩側(cè)路中，以保持住路拱。由振動壓路機快速行走一遍除去明顯輪跡，碾壓結(jié)束。嚴禁壓路機在已完成的或正在碾壓的路段上調(diào)頭或急剎車，應(yīng)保證再生層表面不受破壞。碾壓過程中，再生層的表面應(yīng)始終保持濕潤，如水分蒸發(fā)過快，應(yīng)及時補撒少量的水，但嚴禁大量灑水碾壓。碾壓過程中，如有“彈簧”、松散、起皮等現(xiàn)象，應(yīng)及時翻開重新拌和（加適量的水泥）或用其他方法處理，使其達到質(zhì)量要求。

　　Finally, the 18-21T light wheel roller is used for final compaction. The road roller travels at a low speed in first gear, and two rollers can cross the construction centerline of the road with half of their large wheels interchangeable. When the rear wheels have pressed the full width of the road surface, it is considered as one pass. Roll 2-3 times, from both sides to the center of the road, to maintain the road arch. Finally, the vibrating roller quickly travels once to remove obvious wheel marks, and the rolling is completed. It is strictly prohibited for the roller to turn around or brake abruptly on the completed or rolling road section, and the surface of the regeneration layer should be ensured not to be damaged. During the rolling process, the surface of the regeneration layer should always be kept moist. If the water evaporates too quickly, a small amount of water should be sprinkled in a timely manner, but it is strictly prohibited to sprinkle a large amount of water for rolling. During the rolling process, if there are "springs", looseness, peeling and other phenomena, they should be promptly opened and re mixed (with an appropriate amount of cement) or treated with other methods to meet the quality requirements.

　　因為水泥的關(guān)系，在施工期間，從加水拌合碾壓成型灑水養(yǎng)生，不應(yīng)超過4個小時。

　　Due to the nature of cement, during the construction period, it should not exceed 4 hours from mixing with water to rolling and shaping with water for curing.

　　4、灑水養(yǎng)生

　　4. Watering for health preservation

　　完成碾壓后，水罐車進行灑水養(yǎng)生，灑水時注意邊角要灑到，不能遺漏，灑水養(yǎng)生時使噴出的水成霧狀，避免將水直接噴射，防止將成型表面沖成離析或坑洼。每天灑水的次數(shù)應(yīng)視氣候而定。整個養(yǎng)生期間應(yīng)始終保持穩(wěn)定土層表面潮濕，因含水泥但不封閉交通，水量不易過大，限制重車通行，其他車輛的車速不應(yīng)超過30km/h，以防施工完成路段被過往車輛壓出明顯車轍，養(yǎng)生期不少于7天。

　　After the compaction is completed, the water tanker truck is sprayed with water for curing. When spraying water, attention should be paid to the edges and corners, and no omissions should be made. When spraying water for curing, the sprayed water should be misty to avoid direct spraying and prevent the formed surface from being washed into segregation or potholes. The frequency of watering per day should depend on the climate. Throughout the entire health preservation period, the surface of the stable soil layer should be kept moist. Due to the presence of cement but not closed traffic, the amount of water should not be too large, and heavy vehicles should be restricted from passing through. The speed of other vehicles should not exceed 30km/h to prevent obvious ruts from passing vehicles on the completed road section. The health preservation period should not be less than 7 days.

　　二、注意事項

　　2、 Precautions

　　（一）控制要點

　?。?） Control points

　　1、混合料含水量現(xiàn)場監(jiān)測辦法，一手抓起一把混合料，用力握實，然后松手讓其自由落向地面，正常會立即摔散花，里面沒有小團料。反復試驗，介于落地松散和抱團之間的臨界含水量即含水量，一般比試驗單上的含水量數(shù)值多1%-2%。

　　1. The optimal on-site monitoring method for the moisture content of the mixture is to grab a handful of the mixture with one hand, firmly grasp it, and then release it to let it fall freely to the ground. Normally, it will immediately scatter without any small lumps inside. Repeated experiments have shown that the critical moisture content between loose ground and clumping, which is the optimal moisture content, is generally 1% -2% higher than the optimal moisture content value on the test sheet.

　　2、作業(yè)施工水罐車停車時一定要離開已施工或待施工水泥已攤鋪路面，以防止漏水引起的局部水大。

　　2. When parking the construction water tank truck, it is necessary to leave the already constructed or to be constructed cement paved road surface to prevent local water accumulation caused by water leakage.

　　3、施工車輛停放時一定要錯開第二天的段道預工作面，以防止耽誤第二天的人工水泥攤鋪，施工車輛不要停放在已完成施工的路面上。防治破壞新建結(jié)構(gòu)和影響后期灑水養(yǎng)生。

　　3. When parking construction vehicles, they must be staggered from the first section of the pre work surface the next day to prevent delaying the manual cement paving the next day. It is best not to park construction vehicles on the road surface that has already been constructed. Prevent and control the damage to newly constructed structures and the impact on later watering and health preservation.

　　4、避免犯“過壓”的錯誤，即過度壓實。若達到材料的密實度后仍然繼續(xù)碾壓，則會破壞材料，反而降低其密實度。

　　4. Avoid making the mistake of "over compaction", that is, excessive compaction. If rolling continues even after reaching the maximum density of the material, it will damage the material and instead reduce its density.

　　5、冷再生機的施工作業(yè)應(yīng)該在每天下午15:00—16:00之間結(jié)束，以便后續(xù)施工能在天黑前結(jié)束。

　　5. The construction operation of the cold recycling machine should be completed between 3:00 pm and 4:00 pm every day, so that subsequent construction can be completed before dark.

　　6、每天冷再生機結(jié)束施工進行洗刀停車后，應(yīng)通知操作手仔細檢查車況并更換刀頭，以免耽誤第二天的施工進度。

　　6. After the construction of the cold recycling machine is completed and the knife washing is stopped every day, the operator should be notified to carefully inspect the condition of the vehicle and replace the knife head to avoid delaying the construction progress of the next day.

　　三、常見問題的處理方法

　　3、 Common problem handling methods

　　1、如果混合料局部水大的話，為防止翻漿壓不住。需將水大的混合料挖出換成含水量適合的混合料（如是碾壓完成的施工段需多摻水泥）回填后，進行人工找平后壓路機碾壓。

　　1. If there is a large amount of water in the local area of the mixture, in order to prevent the slurry from boiling and not being able to be pressed down. The mixture with high water content needs to be excavated and replaced with a mixture with suitable water content (if the construction section has been compacted, more cement needs to be added) for backfilling. After manual leveling, the road roller should be used for compaction.

　　2、如有施工完路段，發(fā)現(xiàn)漏條或跳打現(xiàn)象，由人工在冷再生漏打的地域按比例鋪上水泥，再生機重新倒車作業(yè)重打，如是漏打的地方很小，則小應(yīng)鋪滿冷再生轉(zhuǎn)子一樣大的地方，由再生機扣刀打一下即抬起，原則就是避免多打，破壞已完成的結(jié)構(gòu)。

　　2. If there is a section of road that is missing or skipped during construction, cement should be manually laid in proportion in the area where the cold recycling was missed. The recycling machine should then reverse and redo the work. If the missed area is very small, it should be covered with a minimum of the same size as the cold recycling rotor. The recycling machine should then lift it up with a knife to avoid over hitting and damaging the completed structure.

　　3、如果雨季施工水泥已鋪到路上，趕上下雨，視雨水大小情況，適當減少或停止冷再生機作業(yè)的供水，用振動壓路機迅速振動碾壓一遍后，如混合料沾輪情況嚴重，平地機迅速找平后停止光輪壓路機碾壓，用振動壓路機振動碾壓2遍后即可。

　　3. If the cement has already been laid on the road during the rainy season and it rains, depending on the size of the rainwater, the water supply for the cold recycling machine operation should be reduced or stopped appropriately. After using a vibrating roller to quickly vibrate and roll once, if the mixture is seriously stuck to the wheels, the grader should quickly level it and stop the smooth wheel roller from rolling. Use a vibrating roller to vibrate and roll twice before rolling.
