熱拌瀝青混合料人工攤鋪及施工要點(diǎn)
來(lái)源：http://www.seatostar.com/ 日期：2022-06-29
將車送來(lái)的瀝青混合料先卸在鐵板上，然后人工鏟平，以扣鏟的方式均勻鋪在路面上。攤鋪時(shí)，不要將鏟子抬得很遠(yuǎn)，以免粗細(xì)骨料分離，同時(shí)用抹刀將一側(cè)抹平。刮的時(shí)候重量要一樣，來(lái)回刮2～3次就夠了，達(dá)到平整。在攤鋪過(guò)程中，應(yīng)隨時(shí)檢查攤鋪厚度、平整度和路拱。如發(fā)現(xiàn)有不妥之處，應(yīng)及時(shí)修復(fù)。
The asphalt mixture delivered by the truck shall be unloaded on the iron plate first, and then manually leveled, and evenly paved on the road surface in the form of buckle shovel. During paving, do not lift the shovel too far to avoid the separation of coarse and fine aggregates. At the same time, use a spatula to level one side. When scraping, the weight should be the same. Scraping back and forth for 2 ~ 3 times is enough to achieve flatness. During the paving process, the paving thickness, flatness and crown shall be checked at any time. If any defect is found, it shall be repaired in time.
瀝青混合料的攤鋪?lái)樞驊?yīng)從進(jìn)料方向由遠(yuǎn)至近逐步進(jìn)行。在可能的情況下，應(yīng)將路面鋪展在路面的整個(gè)寬度上，以避免縱向接縫。如果路面過(guò)寬不能充分鋪裝，可根據(jù)車道寬度分兩次或多次鋪裝，但接縫必須與道路中心線平行，縱向接縫必須緊密搭接以避免凹槽。操作過(guò)程應(yīng)符合施工規(guī)范的要求。
The paving sequence of asphalt mixture shall be gradually carried out from far to near in the feeding direction. Where possible, the pavement shall be spread over the full width of the pavement to avoid longitudinal joints. If the pavement is too wide to be fully paved, it can be paved two or more times according to the lane width, but the joints must be parallel to the road centerline, and the longitudinal joints must be closely overlapped to avoid grooves. The operation process shall comply with the requirements of the construction specification.
人工攤鋪時(shí)，瀝青混凝土混合料的松散攤鋪系數(shù)為1.25-1.50，瀝青碎石為1.20-1.45。
During manual paving, the loose paving coefficient of asphalt concrete mixture is 1.25-1.50, and that of asphalt macadam is 1.20-1.45.
施工準(zhǔn)備
Construction preparation
(1)瀝青面層施工前應(yīng)完成基層的檢驗(yàn)驗(yàn)收。檢查項(xiàng)目包括縱向標(biāo)高、橫向坡度、路面寬度、中心線偏差、平整度，并做好原始記錄。
(1) The inspection and acceptance of the base course shall be completed before the construction of the asphalt surface course. The inspection items include longitudinal elevation, cross slope, pavement width, centerline deviation and flatness, and the original records shall be made.
（2）瀝青混合料攤鋪前，應(yīng)安裝好路牙、平石。如果基層松散，標(biāo)高高低，應(yīng)采取相應(yīng)的修邊處理，如銑邊、襯里等。
(2) Before paving the asphalt mixture, the road teeth and flat stones shall be installed. If the base course is loose and the elevation is high or low, corresponding trimming treatment shall be taken, such as milling, lining, etc.
(3)道路上的雨水進(jìn)水口和檢查井應(yīng)提前升降，以適應(yīng)道路標(biāo)高，并小心壓實(shí)。
(3) Rainwater inlets and manholes on the road shall be raised and lowered in advance to suit the road elevation and carefully compacted.
（4）路面冷茬處或與檢查井、雨水口的連接處，涂油前應(yīng)涂一層刷過(guò)的瀝青粘油。
(4) At the cold stubble of the pavement or at the connection with the inspection well and the rainwater inlet, a layer of brushed asphalt viscous oil shall be applied before applying oil.
（5）根據(jù)項(xiàng)目特點(diǎn)、規(guī)模、設(shè)計(jì)要求等因素，確定機(jī)械設(shè)備配置，選擇攤鋪機(jī)、壓路機(jī)等輔助設(shè)備。
(5) Determine the mechanical equipment configuration according to the project characteristics, scale, design requirements and other factors, and select the paver, roller and other auxiliary equipment.
運(yùn)輸
transport
1、熱拌瀝青混合料應(yīng)采用大噸位卡車運(yùn)輸。施工過(guò)程中，攤鋪機(jī)前應(yīng)有卡車等候，以保證施工的連續(xù)性。一般有5輛以上的卡車在等待。開(kāi)始鋪路。
1. Hot mix asphalt mixture shall be transported by large tonnage truck. During construction, trucks shall be waiting in front of the paver to ensure the continuity of construction. There are usually more than 5 trucks waiting. Start paving the road.
2、瀝青混凝土運(yùn)輸車的車廂應(yīng)保持清潔。裝車前，在車底噴適量柴油水（柴油與水的比例通常為1：3）作為脫模劑（車底不應(yīng)有積液）。自動(dòng)定位，平衡充電以減少混合分離。為保溫、防雨、防污染，宜用薄布覆蓋混合物。3、料車保證良好的性能，防止運(yùn)輸過(guò)程中出現(xiàn)故障，延誤時(shí)間，使瀝青混凝土降溫。物料車進(jìn)場(chǎng)時(shí)，輪胎應(yīng)清潔干凈，確保不污染路面。如果發(fā)現(xiàn)瀝青結(jié)合料沿車廂板滴落，應(yīng)采取措施避免。
2. The carriage of the asphalt concrete transport vehicle shall be kept clean. Before loading, spray an appropriate amount of diesel water (the ratio of diesel to water is usually 1:3) on the bottom of the vehicle as the release agent (there should be no liquid accumulation on the bottom of the vehicle). Automatic positioning and balanced charging to reduce mixing separation. In order to keep warm, prevent rain and pollution, the mixture should be covered with a thin cloth. 3. The hopper car shall ensure good performance, prevent failure during transportation, delay time and cool the asphalt concrete. When the material truck enters the site, the tires shall be clean to ensure that the road surface is not polluted. If asphalt binder is found dripping along the carriage plate, measures shall be taken to avoid it.
4、濟(jì)南瀝青料廠家認(rèn)為在攤鋪施工過(guò)程中，運(yùn)輸車應(yīng)在距行駛中的攤鋪機(jī)10-30cm處停車掛空檔。它不應(yīng)該撞到攤鋪機(jī)。應(yīng)該有專人指揮，直到攤鋪機(jī)接觸到運(yùn)輸車的后部。當(dāng)料斗開(kāi)始卸料時(shí)，料斗由攤鋪機(jī)向前推動(dòng)。
4. Jinan asphalt manufacturer believes that during the paving construction, the transport vehicle should stop at 10-30cm away from the moving paver and shift to neutral. It should not hit the paver. There shall be a specially assigned person to command until the paver contacts the rear of the transport vehicle. When the hopper starts discharging, the hopper is pushed forward by the paver.
