12、員：雷雙馬2、機械組合2000型瀝青拌和設(shè)備套、灑水車2臺、20T自卸汽車8輛、50裝載機3臺、WPD750型攤鋪機、26T膠輪壓路機12T雙光輪壓路機各1臺三、施工工藝1、施工準備（1）在試驗段開工前，由監(jiān)理工程師認可的試驗室根據(jù)規(guī)范和設(shè)計要求，對擬采用的各種集料、填料和瀝青進行原材料試驗并進行混合料組成設(shè)計，根據(jù)試驗室配合比在拌合站試拌，以確?；旌狭霞壟浣M成、結(jié)合料含量、拌合溫度、馬歇爾穩(wěn)定度、流值、密實度、空隙率等技術(shù)指標符合規(guī)范要求。同時對用于本工程的全部的試驗儀器進行調(diào)試，配備足夠的熟練的試驗人員后，以上試驗數(shù)據(jù)及集料類型、集料來源、瀝青來源、種類等一并呈報監(jiān)理工程師審批。根據(jù)試驗段

13、總結(jié)的數(shù)據(jù)確定混合料的穩(wěn)定性及拌和、運輸、攤鋪、碾壓和各機械設(shè)備的配合和組合，并選定各層的攤鋪速度、松鋪厚度、攤鋪機與壓路機組合及碾壓方式和遍數(shù)等。（2）據(jù)計劃安排，準備足夠數(shù)量施工用的粗集料、細集料、填料、瀝青，各種材料進場前對其質(zhì)量進行嚴格檢查，質(zhì)量不合格不得使用。面層施工前對下承層按質(zhì)量標準進行驗收，質(zhì)量合格后方可進行該層施工。（3）對工程用的各種施工機具進行檢查維修，確保路面工程施工連續(xù)均衡順利進行。（4）瀝青混合料配比試驗原材料準備：準備好符合要求的道路石油瀝青、碎石料、砂及礦粉，計算出各種材料的用量比例，使混合料級配組成符合要求，初步選定各種材料的用量比例。馬歇爾試驗：以推薦的瀝青

14、含量的中值為中值，按0.5%的瀝青含量間隔，用已初步選定的各種礦料比例作馬歇爾試件，測定試件的密度，計算空隙率、瀝青飽和度、礦料間隙率等物理指標；進行馬歇爾試驗，測定穩(wěn)定度、流值等物理力學(xué)指標。繪制密度、穩(wěn)定度、流值、空隙率、飽和度同瀝青含量的關(guān)系圖，綜合選定滿足各項指標要求的最佳瀝青含量。 水穩(wěn)定性檢驗：按選定的最佳瀝青含量制作馬歇爾試件，進行浸水馬歇爾試驗，檢驗是否符合規(guī)范要求，如水穩(wěn)定性檢驗不合格，則需重新調(diào)整瀝青含量及配比，必要時增加抗剝離劑措施等重新進行試驗，直到符合要求為止。最后確定各種礦料(及抗剝離劑)的比例及瀝青含量。2、瀝青碎石下面層施工程序：測量放樣掛線瀝青混合料拌和運輸攤

15、鋪碾壓養(yǎng)生3、施工方案：瀝青混合料采用2000型拌和站拌制。4.5m瀝青混凝土攤鋪機攤鋪。4、施工工藝：(1)透層瀝青施工材料要求： 瀝青透油層：透層瀝青采用慢裂灑布型乳化瀝青PC-2。石屑：石屑采用石灰?guī)r石屑，粒徑在23mm之間，石屑干凈無泥土等雜物。施工：施工前對基層進行全面檢查，先施工放樣，放出灑布邊線，用鼓風機認真清掃，使基層表面無浮土，干燥、潔凈。灑布瀝青時，對結(jié)構(gòu)物予以覆蓋保護，以免造成污染。按試驗段確定用量定好車速，一次噴灑成功。對未灑布到的地方用人工補灑，對局部未滲入基層的多余瀝青及時清除。瀝青灑布24小時后，撒布一層石屑，用量約23m31000m2，勻鋪一層，然后用6-8t鋼

16、筒式壓路機穩(wěn)壓兩遍。在基層未驗收合格或氣溫低于10或降雨時，不進行施工，施工后，及時封閉交通。透層瀝青在瀝青碎石下面層施工前至3天灑布，讓透層瀝青充分滲入基層。(2)熱拌瀝青混合料面層施工材料準備：各種材料的料場及瀝青生產(chǎn)廠經(jīng)監(jiān)理工程師認可后，開始進料。拌和站嚴格控制各種用料的質(zhì)量并備足夠數(shù)量的材料，以滿足施工進度要求。 瀝青混合料的拌和： 根據(jù)試驗選定并經(jīng)監(jiān)理工程師批準的原材料瀝青配合比，進行瀝青混合料拌和施工，并嚴格地按照操作工藝操作，以滿足本合同段的瀝青混合料質(zhì)量要求。在拌和過程中，按要求進行各種檢測工作，實驗室至少每天上、下午各做一次瀝青砼的馬歇爾試驗，以監(jiān)測穩(wěn)定度、流值、空隙率、密度

17、、級配及油石比的指標波動是否滿足規(guī)范要求，以便及時予以調(diào)整，同時檢測每批進場瀝青針入度、穩(wěn)定度、軟化點及抽驗進場骨料的規(guī)格和材質(zhì)等。瀝青混合料的拌合設(shè)備擬采用60連續(xù)型和500間歇式拌制設(shè)備，該設(shè)備生產(chǎn)過程全部自動控制，其步驟如下：向總控制室電腦輸入瀝青混合料的級配資料，然后由輸送帶將各集料裝進相應(yīng)的冷料倉，經(jīng)初步計量后進入加熱滾筒加熱，自動控制加熱溫度，再篩分各熱料倉，由控制室發(fā)出指令自動計量后進入拌合缸，同時自動加入經(jīng)計量的瀝青，充分拌合后進入儲料倉，等待汽車裝運。對于瀝青采用導(dǎo)熱油加熱，加熱油溫度控制在150170范圍內(nèi)，礦料加熱溫度比瀝青加熱溫度高1020，混合料出廠溫度控制在1401

18、65，當瀝青混合料出廠溫度過高(超出高限30時)，已影響瀝青與集料的粘結(jié)力，混合料不再使用。瀝青混合料的運輸： 瀝青混合料運輸用8T以上自卸汽車，運輸車的數(shù)量根據(jù)拌和站生產(chǎn)能力、運輸車速、運距等情況綜合考慮，合理配置。運輸車裝料前徹底清洗干凈，車箱底板及周壁涂一層油水混合液(柴油：水分為1：3)，但不在底板留存余液。自卸車箱后擋板卡扣每日保持清潔，易于卡緊、開啟，以防汽車在行進過程中漏料，造成材料浪費和路面污染。為了防止下雨對工程造成不良影響，各運輸車均備蓬布，一旦遇雨就及時覆蓋，以免造成材料浪費和溫度散失。瀝青混合料的攤鋪： 采用攤鋪機施工。攤鋪前，先對基層面進行調(diào)整，透層瀝青提前3天噴灑，

19、與其他構(gòu)造物的接觸面上，均勻地刷一薄層瀝青，然后放出中線及攤鋪邊線，并掛標高線以控制各層標高和厚度。攤鋪機就位，調(diào)整，檢測各部位參數(shù)及性能，然后按試驗路段獲得的數(shù)據(jù)進行作業(yè)。 攤鋪時，攤鋪機始終處于連續(xù)工作狀態(tài)和勻速前進，盡可能避免停機待料現(xiàn)象發(fā)生，以確保瀝青砼的攤鋪質(zhì)量均勻、平整、連續(xù)。攤鋪時，混合料的溫度控制在110一130的范圍內(nèi)，低溫施工時控制在120一140。對外型不規(guī)則、路面厚度不同、空間受到限制以及人工構(gòu)造物接頭等攤鋪機不能到達的和無法工作的地方，采用人工攤鋪。在攤鋪過程中，隨時檢查其寬度、厚度、平整度、路拱及溫度，對不合格之處及時予以調(diào)整。瀝青混合料的碾壓：壓的機械設(shè)備根據(jù)拌和

20、站的日產(chǎn)量、攤鋪速度及所取得的碾壓數(shù)據(jù)進行組合、配備，雙鋼輪壓路機一臺，膠輪壓路機一臺。碾壓時合理掌握碾壓溫度，壓實分初壓、復(fù)壓和終壓三個步驟進行，各作業(yè)段保持連續(xù)進行，各種壓路機的碾壓次序，碾壓遍數(shù)通過實驗確定，同時各壓路機嚴格按操作規(guī)程操作。初壓：用雙鋼輪壓路機靜壓2遍，速度15kmh，初壓溫度為110130。復(fù)壓：用三輪壓路機碾壓1遍，速度為3.5km/h,輪胎壓路機碾壓2遍，速度為4.0km/h,復(fù)壓溫度控制在90一110之間。終壓：用雙鋼輪壓路機靜壓1遍，速度為3.5km/h,終壓溫度控制在7090之間。特殊部位碾壓：（1）橫向接縫碾壓：橫向接縫的碾壓應(yīng)先用雙輪壓路機進行橫向碾壓，碾

21、壓帶的外側(cè)放置供壓路機行駛的墊木，碾壓時，壓路機位于已壓實的混合料層上，碾壓新鋪層的寬度為15cm。然后每壓一遍向新鋪混合料移動15-20cm，直至全部壓在新鋪層上為止，再改為縱向碾壓。 （2）彎道或交叉口的碾壓：先從彎道內(nèi)側(cè)或彎道較低一邊開始碾壓(以利于形成支承邊)。對急彎應(yīng)盡可能采取直線式碾壓(即缺角式碾壓)，并一轉(zhuǎn)換壓道，對缺角處用小型機具壓實。壓實中應(yīng)注意，轉(zhuǎn)向同速度要相吻合，盡可能用振動碾壓，以減少剪切力。 （3）陡坡碾壓：無論是上坡還是下坡，壓路機的從動輪始終朝著攤鋪方向，即從動輪在前，驅(qū)動輪在后(與一般路段碾壓時相反)。陡坡碾壓時，壓路機的起動、停止、變速要平穩(wěn)，避免速度過高或過

22、低，同時，要求瀝青混合料的溫度也不宜過高(取壓實時溫度范圍的下限為宜)。 接縫： 在基層的強度達到90以上，就可以進行瀝青碎石下面層的施工，施工時，采用半幅施工，首先進行右半幅的攤鋪，然后進行碾壓，當右半幅攤鋪碾壓100m時，進行另半幅的施工，調(diào)整好熨平板高度，預(yù)留壓實量，以便壓實到相同厚度，趁熱用鋼輪壓路機沿縫碾壓最后進行常規(guī)碾壓。橫向接縫施工工藝和縱向接縫相同，在施工過程中，瀝青碎石下面層、瀝青混凝土上面層的縱向接縫相互錯開，形成臺階型，絕對避免上下面層的縱向接縫在同一位置。詳見各層接縫位置示意圖： 路面各層接縫示意圖 瀝青砼上面層 瀝青砼面層縱向接縫 瀝青砼下面層 瀝青碎石層縱向接縫 1

23、5cm 路中線 氣候條件a、在陰雨的天氣和未預(yù)見的氣候突然變化，造成路面滯水時，瀝青混合料的攤鋪立刻停止。如未經(jīng)壓實即遭雨淋，瀝青混合料全部清除，更換新料。b、施工氣溫低于10時，停止攤鋪；當氣溫下降到15以下時，控制混合料的最大運距，保證碾壓溫度在規(guī)定的范圍以內(nèi)。四、施工進度計劃施工工序開工日期完工日期所用天數(shù)施工準備6.156.238鋪筑6.237.1523五、質(zhì)量保證措施工程質(zhì)量是工程之本，為確保工程質(zhì)量達到優(yōu)良標準，我們在施工中，將嚴格執(zhí)行施工技術(shù)規(guī)范和操作規(guī)程，用健全的質(zhì)量保證體系，嚴肅認真的工作態(tài)度，力爭創(chuàng)造一流的精品工程。1、嚴格按照設(shè)計圖紙和技術(shù)規(guī)范施工，不準偷工減料，弄虛作假

25、8、強化質(zhì)量意識，加強宣傳教育，把工程質(zhì)量保證意識做到人人皆知，個個自覺把好質(zhì)量關(guān)。七、安全保證措施a) 建立安全體系。項目經(jīng)理部成立了工地安全組，設(shè)專職安全員1名，各個分項負責人負責安全監(jiān)督，逐級明確安全責任制，責任到人。b) 建立各項安全制度，制定機械、車輛等技術(shù)操作規(guī)程，開展職工安全教育，獎罰分明，嚴格執(zhí)行安全監(jiān)督，防患于未然，杜絕事故發(fā)生。c) 施工現(xiàn)場采用標準化作業(yè)。根據(jù)指揮部施工中不中斷交通的要求，我們采取掛牌施工，在施工地段設(shè)警示牌，盡量注意交通安全。以安全為第一，合理組織生產(chǎn)。 .;the direct punishment 0.5-10,000 yuan, responsib
