mprove the pavement smoothness, surface layer should adopt the sled type of paving the same elevation difference before and after paving thickness control mode. Due to large SBS asphalt viscosity, adhesion strength is strong, with some after sled is rubbertired structure of paver, roller easy adhesion mixture of fine particles, affect the flatness, so after the paver sled is a rubbertired structure sliding boots must change to steel structure. Paving speed should be controlled in 2 m/min, do it slowly, uniform, continuous uninterrupted paving, ban transform speed or stop at will. Improve the preloading pactness in the process of paving. SBS modified asphalt mixture under high temperature condition is mainly rely on embedded squeeze effect of coarse aggregate, can be appropriately increase rammer vibrating frequency, reduce the residual pacting factor, the trace of the initial pressure and tiny, further ensure the final pavement roughness. 3,the specification requirement rolled The proper rolling temperature range is 130 ℃ to 150 ℃, its final rolling temperature is not lower than 110 ℃. The SBS asphalt mixture pacting process in line with the following principles: according to keep up with, slow pressure, high frequency, lowrising rolling of eight lines rolling roller must keep up with the back of the paver, only under the condition of high temperature rolling can achieve better effect, paction speed control in 4 to 5 km/h. Rolling speed is balanced, back when close the vibration, the direction to gradually change, no twist curved to walk, for each rolling start or finish a bit twisted rolling, eliminate the rolling wheel track joint. Must not be allowed on the new layer asphalt mixture about steering, switching, mobile location. All of a sudden braking or stop to rest, through the first and second contract section of SBS asphalt south road test section, determine the paction process for DD110 or DD130 roller 23 gear rolling 3 times each, namely 1 times at the beginning of highfrequency lowrising vibration rolling 2 times, 2 times. Special note: if found during the construction of roller sticky wheel, better with detergent water,4. the quality control of the asphalt mixture of SBSTo one floor of mixture asphalt, the debulk result of the scene should adopt the spacerate and press the solidity to control is subject to that survey every day to calculate the largest density of theory needed in space rate, is it go on according to” asphalt road surface mixture heavy relative density test (vacuum law) (T071193) most to test. The onthespot asphalt mixture space rate is 3%6%.One layer of Surface presses the inspection of the solidity, that survey the core kind serves as the standard.原創(chuàng)性聲明本人鄭重承諾:所呈交的畢業(yè)設(shè)計(jì)(論文) ,是我個(gè)人在指導(dǎo)教師的指導(dǎo)下進(jìn)行的研究工作及取得的成果。盡我所知,除文中特別加以標(biāo)注和致謝的地方外,不包含其他人或組織已經(jīng)發(fā)表或公布過(guò)的研究成果,也不包含我為獲得 及其它教育機(jī)構(gòu)的學(xué)位或?qū)W歷而使用過(guò)的材料。對(duì)本研究提供過(guò)幫助和做出過(guò)貢獻(xiàn)的個(gè)人或集體,均已在文中作了明確的說(shuō)明并表示了謝意。作 者 簽 名: 日 期: 指導(dǎo)教師簽名: 日 期: 使用授權(quán)說(shuō)明本人完全了解 大學(xué)關(guān)于收集、保存、使用畢業(yè)設(shè)計(jì)(論文)的規(guī)定,即:按照學(xué)校要求提交畢業(yè)設(shè)計(jì)(論文)的印刷本和電子版本;學(xué)校有權(quán)保存畢業(yè)設(shè)計(jì)(論文)的印刷本和電子版,并提供目錄檢索與閱覽服務(wù);學(xué)??梢圆捎糜坝?、縮印、數(shù)字化或其它復(fù)制手段保存論文;在不以贏利為目的前提下,學(xué)??梢怨颊撐牡牟糠只蛉?jī)?nèi)容。作者簽名: 日 期: 學(xué)位論文原創(chuàng)性聲明本人鄭重聲明:所呈交的論文是本人在導(dǎo)師的指導(dǎo)下獨(dú)立進(jìn)行研究所取得的研究成果。除了文中特別加以標(biāo)注引用的內(nèi)容外,本論文不包含任何其他個(gè)人或集體已經(jīng)發(fā)表或撰寫的成果作品。對(duì)本文的研究做出重要貢獻(xiàn)的個(gè)人和集體,均已在文中以明確方式標(biāo)明。本人完全意識(shí)到本聲明的法律后果由本人承擔(dān)。作者簽名: 日期: 年 月 日學(xué)位論文版權(quán)使用授權(quán)書本學(xué)位論文作者完全了解學(xué)校有關(guān)保留、使用學(xué)位論文的規(guī)定,同意學(xué)校保留并向國(guó)家有關(guān)部門或機(jī)構(gòu)送交論文的復(fù)印件和電子版,允許論文被查閱和借閱。本人授權(quán) 大學(xué)可以將本學(xué)位論文的全部或部分內(nèi)容編入有關(guān)數(shù)據(jù)庫(kù)進(jìn)行檢索,可以采用影印、縮印或掃描等復(fù)制手段保存和匯編本學(xué)位論文。涉密論文按學(xué)校規(guī)定處理。作者簽名: 日期: 年 月 日導(dǎo)師簽名: 日期: 年 月 日注 意 事 項(xiàng)(論文)的內(nèi)容包括:1)封面(按教務(wù)處制定的標(biāo)準(zhǔn)封面格式制作)2)原創(chuàng)性聲明3)中文摘要(300 字左右) 、關(guān)鍵詞4)外文摘要、關(guān)鍵詞 5)目次頁(yè)(附件不統(tǒng)一編入)6)論文主體部分:引言(或緒論) 、正文、結(jié)論7)參考文獻(xiàn)8)致謝9)附錄(對(duì)論文支持必要時(shí)):理工類設(shè)計(jì)(論文)正文字?jǐn)?shù)不少于 1 萬(wàn)字(不包括圖紙、程序清單等) ,文科類論文正文字?jǐn)?shù)不少于 萬(wàn)字。:任務(wù)書、開(kāi)題報(bào)告、外文譯文、譯文原文(復(fù)印件) 。、圖表要求:1)文字通順,語(yǔ)言流暢,書寫字跡工整,打印字體及大小符合要求,無(wú)錯(cuò)別字,不準(zhǔn)請(qǐng)他人代寫2)工程設(shè)計(jì)類題目的圖紙,要求部分用尺規(guī)繪制,部分用計(jì)算機(jī)繪制,所有圖紙應(yīng)符合國(guó)家技術(shù)標(biāo)準(zhǔn)規(guī)范。圖表整潔,布局合理,文字注釋必須使用工程字書寫,不準(zhǔn)用徒手畫3)畢業(yè)論文須用 A4 單面打印,論文 50 頁(yè)以上的雙面打印4)圖表應(yīng)繪制于無(wú)格子的頁(yè)面上5)軟件工程類課題應(yīng)有程序清單,并提供電子文檔1)設(shè)計(jì)(論文)2)附件:按照任務(wù)書、開(kāi)題報(bào)告、外文譯文、譯文原文(復(fù)印件)次序裝訂3)其它
