樂自高速長山隧道路面提升工程提前完工

歷(li)時13天晝夜(ye)不(bu)間斷施工(gong)(gong)，10月29日，樂(le)自高速長山(shan)隧道路(lu)面(mian)提升工(gong)(gong)程(cheng)順利完工(gong)(gong)通車。

樂自(zi)高(gao)速長山隧道(dao)(dao)路面(mian)提(ti)升改造是對隧道(dao)(dao)進(jin)行(xing)“白改黑(hei)”瀝青(qing)(qing)罩面(mian)處治，工(gong)(gong)(gong)期30天(tian)，合(he)同金額(e)1665萬元。建(jian)設過程(cheng)中(zhong)，由于長山特長隧道(dao)(dao)單(dan)洞施工(gong)(gong)(gong)長達8574米，并且采用(yong)SBS瀝青(qing)(qing)瑪蹄(ti)脂碎石混合(he)料面(mian)層(ceng)(ceng)+瀝青(qing)(qing)砂找(zhao)平層(ceng)(ceng)+高(gao)黏瀝青(qing)(qing)膠粘結層(ceng)(ceng)的(de)路面(mian)結構形式，工(gong)(gong)(gong)期緊迫、工(gong)(gong)(gong)藝(yi)復雜。在確保人員安全(quan)和工(gong)(gong)(gong)程(cheng)質量的(de)前(qian)(qian)提(ti)下，項目部(bu)爭分(fen)奪(duo)秒，搶抓時限(xian)，全(quan)力(li)推進(jin)工(gong)(gong)(gong)程(cheng)建(jian)設，提(ti)前(qian)(qian)17天(tian)完成了施工(gong)(gong)(gong)任務，并開展了“基于長山隧道(dao)(dao)路面(mian)抗滑性能提(ti)升的(de)高(gao)黏瀝青(qing)(qing)薄(bo)層(ceng)(ceng)罩面(mian)施工(gong)(gong)(gong)關(guan)鍵(jian)技術研究”科研項目，受到業主的(de)高(gao)度評價。
