進(jin)入冬(dong)季(ji)以來,為趕工(gong)期,由(you)我公(gong)司施工(gong)的(de)滁州(zhou)市X006線烏衣至廟(miao)張公(gong)路改建工(gong)程二標(biao)段等(deng)項(xiang)目正在進(jin)行瀝青砼面層(ceng)的(de)冬(dong)季(ji)施工(gong)。
依據(ju)《瀝青路(lu)面施工(gong)(gong)及驗收規范》GB50092—96及《公路(lu)瀝青路(lu)面施工(gong)(gong)技(ji)術(shu)規定(ding)》JTGF40—2004的規定(ding),我(wo)們制定(ding)了針對性強的冬季施工(gong)(gong)方案,全面落實質量(liang)管理責任制,對可能遇到(dao)的各(ge)種情況制定(ding)相應的施工(gong)(gong)預(yu)案,加(jia)強工(gong)(gong)地現(xian)場(chang)與(yu)瀝青拌和(he)站聯系(xi),專人指揮,統一調度(du),做到(dao)定(ding)量(liang)、定(ding)時、定(ding)車組織供應,及時供料, 現(xian)場(chang)各(ge)種機(ji)械設備(bei)齊全。
同時,我們(men)還制定(ding)了一些(xie)技(ji)術(shu)措施和(he)注意(yi)事項:
1、施(shi)工氣溫低于5℃時,不得攤鋪碾壓熱拌(ban)瀝青混合料;
2、風(feng)、雪、雨天氣(qi)不允許進行熱拌瀝青混(hun)合料(liao)路面施(shi)工;
3、晴天低溫時,確需施(shi)工時必須采取(qu)以(yi)下措施(shi):
1)提高混合料的(de)運(yun)輸、攤鋪、碾(nian)壓(ya)(ya)溫(wen)(wen)(wen)(wen)度(du)(du)。瀝青混合料的(de)運(yun)輸溫(wen)(wen)(wen)(wen)度(du)(du)不(bu)得低于170℃,且(qie)不(bu)得超(chao)過185℃;攤鋪溫(wen)(wen)(wen)(wen)度(du)(du)為(wei)140℃~160℃,碾(nian)壓(ya)(ya)溫(wen)(wen)(wen)(wen)度(du)(du)為(wei)135℃~150℃,且(qie)不(bu)得低于110℃,碾(nian)壓(ya)(ya)終了溫(wen)(wen)(wen)(wen)度(du)(du)不(bu)低于70℃~80℃;
2)運(yun)料(liao)車(che)必須采(cai)用棉被(bei)覆(fu)蓋保(bao)溫措(cuo)施;
3)采用高(gao)密實(shi)度攤鋪機,熨平板應(ying)加(jia)熱;
4)加強施工現場的測(ce)(ce)溫工作,做好測(ce)(ce)溫記錄;
5)縮(suo)短攤鋪時間(jian),隨攤隨壓,做好施工接(jie)縫處(chu)理(li)。
