進(jin)入冬(dong)季以來,為趕(gan)工(gong)期,由我公司施(shi)工(gong)的滁州(zhou)市X006線烏衣至廟張公路改建工(gong)程二(er)標段等項目正(zheng)在進(jin)行瀝青砼面層(ceng)的冬(dong)季施(shi)工(gong)。
依據《瀝(li)青路面施工(gong)(gong)(gong)及(ji)驗(yan)收規范》GB50092—96及(ji)《公路瀝(li)青路面施工(gong)(gong)(gong)技術(shu)規定(ding)(ding)》JTGF40—2004的規定(ding)(ding),我(wo)們制定(ding)(ding)了(le)針對性強的冬季施工(gong)(gong)(gong)方案,全(quan)面落實(shi)質(zhi)量管理(li)責任制,對可能(neng)遇(yu)到(dao)的各種情況制定(ding)(ding)相應的施工(gong)(gong)(gong)預案,加(jia)強工(gong)(gong)(gong)地現場與瀝(li)青拌和(he)站聯系,專(zhuan)人指(zhi)揮,統一調(diao)度,做到(dao)定(ding)(ding)量、定(ding)(ding)時、定(ding)(ding)車組(zu)織(zhi)供應,及(ji)時供料, 現場各種機械設備齊(qi)全(quan)。
同時,我(wo)們還制(zhi)定了一些技術措施和注意事項(xiang):
1、施工氣溫(wen)低(di)于5℃時,不得攤(tan)鋪碾壓熱拌瀝(li)青混合料;
2、風(feng)、雪、雨天氣不(bu)允許進行熱拌(ban)瀝青混合料路(lu)面施工;
3、晴天低溫時,確需施工(gong)時必須(xu)采取以下措施:
1)提高混(hun)合料的運輸(shu)、攤(tan)鋪、碾壓(ya)溫(wen)(wen)度(du)(du)。瀝青(qing)混(hun)合料的運輸(shu)溫(wen)(wen)度(du)(du)不得低于170℃,且(qie)(qie)不得超(chao)過185℃;攤(tan)鋪溫(wen)(wen)度(du)(du)為(wei)140℃~160℃,碾壓(ya)溫(wen)(wen)度(du)(du)為(wei)135℃~150℃,且(qie)(qie)不得低于110℃,碾壓(ya)終了溫(wen)(wen)度(du)(du)不低于70℃~80℃;
2)運料車必須采用棉被覆蓋保溫措施(shi);
3)采用(yong)高密實度攤鋪機,熨平板(ban)應(ying)加(jia)熱;
4)加強施工現場的測溫工作,做好測溫記錄(lu);
5)縮(suo)短攤鋪時間,隨攤隨壓,做好(hao)施工接(jie)縫處理。
