After laying, the layer thickness shall be checked and make any adjustment if necessary.碾壓：瀝青混合料的碾壓，壓實(shí)采用400kg壓路機(jī)，在終壓溫度前消除

52、人為全部軌跡，達(dá)到設(shè)計(jì)要求的厚度即停止作業(yè)，以免過壓。先攤鋪第一層瀝青砂，厚度大約40mm，并在模板上做出標(biāo)記。攤鋪均勻后，用400kg壓路機(jī)壓實(shí)，壓路機(jī)無法壓實(shí)的區(qū)域采用人工夯實(shí)。第一層施工完畢，經(jīng)SEPCO、PMC、BSC驗(yàn)收后方可進(jìn)行第二層施工。然后按第一層瀝青砂鋪設(shè)厚度與壓實(shí)厚度之比攤鋪第二層瀝青砂，使壓實(shí)后標(biāo)高達(dá)到設(shè)計(jì)標(biāo)高。中心點(diǎn)半球型將使用球形鐵板壓實(shí)成型。對(duì)于接茬處應(yīng)將瀝青砂層鏟成斜面，使接茬相互搭接,上層接茬縫與下層接茬縫必須錯(cuò)開，防止裂縫。上下層間接茬前也應(yīng)噴灑一層熱瀝青。最后人工平整使碾壓達(dá)到7.5.2.1中質(zhì)量標(biāo)準(zhǔn)的要求。施工中每隔30分鐘進(jìn)行一次測溫，并進(jìn)行詳細(xì)測溫記錄。每車瀝青砂測溫點(diǎn)5個(gè)，中心一個(gè)，每個(gè)邊角一個(gè)，共5個(gè)。修補(bǔ)瀝青砂溫度必須大于100攝氏度，施工
