1. Kev lees txais ntawm cov hauv paus hauv paus, tshuaj xyuas cov khoom siv, tshuab thiab khoom siv. Xyuas qhov flatness ntawm lub hauv paus txheej thiab yuav tsum tau tag nrho cov ntsuas kom tau raws li cov qauv kev tsim kho; tshawb xyuas qhov chaw, kom muaj nuj nqis, zoo, cia tej yam kev mob, thiab lwm yam ntawm raw khoom; tshawb xyuas qhov ua tau zoo thiab ntsuas qhov tseeb ntawm cov cuab yeej siv tsim kho kom ntseeg tau tias kev siv lub luag haujlwm.

2. Kev sim nteg cov seem xeem, txiav txim siab ntau yam ntsuas, thiab tsim cov phiaj xwm kev tsim kho. Qhov ntev ntawm qhov kev xeem yuav tsum yog 100M-200M. Thaum lub sij hawm tso, txiav txim siab kev sib xyaw ntawm cov tshuab, kev thauj khoom ceev ntawm cov khoom sib tov, tus nqi ntawm asphalt, paving ceev, dav thiab lwm yam ntsuas ntawm paver, thiab tsim ib qho kev npaj ua tiav.

3. Cov txheej txheem tsim kho, suav nrog kev sib xyaw, paving, dov, thiab lwm yam ntawm cov khoom sib tov. Sib tov cov asphalt nyob rau hauv asphalt mixing cog, siv ib tug loj-tonnage dump tsheb thauj cov sib tov mus rau qhov chaw, thiab kis tau cov sib tov ntawm lub hauv paus uas ua tau raws li cov kev cai. Tom qab paving ua tiav, depressurize asphalt pavement. Ua tib zoo saib rau paving thaum paving. siab.

4. Tom qab paving tiav lawm, cov asphalt pavement yog khaws cia thiab tuaj yeem qhib rau kev tsheb 24 teev tom qab. Cov pavement asphalt pavement yuav raug cais tawm kom tsis txhob muaj neeg thiab tsheb nkag mus, thiab nws tuaj yeem qhib rau siv tom qab 24 teev ntawm kev saib xyuas. Qhov kub ntawm cov paving tshiab asphalt yog qhov siab. Yog tias nws yuav tsum tau siv ua ntej, nchuav dej kom txias. Nws tsuas yog siv tau thaum qhov kub siab tshaj 50 ℃.
