Dab tsi yuav tsum tau them nyiaj mloog rau hauv kev tswj qhov kub thiab txias thaum lub sij hawm tsim kho asphalt pavement?
1. Cov paving kub ntawm asphalt pavement feem ntau yog 135 ~ 175 ℃. Ua ntej pavement asphalt pavement, nws yog ib qho tsim nyog yuav tsum tshem tawm cov khib nyiab ntawm lub hauv paus pavement kom ntseeg tau tias lub hauv paus pavement qhuav thiab huv si. Nyob rau tib lub sijhawm, nws yog ib qho tsim nyog los xyuas kom meej qhov kev sib haum xeeb ntawm qhov ntom thiab tuab ntawm lub hauv paus pavement, uas yog ib qho tseem ceeb ntawm qhov chaw rau asphalt paving.
2. Qhov kub ntawm qhov kev sib txuas ntawm qhov pib siab feem ntau yog 110 ~ 140 ℃. Tom qab pib lub siab, cov neeg ua haujlwm tseem ceeb yuav tsum tau kuaj xyuas qhov tiaj tus thiab txoj kev koov ntawm txoj kev pavement, thiab kho cov teeb meem tam sim ntawd. Yog tias muaj qhov hloov pauv tshwm sim thaum lub sijhawm pavement dov, koj tuaj yeem tos kom txog thaum qhov kub thiab txias ua ntej dov. Yog tias muaj kab nrib pleb tshwm sim, xyuas qhov ua rau thiab kho cov kev ntsuas hauv lub sijhawm.
3. Qhov kub ntawm qhov txuas rov qab yog feem ntau 120 ~ 130 ℃. Tus naj npawb ntawm rollings yuav tsum ntau tshaj 6 zaug. Tsuas yog nyob rau hauv txoj kev no tuaj yeem lav qhov ruaj khov thiab ruaj khov ntawm txoj kev pavement.
4. Qhov kub ntawm qhov kawg ntawm qhov kawg siab yuav tsum siab tshaj 90 ℃. Lub siab kawg yog cov kauj ruam kawg kom tshem tawm cov cim log, qhov tsis xws luag thiab xyuas kom meej tias cov txheej txheej saum npoo muaj qhov flatness zoo. Txij li thaum qhov kawg compaction yuav tsum tau tshem tawm qhov tsis sib xws ntawm cov txheej txheej saum npoo thaum lub sij hawm rov ua kom rov ua haujlwm thiab xyuas kom meej qhov flatness ntawm txoj kev nto, cov asphalt sib tov kuj yuav tsum tau xaus lub compaction ntawm ib tug kuj siab, tiam sis tsis heev compaction kub.
