1. Cia kub
Feem ntau hais lus, qhov tsim nyog qhov kub thiab txias ntawm asphalt hauv cov tso tsheb hlau luam yog li 120 degree txog 140 degree. Nyob rau hauv qhov ntsuas kub no, asphalt tuaj yeem tswj cov dej ntws zoo thiab yooj yim rau twj thiab siv. Yog tias qhov kub thiab txias qis dhau, cov asphalt yuav khov, cov kua dej yuav deteriorate, thiab nws tseem tuaj yeem ua kom khov, cuam tshuam rau kev siv tom ntej; hos yog hais tias qhov kub thiab txias heev, nws yuav ua rau asphalt aging, kev ua hauj lwm degradation, thiab ua rau kom lub zog noj thiab muaj kev nyab xeeb txaus ntshai.
2. Sab saum toj txwv ntawm cua sov
Thaum nws yog ib qho tsim nyog los ua kom sov asphalt hauv lub tank cia, qhov cua sov yuav tsum tsis txhob ntau tshaj 180 degree. Tshaj qhov kub no, asphalt yuav dhau-hnub nyoog, hlawv, thiab lwm yam, cuam tshuam rau nws qhov kev ua tau zoo thiab zoo.
Nws yuav tsum raug sau tseg tias ntau hom asphalt thiab kev siv sib txawv yuav muaj qee yam cuam tshuam rau qhov kub thiab txias ntawm lub tank cia. Nyob rau tib lub sijhawm, hauv kev ua haujlwm tiag tiag, qhov kub ntawm lub tank yuav tsum tau tswj nruj me ntsis raws li qhov xwm txheej tshwj xeeb kom ntseeg tau tias qhov zoo thiab kev nyab xeeb ntawm asphalt.
