Txhua tus neeg yuav muaj qee qhov kev paub txog kev siv asphalt cua sov tso tsheb hlau luam. Niaj hnub no, peb yuav qhia qee yam tsis ruaj khov uas tshwm sim thaum asphalt cua sov tso tsheb hlau luam ua haujlwm. Cia wb mus saib lawv ua ke.
Muaj peb qhov kev tshwm sim tseem ceeb ntawm qhov tsis ruaj khov ntawm emulsified asphalt tsim los ntawm asphalt cua sov tso tsheb hlau luam: inclined phaj sedimentation tank, coalescer thiab lub hauv paus kev sib hais haum. Lub asphalt cia tank siv L-band tshav kub (high-temperature heat transfer oil) raws li lub tshav kub hloov mus rau nruab nrab, raw thee, natural gas or oil furnace as the heat source, and the hot oil pump is forced to circulate system to heat. asphalt rau qhov ntsuas kub.

Asphalt cua sov tso tsheb hlau luam tseem hu ua cov yeeb yuj binders. Lawv tab tom xyaum hloov cov khoom xyaw asphalt thiab yog ua los ntawm cov roj av resins thiab SBS hloov cov ntaub ntawv thiab lwm yam ntaub ntawv raw khoom. Hom asphalt no nws tus kheej tsis muaj xim lossis tsis muaj xim, tab sis tsaus liab. Nyob rau hauv xyoo tas los no, nws tau nquag hu ua cov xim asphalt pavement vim kev lag luam cwj pwm. Lub asphalt cua sov tank lov lub electrostatic induction (tus nqi zoo nyob rau hauv lub xeev zoo li qub) repulsion ntawm ob txheej hluav taws xob thiab sib sau ua ke, uas yog hu ua inclined phaj sedimentation tank. Nyob rau lub sijhawm no, ntev npaum li cov neeg kho tshuab nplawm yog nqa tawm, asphalt cua sov tank hais tuaj yeem sib cais dua. Nws yog ib qho txheej txheem thim rov qab.
Cov emulsified asphalt hais sib sau ua ke tom qab lub asphalt cua sov tank inclined phaj sedimentation tank yog fused rau hauv ib tug loj-loj asphalt cua sov tank hu ua agglomerator. Cov emulsified asphalt particles uas tsim cov agglomeration tsis tuaj yeem sib cais los ntawm cov tshuab ua kom yooj yim. Cov txheej txheem no yog irreversible.
Nrog rau kev nce ntxiv ntawm asphalt cua sov tso tsheb hlau luam, qhov loj me me ntawm asphalt cua sov tso tsheb hlau luam tau maj mam nce, thiab qhov loj-loj asphalt cua sov tso tsheb hlau luam tau nyob hauv qhov kev txiav txim ntawm kev quab yuam. Yuav kom khaws cov asphalt cua sov tank kom zoo dua qub, nws yog ib qho tsim nyog kom tsis txhob muaj peb hom kev tsis ruaj khov ntawm inclined phaj sedimentation tank, agglomerator thiab kev sib haum xeeb ntawm emulsified asphalt.
