Hloov cov khoom siv Asphalt yog ib txoj kev siv kev siv khoom. Txhawm rau kom zoo dua siv hom khoom siv no, cov neeg siv khoom lag luam yuav tsum paub txog cov yam ntxwv ua kom zoo ntawm txhua qhov sib xyaw thiab nkag siab nws txoj haujlwm. Tsuas yog nyob rau hauv txoj kev no tuaj yeem siv kev siv ib txwm ntawm cov khoom siv tau lees nyob rau hauv daim ntawv thov txhua hnub thiab nws txoj haujlwm yuav ua kom tiav.

I. Lub hauv paus rau kev faib tawm asphalt sib tov ua qauv /
/
tus qauv ntawm imphalt sib tov nroj tsuag feem ntau yog faib raws li peb yam: /
/
/
1. Muaj peev xwm ntau lawm: Raws li qhov loj ntawm cov peev txheej ntau lawm, asphalt sib xyaw ua ke tuaj yeem muab faib ua me me (/ teev) thiab ntau dua) ./
/
2. Cov yam ntxwv Assuctional: Cov qauv sib txawv ntawm asphalt sib xyaw cov nroj tsuag, xws li asphalt tso tawm system, thiab lwm yam.

I. Muaj peev xwm sib piv /
/
Me me xyaw nroj tsuag tuaj yeem ua tau 20- uas yog tsim nyog rau Lub Nroog thiab Cheeb Tsam Kev Kho Mob lossis Kev Kho Mob Sporadic; Cov nroj tsuag sib xyaw loj muaj lub peev xwm ntau tshaj 200 tons / teev, uas tuaj yeem ua tau raws li qhov kev xav tau ntawm kev siv kev siv ntau xws li kev loj. Thaum xaiv, nws yog ib qho tsim nyog los ua ke cov phiaj xwm phiaj xwm thiab qhov nruab nrab txhua hnub rau kev xam pom.

Txoj kev txhim kho cov kev cia siab ntawm asphalt sib tov cog yog qhov zoo heev, thiab cov khoom sib tw hauv kev ua lag luam kuj yog tsiv heev. Thaum cov khoom siv tau siv, tsis sib xws hnav ntawm cov log txhawb nqa thiab cov log tsheb feem ntau tshwm sim, thiab qee zaum qee qhov tsis txaus siab thiab lub ntsej muag pom kev tshwm sim. Qhov laj thawj tseem ceeb rau qhov no yog tias tom qab lub limhoo sib xyaw ua haujlwm rau ib lub sijhawm, nws lub nruas tshuab hluav taws xob yog qhov ntsuas kub thiab kev sib txhuam tau ntawm cov log thiab cov log tsheb.

Qhov tsis txaus ntseeg ntawm emulsified asphalt manifests nws tus kheej hauv peb daim ntawv: flocculation, agglomeration thiab sedimentation. Thaum emulsified asphalt hais tawg dhau los ntawm electrostatic repulsion ntawm ob lub hluav taws xob txheej thiab sib sau ua ke, nws yog hu ua flocculation. Nyob rau lub sijhawm no, yog tias kev siv tshuab stirring yog ua, cov asphalt hais tau tuaj yeem sib cais dua, uas yog cov txheej txheem rov qab. Tom qab flocculation, cov asphalt txhais uas sib sau ua ke ua ke ua ke ua ke rau hauv cov loj ephalt cuam tshuam, uas yog hu ua Agglomeration. Lub agglomerated asphalt meant tsis tuaj yeem sib cais los ntawm kev siv tshuab yooj yim, thiab cov txheej txheem no yog irreversible. Nrog rau kev nce ua txuas ntxiv ntawm agglomerated hais, qhov me me ntawm asphalt bastes me ntsis nce, thiab cov loj loj uas tau txiav txim siab nyob rau hauv kev txiav txim ntawm kev sib tsoo.

Feem ntau, cov khoom ua haujlwm ntawm cov asphalt mixing tsob nroj yog asphalt, tab sis yog tias muaj cov khoom siv yuav tsum tau tswj hwm? Cia kuv luv luv piav qhia rau koj yuav ua li cas tswj hwm cov asphalt sib tua cog hauv cov xwm txheej tshwj xeeb.
