Cov hau kev thiab cov kauj ruam: /
/
1. Kev npaj ua haujlwm: ua ntej kev tsim kho pib, txoj kev xav tau npaj. Qhov no suav nrog kev ntxuav cov khib nyiab thiab hmoov av ntawm txoj kev pavement thiab kom ntseeg tau tias txoj kev pavement yog tiaj./
/
2. Kev kho mob: ua ntej kev tsim kho ua ntej, lub hauv paus yuav tsum tau kho. Qhov no yuav suav nrog txhaws cov pa roj pleev thiab kho kom tawg, thiab ua kom muaj kev ruaj ntseg thiab tiaj tus ntawm lub hauv paus.

1. Cov paving kub ntawm Asphalt pavement feem ntau 135 ~ 175 ℃. Ua ntej paving txoj kev limhiam, nws yog ib qho tsim nyog los tshem tawm cov khib nyiab ntawm lub hauv paus kev cai kom ntseeg tau tias kev pua lub hauv paus yog qhuav thiab huv. Nyob rau tib lub sijhawm, nws yog ib qho tsim nyog los xyuas kom meej qhov ceev thiab tuab ntawm lub hauv paus, uas lays yog qhov tseem ceeb ntawm asphalt paving.

Kev ntxuav cov txhab txiag ntawm cov loj asphalt loj yog ib feem tseem ceeb ntawm kev ua kom zoo thiab ua haujlwm lub neej. Kev ua haujlwm huv yuav tsum ua kom ceevfaj thiab txhij txhua. Cov hauv qab no piav qhia kom ntxuav nws li cas los ntawm ntau yam:

Hauv emulsified asphalt, pH nqi tseem muaj qee yam cuam tshuam rau cov demulsification tus nqi. Ua ntej kev kawm txog qhov cuam tshuam ntawm PH ntawm kev rhuav tshem tus nqi ntawm emulsified aschhalify ntawm anionic emulsified asulhalt yog piav qhia rau feem.

Tsis ntev los no, nws tau pom tias muaj coob tus neeg tsis paub ntau txog cov ntsiab lus txhua hnub ntawm kev txawj ntse emulsified cov tshuaj ntsuab. Yog tias koj tseem xav paub tias dab tsi tshwm sim, koj tuaj yeem nyeem cov ntsiab lus hauv qab no emulsified asphalt cov khoom siv yog nyob rau hauv kev ua teb ntawm kev txij nkawm. Lawv cov txij nkawm txhua hnub yog qhov tseem ceeb thiab tuaj yeem txuas qhov kev pabcuam lub neej ntawm cov khoom siv thiab xyuas kom muaj kev ua haujlwm zoo thiab zoo. Cov hauv qab no qhia cov ntsiab lus txhua hnub ntawm kev txawj ntse emulsified asphalt rov qab los ntawm plaub yam:

Sib Txawv Ntau Hom Emulsified Hloov Cov Khoom Siv Asphalt muaj kev pabcuam sib txawv. Piv txwv li, muaj qhov sib txawv ntawm lub neej kev pabcuam ntawm cov sib quas ntus emulsifiers thiab nruam emulsifiers. Ib qho ntxiv, kev siv ib puag ncig cov khoom siv tseem yuav cuam tshuam nws lub neej. Piv txwv li, cov chaw hnyav ib puag ncig xws li cov cua sov siab, siab dua, thiab txias yuav ua rau cov khoom siv rau hnub nyoog sai dua. Yog li ntawd, thaum tsim kev cai lub neej kev pab, nws yog ib qho tsim nyog los xav txog hom khoom siv thiab kev siv ib puag ncig.
