Tam sim no, asphalt pavement tau siv dav hauv kev kev tsim kev vim nws cov txiaj ntsig ntau. Tam sim no, peb tsuas yog siv kub bitumen thiab emulsified bitumen nyob rau hauv kev tsim txom ntawm asphalt pavement. Kub bitumen noj ntau ntau lub zog, tshwj xeeb tshaj yog cov khoom siv ntawm cov xuab zeb thiab cov ntaub ntawv gravel uas xav tau cov cua sov. Cov chaw tsim kho kom muaj cov neeg ua haujlwm tsis zoo thiab siv zog yog siab. Thaum siv emulsified bitumen rau kev tsim kho, cua sov tsis tas thiab nws tuaj yeem muab txau lossis sib xyaw ua ke los yog sib xyaw rau hauv chav sov, thiab cov qauv ntawm ntau yam qauv tuaj yeem raug pua. Ntxiv mus, emulsified bitumen tuaj yeem ntws los ntawm nws tus kheej ntawm chav tsev kub, thiab tuaj yeem ua rau hauv emulsified bitumen ntawm ntau lub siab raws li xav tau. Nws yog ib qho yooj yim kom ua tiav cov yeeb yaj kiab asphalt los ntawm pouring lossis permeating txheej txheej, uas tsis tuaj yeem ua tiav los ntawm kub bitumen. Nrog maj mam txhim kho ntawm txoj kev network thiab cov kev xav tau ntawm txoj kev qis-qib, kev siv ntawm epulsified bitumen yuav tau loj dua thiab loj dua; Nrog rau kev txhim kho ntawm ib puag ncig ib puag ncig thiab kev sib kis tsis txaus ntseeg, cov feem ntawm emulsified bitphalt yuav dhau los thiab siab dua. Lub luag ntawm kev siv yuav kuj ua neeg dav thiab dav, thiab qhov zoo yuav dhau los ua neeg zoo dua thiab zoo dua. Emulsified Bitumen muaj cov yam ntxwv ntawm cov tsis muaj tshuaj lom, tsis muaj ntxhiab, tsis muaj nplaim taws, ziab kom qhuav thiab ua kom nrawm nrawm thiab ua kom nrawm. Nws tsis tuaj yeem txhim kho txoj hauv kev zoo, nthuav cov kev tsim kho ntawm asphalt siv, nthuav ib puag ncig cov pa phem thiab txhim kho cov haujlwm tsim kho, tab sis kuj txuag lub zog thiab cov ntaub ntawv.
Emulsified Bitumen yog tsuas yog tsim ntawm bitumen, emulsifier, stabilizer thiab dej.
1. Bitumen yog cov khoom tseem ceeb ntawm emulsified bitumen. Qhov zoo ntawm asphalt yog ncaj qha cuam tshuam nrog kev ua tau zoo ntawm emulsified asphalt.
2. Emulsifier yog cov khoom tseem ceeb hauv kev tsim ntawm emulsified asphalt, uas txiav txim siab qhov zoo ntawm emulsified asphalt.
3. Lub stabilizer tuaj yeem ua rau lub emulsified asphalt muaj cov khoom tso ruaj ruaj thaum lub sijhawm tsim kho.
4. Feem ntau yog feem ntau yuav tsum tau tias cov dej ua tau zoo yuav tsum tsis txhob nyuaj thiab yuav tsum tsis txhob muaj lwm yam impurities. Tus lej pH tus nqi ntawm cov dej thiab calcium thiab cov ntshav khov si muaj kev cuam tshuam rau emulsification.
Nyob ntawm cov ntaub ntawv thiab emulsifiers siv, kev ua tau zoo thiab siv cov aspulsified asphalt kuj sib txawv. Cov neeg asphalt, SBL Mev tawg paj, sbr hloov emulsify emulthalt, siab siab lub siab viscosity emultified evult. Hauv kev tsim kho thiab txij nkawm ntawm asphalt pavement, tsim nyog emulsified asphal yuav raug xaiv rau kev mob thiab cov khoom.
