Txoj kev sab nraud uas muaj kev hloov pauv nrog kev hloov kho asphalt muaj qhov ruaj khov thiab hnav tsis muaj peev xwm, tsis muaj peev xwm ua tau muaj peev xwm ntau, thiab muaj ntau lub neej pabcuam ntawm txoj kev saum npoo.
Hloov kho emulsified cov khoom siv asphalt yog ib qho ntawm cov khoom siv uas tau siv rau lub sijhawm uas tsim khoom. Ua ntej cov khoom siv tau muab tso rau hauv kev siv, nws yuav tsum tau kuaj xyuas rau kev teeb tsa theem pib. Kuaj seb nws yog ib txwm, thiab tom qab ntawd muab tso rau hauv kev siv. Ntawm no, Duxiu yuav qhia txog kev tshuaj xyuas ntawm hloov emulsified emulsified khoom:

Ua ntej, tshuaj xyuas cov hloov kho emulsifier ntawm hloov emulsified urulth khoom siv. Yog hais tias qhov sib txawv ntawm emulsified asphalt bolthal zeb ntawm emulsifier siv rau lub sijhawm ntev yuav loj dua, ces peb yuav tsum tau hloov kho lub sijhawm no mus txuas ntxiv. Qhov no yog qhov teeb meem yooj yim.
Soj ntsuam qhov teeb meem ntawm kev hloov kho. Feem ntau, tus nqi ntawm cov hloov kho hloov kho ntxiv yuav tsum yog qhov chaw. Thaum ntxiv, tus nqi PH yuav tsum raug hloov kho raws li cov dej sib txawv. Qhov teeb meem no xav tau cov neeg ua haujlwm tshaj lij los soj ntsuam. Lwm qhov ua tau yog tias qhov hloov kho emulsified evulthify cov khoom nws tus kheej muaj teeb meem. Vim tias cov neeg asphalt kuj muaj cov kev sib tw Asphalt, thaum ua tau zoo los them nyiaj rau seb puas muaj cov khoom siv asphalt thiab xyuas kom zoo.
