Kev tswj qhov kub thiab txias yog qhov tseem ceeb heev hauv kev npaj asphalt. Yog tias qhov kub asphalt qis dhau lawm, asphalt viscosity yuav siab thiab cov ductility yuav tsis txaus, ua rau emulsification nyuaj. Yog tias qhov kub asphalt siab dhau lawm, ntawm ib sab, nws yuav ua rau asphalt aging, thiab ntawm qhov tod tes, qhov hluav taws xob kub ntawm emulsified asphalt yuav siab dhau, cuam tshuam rau kev ruaj ntseg ntawm emulsifier thiab qhov zoo ntawm emulsified asphalt. .
Tom qab cov khoom siv emulsified asphalt tau siv rau lub sijhawm ntev, qhov sib txawv ntawm emulsified asphalt colloid zeb yuav loj dua. Yog tias qhov tshwm sim no tshwm sim, tsuas yog kho qhov sib txawv manually. Nws kuj tseem yuav muaj teeb meem nrog asphalt. Feem ntau, cov qauv asphalt yuav tsum tsis txhob hloov pauv thaum siv ib txwm. Asphalts sib txawv siv cov tshuaj emulsifier sib txawv, uas kuj muaj feem xyuam rau qhov kub thiab txias. Feem ntau hais lus, tus qauv asphalt qis dua, qhov kub siab dua. Lwm qhov ua tau yog qhov teeb meem ntawm emulsifier. Teeb meem nrog qhov zoo ntawm emulsifier kuj tseem yuav ua rau cov khoom siv asphalt emulsified ua haujlwm tsis zoo. Nyob ntawm cov dej zoo, tus nqi pH kuj yuav tsum tau kho; txawm tias cov emulsifier tsawg dua los yog cov khoom xyaw tsis yog raws li tus qauv.
