Thaum siv nyob rau hauv lub ntuj ib puag ncig, Asphalt yuav muaj hnub nyoog thiab nws qhov kev ua tau zoo yuav tsis kam vim yog lub teeb, oxygen, thiab kub.Bitumen emulsifierstuaj yeem txhim kho nws txoj kev tawm tsam kev ua haujlwm rau qee yam.
Ntawm ib sab tes, ib qho tsim nyog li asphalt emulsifier tuaj yeem ua tus qauv ruaj khov rau hauv asphalt.

Txawm li cas los xij, ntau hom thiab ntau npaum li cas ntawm bitumen emulsifiers muaj cov teebmeem sib txawv. Tsuas yog xaiv cov emulsifier tsim nyog thiab siv nws tsim nyog tuaj yeem ua kom zoo dua qub, thiab qhov ua tau zoo thiab ruaj khov thiab lwm yam haujlwm tau lees.
