Ukulawula izinga lokushisa kubaluleke kakhulu enqubweni yokulungiselela i-asphalt. Uma izinga lokushisa le-asphalt liphansi kakhulu, i-viscosity ye-asphalt izoba phezulu futhi i-ductility izobe inganele, okwenza i-emulsification ibe nzima. Uma izinga lokushisa le-asphalt liphezulu kakhulu, ngakolunye uhlangothi, lizobangela ukuguga kwe-asphalt, futhi ngakolunye uhlangothi, izinga lokushisa lokuphuma kwe-asphalt emulsified lizoba phezulu kakhulu, lithinte ukuzinza kwe-emulsifier kanye nekhwalithi ye-asphalt emulsified. .

Ngemuva kokuba imishini ye-asphalt e-emulsified isetshenziswe isikhathi eside, igebe le-emulsified asphalt colloid mill lizoba likhulu. Uma lesi simo senzeka, vele ulungise igebe mathupha. Kungenzeka futhi ukuthi kunenkinga ngetiyela. Ngokuvamile, imodeli ye-asphalt akufanele ishintshwe ngokujwayelekile ngesikhathi sokusetshenziswa okujwayelekile. Ama-asphalt ahlukene asebenzisa imithamo ehlukene ye-emulsifier, nayo ehlobene nezinga lokushisa. Ngokuvamile, lapho imodeli ye-asphalt iphansi, izinga lokushisa liphezulu. Okunye okungenzeka ukuthi inkinga ye-emulsifier. Izinkinga ngekhwalithi ye-emulsifier zizophinda zibangele ukuthi okokusebenza kwetiyela okufakwe emulsified kungasebenzi kahle. Kuye ngekhwalithi yamanzi, inani le-pH lingase lidinge ukulungiswa; kungenzeka ukuthi i-emulsifier incane noma izithako azikho ezingeni.
