Ukulawula ubushushu kubaluleke kakhulu kwinkqubo yokulungiselela i-asphalt. Ukuba ubushushu be-asphalt buphantsi kakhulu, i-asphalt viscosity iya kuba phezulu kwaye i-ductility ayiyi kuba yanele, okwenza ukuba i-emulsification ibe nzima. Ukuba ubushushu be-asphalt buphezulu kakhulu, kwelinye icala, luya kubangela ukuguga kwe-asphalt, kwaye kwelinye icala, ukushisa kwe-asphalt ye-emulsified kuya kuba phezulu kakhulu, kuchaphazela ukuzinza kwe-emulsifier kunye nomgangatho we-asphalt e-emulsified. .

Emva kokuba isixhobo se-asphalt esine-emulsified sisetyenziswe ixesha elide, i-gap ye-emulsified asphalt colloid mill iya kuba nkulu. Ukuba le nto iyenzeka, vele ulungelelanise isithuba ngesandla. Kusenokwenzeka ukuba kukho ingxaki kwi-asphalt. Ngokuqhelekileyo, imodeli ye-asphalt akufanele iguqulwe ngokungaqhelekanga ngexesha lokusetyenziswa okuqhelekileyo. Ii-asphalts ezahlukeneyo zisebenzisa iidosi ezahlukeneyo ze-emulsifier, ezihambelana nobushushu. Ngokuqhelekileyo, imodeli ye-asphalt isezantsi, iqondo lokushisa liphezulu. Enye into enokwenzeka yingxaki ye-emulsifier. Iingxaki kumgangatho we-emulsifier nazo ziya kubangela ukuba izixhobo ze-asphalt ezifakwe emulsified zingasebenzi kakuhle. Ngokuxhomekeke kumgangatho wamanzi, ixabiso le-pH lisenokufuna ukulungiswa; mhlawumbi i-emulsifier ingaphantsi okanye izithako azikho kumgangatho.
