Emulsified bitumen na-abụkarị nke bitumen, emulsifier, stabilizer na mmiri.
1. Bitumen bụ isi ihe nke emulsified bitumen. Àgwà nke asphalt metụtara kpọmkwem na arụmọrụ nke emulsified asphalt.
2. Emulsifier bụ ihe dị mkpa na nhazi nke emulsified asphalt, nke na-ekpebi àgwà nke emulsified asphalt.
3. The stabilizer nwere ike ime ka emulsified asphalt nwere ezigbo nchekwa nchekwa n'oge usoro ihe owuwu.
4. A na-achọkarị ka ogo mmiri ghara ịdị oke ike ma ghara inwe adịghị ọcha ndị ọzọ. Uru pH nke mmiri na calcium na magnesium plasma nwere mmetụta na emulsification.
Dabere na ihe na emulsifiers eji, arụmọrụ na ojiji nke emulsified asphalt dịkwa iche. Ndị a na-ejikarị eme ihe bụ: asphalt emulsified nkịtị, SBS gbanwetụrụ emulsified asphalt, SBR modified emulsified asphalt, extra slow cracking emulsified asphalt, elu permeability emulsified asphalt, elu itinye uche High viscosity emulsified asphalt. Na-ewu na mmezi nke pavement asphalt, e nwere ike họrọ emulsified asphalt kwesịrị ekwesị dị ka ọnọdụ okporo ụzọ na ihe onwunwe si dị.
