Emulsified asphalt paving emepụtara na emulsifiers dị elu na-eme ka iwu ụlọ dị mfe.Ọ dịghị mkpa ikpo ọkụ asphalt na elu okpomọkụ nke 170 ~ 180 Celsius C tupu eji.Ihe ndị na-emepụta ihe ndị dị ka ájá na gravel adịghị mkpa ka akpọnwụ ma kpoo ọkụ, nke nwere ike ịchekwa ọtụtụ mmanụ ọkụ na ike ọkụ..N'ihi na emulsion asphalt nwere ezigbo ọrụ, enwere ike kesaa ya n'elu nchikota ma nwee ezigbo adhesion na ya, n'ihi ya, ọ nwere ike ịchekwa ọnụ ọgụgụ nke asphalt, mee ka usoro ihe owuwu dị mfe, meziwanye ọnọdụ ihe owuwu, ma belata mmetọ na gburugburu ya. gburugburu ebe obibi.N'ihi uru ndị a, emulsified asphalt bụ ọ bụghị naanị adabara ighe okporo ụzọ, kamakwa maka mkpọda nchebe nke jupụtara embankments, waterproofing nke ụlọ elu ụlọ na abaitiat, elu anticorrosion nke metal ihe, ugbo ala mma na osisi ahụ ike, n'ozuzu track bed nke ụgbọ okporo ígwè. Idozi ájá ájá ọzara, wdg. A na-eji ya eme ihe n'ọtụtụ ọrụ.N'ihi na emulsified asphalt nwere ike ọ bụghị naanị melite ewu technology nke na-ekpo ọkụ asphalt, kamakwa ịgbasa ngwa akporo nke asphalt, emulsified asphalt emewo ngwa ngwa.

Asphalt emulsifier bụ ụdị surfactant.Ọdịdị kemịkalụ ya nwere otu lipophilic na hydrophilic.Ọ nwere ike adsorbed na interface n'etiti asphalt ahụ na mmiri, si otú budata mbenata free ike nke interface n'etiti asphalt na mmiri, na-eme ka ọ a surfactant na Nleta a edo na anụ emulsion.

Surfactant bụ ihe nwere ike ibelata elu erughị ala nke mmiri mgbe agbakwunyere na obere ego, ma nwee ike gbanwee njirimara interface na ọnọdụ nke usoro ahụ, si otú a na-emepụta wetting, emulsification, ụfụfụ, ịsacha, na mgbasa., antistatic, lubrication, solubilization na usoro ọrụ iji mezuo ihe achọrọ nke ngwa bara uru.

N'agbanyeghị ụdị surfactant ọ bụla, molecule ya na-abụkarị akụkụ na-abụghị polar, hydrophobic na lipophilic hydrocarbon chain na polar, oleophobic na hydrophilic group.Akụkụ abụọ a na-adịkarị n'elu.Ngwunye abụọ nke molekul onye na-arụ ọrụ na-etolite nhazi asymmetric.Ya mere, usoro ihe omimi nke surfactant bụ ihe e ji mara molekul amphiphilic nke bụ ma lipophilic na hydrophilic, ma nwee ọrụ nke ijikọ mmanụ na mmiri mmiri.

Mgbe surfactants gafere ụfọdụ ntinye na mmiri (mkpụrụ ndụ micele dị oke mkpa), ha nwere ike ịmalite micelles site na mmetụta hydrophobic.Usoro emulsifier kacha mma maka emulsified asphalt dị ukwuu karịa itinye uche micelle dị oke egwu.
