Emulsified asphalt o se suau'u-i-vai sua gaosia e alafala ma vai faatasi ai ma surfactant faaopoopo e ala i emulsified meafaigaluega gaosiga emulsified. E sua ile vevela ole potu ma e mafai ona fa'aoga sa'o pe fa'afefe ile vai. E malo le asphalt ile vevela ole potu. Afai e manaʻomia le faʻaaogaina, e manaʻomia le faʻamafanafanaina i le vai aʻo leʻi faʻaaogaina. O le maualuga o le vevela e sili atu ona lamatia le faʻaaogaina. Emulsified asphalt o se mea e maua mai le asphalt. Pe a faʻatusatusa i le asphalt, e iai le lelei o le fausiaina faigofie, faʻaleleia le siosiomaga o le fausiaina, leai se manaʻoga mo le faʻamafanafanaina, saogalemu ma le puipuiga o le siosiomaga.
Fa'avasegaina o le emulsified asphalt:

1. Fa'avasega ile faiga fa'aoga
Emulsified asphalt e faʻavasegaina e tusa ai ma le auala o le faʻaogaina, ma o lona faʻaaogaina e mafai foi ona faʻamatalaina i le auala e faʻaoga ai. E masani ona fa'aogaina le fa'asala fa'aluulu fa'asu'u e pei o le fa'asusu vai, fa'amau fa'apipi'i, fa'amau fa'amau, suau'u fa'amaufa'ailoga, fa'apalapala fa'apipi'i emulsified, ma fa'apipi'i fa'apipi'i emulsified tekonolosi togafitiga luga. E mana'omia le fa'afefiloi o le asphalt fa'afefiloi ma ma'a. A maeʻa le faʻafefiloi, e mafai ona faʻasalalau faʻasalalau seia oʻo ina faʻamalo le emulsified asphalt ma faʻafefe ai le vai ma le matagi, ona mafai lea ona faʻaaogaina mo feoaiga masani. Fa'afefiloi emulsified asphalt e mafai ona fa'aaogaina e avea o se mea e le susu po'o se fa'amau i luga o le fausiaina o inisinia. E masani ona faʻaaogaina i le faʻamaufaʻailogaina o le slurry, faʻafefiloi faʻafefiloi emulsified asphalt luga tekinolosi togafitiga, emulsified asphalt iliili fefiloi sima, emulsified asphalt sima sima, toe faaleleia o pavement potholes ma isi faʻamaʻi, malulu toe faʻaaogaina o mea tuai asphalt pavement mea ma isi faiga faafefiloi faufale.
2. Fa'avasegaina e tusa ai ma le natura fa'atosina o mea fa'apipi'i emulsifiers
Emulsified asphalt ua fa'avasegaina e tusa ai ma le natura vaega ma e mafai ona vaevaeina i: cationic emulsified asphalt, anionic emulsified asphalt, ma nonionic emulsified asphalt. I le taimi nei, o le cationic emulsified asphalt o loʻo faʻaaogaina lautele.
Cationic emulsified asphalt ei ai uiga o le pipii lelei ma e masani ona faʻaaogaina i le fausiaina o le susu ma le fausiaina o le alatele. Cationic emulsified asphalt ua vaevaeina i ni ituaiga se tolu e tusa ai ma le saoasaoa demulsification: ta'e vave ituaiga, ituaiga ta'e feololo, ma ta'e lemu ituaiga. Mo fa'amatalaga fa'apitoa, fa'amolemole va'ai i le fa'aofiina o fa'amea fa'ameamea ma emulsifiers fa'alelei i Mea Faufale. E mafai ona vaevaeina ituaiga ta'e lemu i ni ituaiga se lua e tusa ai ma le taimi fa'afefiloi o le fa'afefiloi: fa'atulagaina lemu ma le fa'atulagaina vave.
Anionic emulsified asphalt ua vaevaeina i ni ituaiga se lua: ta'ei feololo ma ta'e lemu. O le saosaoa demulsification o le paluga o le seti lemu.
E leai se ionic emulsified asphalt e leai se taimi manino demulsification ma e masani ona faʻaaogaina mo le sima ma faʻafefiloi faʻapipiʻi ma faʻapipiʻiina kosi faavae mautu semi-malosi ma mo semi-malosi lapisi suauʻu lapisi.
E fa'afefea ona filifili po'o fea le emulsified asphalt e fa'aoga i se talosaga? E mafai ona e vaʻai i lenei tusiga, pe faʻafesoʻotaʻi le 'auʻaunaga a tagata faʻatau! Faafetai mo lou gauai ma le lagolago!
