Emulsified asphalt o se emulsion emulsion lea e tu'u fa'atasi ai ma le vai e ala i le gaioiga a surfactants ma masini e fausia ai se vai i le vevela o le potu ma e mafai ona fa'aoga sa'o e aunoa ma le fa'amafanafanaina. A fa'atusatusa i le asphalt, emulsified asphalt e fa'asaoina le malosi, fa'alelei le si'osi'omaga, ma faigofie ona fa'aoga.
I tausaga talu ai nei, ua faʻaaogaina le emulsified asphalt i le tele o alamanuia. Aemaise lava: alalaupapa ma alavai, fausiaina o auala ma le tausiga, fausiaina o fale, faʻaleleia o le eleele, faʻapipiʻiina o oneone toafa, faʻamautu o le malifa, faʻamaʻi uʻamea, moega o nofoaafi, ma isi.
Ole galuega autu ole emulsified asphalt i alalaupapa alalaupapa ole waterproofing. E lua auala e faʻaoga ai: faʻafefe ma pulumu, lea e mafai ona e filifilia e tusa ai ma le tulaga faʻapitoa.
I le fausiaina ma le tausiga o auala. I pavements fou, emulsified asphalt o loʻo faʻaaogaina i le paʻu paʻu, apa faʻapipiʻi, faʻamaufaʻailoga slurry ma faʻamaufaʻailoga iliili faʻatasi e le susu. I le tulaga o le tausiga puipuia, emulsified asphalt e faʻaaogaina i faʻamaufaʻailoga slurry, micro surfacing, faʻalelei lelei, faʻamaufaʻailoga pulou, ma isi.
I le tulaga o le fausiaina o fale e le susu, faʻafefe ma vali o auala autu foi ia.
