1. Ta'avale fa'asalalau masani
E mafai ona faʻaaogaina mo le fausiaina o faʻamaufaʻailoga pito i luga ma lalo, faʻamaufaʻailoga faʻafefe, faʻamaʻi luga o le ala, faʻapipiʻi ala laupapa, faʻamaufaʻailoga puao ma isi galuega i luga o le auala. E mafai foi ona faʻaaogaina mo le felauaiga o le asphalt vai poʻo isi suauu mamafa.

2. Ta'avale fa'asalalau fa'asala fa'atotonu atoatoa
E maualuga le fa'agaioiina o ta'avale fa'apipi'i otometi ona o le pulea o masini komepiuta. O lo'o fa'aaogaina lautele i le fausiaina o auala tetele ma galuega fa'aleleia o auala tetele. E mafai ona faʻaogaina mo le pito i luga ma lalo o faʻamaufaʻailoga faʻamau, faʻamaufaʻailoga faʻapipiʻi, papa e le susu, faʻapipiʻi faʻapipiʻi, ma isi. E mafai ona faʻaaogaina mo le fausiaina o le faʻafefeteina o luga o le eleele, faʻapipiʻiina o le ala laupapa, faʻamau faʻamaufaʻailoga puao ma isi galuega faatino, ma e mafai foi ona faʻaaogaina mo le felauaiga o le asphalt vai poʻo isi suauu mamafa.

E faigofie ona fa'agaioi le ta'avale fa'apipi'i pa'u pa'u. I luga o le faʻavaeina o le faʻaaogaina o tekinolosi eseese o oloa tutusa i totonu o le fale ma fafo, e faʻaopoopoina mea faʻapitoa e faʻamautinoa ai le lelei o le fausiaina ma le mamanu faʻaletagata e faʻamaonia ai le faʻaleleia o tulaga faufale ma le siosiomaga faufale. O lona mamanu talafeagai ma le faʻatuatuaina e faʻamautinoa ai le tutusa o le faʻasalalauina o le asphalt, o le faʻatautaia o komepiuta faʻapisinisi e mautu ma faʻatuatuaina, ma o le faʻatinoga faʻapitoa o le masini atoa ua oʻo i le tulaga maualuga o le lalolagi. O lenei taavale o loʻo faʻaauau pea ona faʻaleleia, faʻafouina ma faʻaatoatoaina e le matagaluega faʻainisinia a le matou kamupani i le taimi o le fausiaina, ma o loʻo i ai le gafatia e talafeagai mo siosiomaga faigaluega eseese.

O lenei oloa e mafai ona suitulaga i le loli o lo'o i ai nei. I le taimi o le fausiaina, e le gata e mafai ona faʻasalalau le paʻu paʻu, ae faʻapea foʻi le emulsified asphalt, diluted asphalt, vevela vevela, mamafa feʻaveaʻi asphalt ma maualuga-viscosity suia asphalt.
