Enqubweni yesitshalo sokuxuba i-asphalt, ukushisa kungenye yezixhumanisi ezibalulekile, ngakho-ke uhlelo lokushisa kufanele lumiswe esiteshini sokuxuba i-asphalt. Lolu hlelo luzohluleka ngaphansi kwethonya lezici ezihlukahlukene, okusho ukuthi uhlelo lokushisa kufanele luguqulwe.

Sithole ukuthi lapho isitshalo sokuxuba i-asphalt sisebenza ngaphansi kwezinga lokushisa eliphansi, ipompo yokujikeleza kwe-asphalt kanye nepompo ye-spray ayikwazi ukusebenza, okwenza i-asphalt esikalini se-asphalt iqine, okuholela ekutheni isiteshi sokuxuba i-asphalt singakwazi ukukhiqiza ngokujwayelekile. Ngemva kokuhlolwa, kwafakazelwa ukuthi izinga lokushisa lepayipi elihambisa itiyela alihlangabezani nezidingo, okubangele ukuthi itiyela elisepayipini liqine.
Kunezizathu ezine ezingaba yizizathu ezithile. Enye iwukuthi ithangi lamafutha lezinga eliphezulu lamafutha okudlulisa ukushisa liphansi kakhulu, okuholela ekusakazweni kabi kwamafutha okudlulisa ukushisa; enye iwukuthi ungqimba lwangaphakathi lwepayipi elinezingqimba ezimbili luyi-eccentric; enye ukuthi ipayipi likawoyela odlulisa ukushisa lide kakhulu; noma ipayipi likawoyela elidlulisa ukushisa alizange lithathe izinyathelo ezisebenzayo zokuhlukanisa, njll., ezithinta umphumela wokushisa.
Ngokusekelwe ekuhlaziyweni okungenhla neziphetho, kuyadingeka ukuguqula uhlelo lokushisa amafutha okudlulisa ukushisa esiteshini sokuxuba i-asphalt. Izinyathelo ezithile zihlanganisa ukuphakamisa isikhundla sethangi lokugcwalisa uwoyela; ukufaka i-valve yokukhipha umoya; ukuphungula ipayipi elihambisayo; ukwengeza iphampu ye-booster kanye nongqimba lokufakelwa. Ngemuva kokuthuthukiswa, izinga lokushisa lesitshalo sokuxuba i-asphalt lifinyelele izidingo futhi zonke izingxenye zisebenza ngokujwayelekile.
