Kwinkqubo yokuxuba i-asphalt, ukufudumeza yenye yezinto eziyimfuneko, ngoko ke isityalo sokuxuba i-asphalt kufuneka sixhotyiswe ngenkqubo yokufudumala. Le nkqubo inokusebenza kakubi phantsi kwefuthe lezinto ezahlukeneyo, oku kuthetha ukuba inkqubo yokufudumala kufuneka iguqulwe.
Sifumene ukuba xa isityalo se-asphalt sisebenza kumaqondo okushisa aphantsi, ipompo yokujikeleza i-asphalt kunye nepompo yokutshiza ayinakusebenza, ibangela ukuba i-asphalt kwisikali se-asphalt iqiniswe, ekugqibeleni ibangele ukuba izityalo zokuxuba i-asphalt zingakwazi ukuvelisa ngokuqhelekileyo. Emva kokuhlolwa, kwaqinisekiswa ukuba i-asphalt kumbhobho yaqina ngenxa yokuba ubushushu bombhobho wokuthutha i-asphalt awuzange uhlangabezane neemfuno.

Izizathu ezithile kukuba kukho izinto ezine ezinokwenzeka. Enye kukuba itanki ye-oyile yezinga eliphezulu le-oyile yokudlulisa ukushisa iphantsi kakhulu, okubangela ukungahambi kakuhle kweoli yokudlulisa ukushisa; enye kukuba ityhubhu yangaphakathi yetyhubhu ephindwe kabini i-eccentric; enye yeyokuba umbhobho we-oyile wokudluliselwa kobushushu mde kakhulu; okanye Kungenxa yokuba imibhobho yeoli ye-thermal ayizange ithathe amanyathelo asebenzayo e-insulation, njl., ekugqibeleni ichaphazela umphumo wokufudumala.
Ngokusekelwe kuhlalutyo olungentla kunye nesiphelo, inkqubo yokufudumeza ioli ye-thermal yesityalo sokuxuba i-asphalt kufuneka iguqulwe. Amanyathelo athile abandakanya ukuphakamisa indawo yetanki yokuzalisa ioli; ukufaka ivalve yokukhupha; ukucheba umbhobho wokuhambisa; kunye nokufakela impompo yokukhuthaza kunye nomaleko wokugquma. Emva kokuphuculwa, ubushushu bezityalo zokuxuba i-asphalt zifikelele kwinqanaba elifunekayo kwaye zonke izinto zisebenza ngokuqhelekileyo.
