Xa urhulumente we-Asphalt ezenzekelayo usebenzisa i-valtorch ehleliweyo yokutshisa ityhubhu ye-Asphalt Tak, i-chimney kwitanki ye-Asphalt kufuneka ivulwe kuphela emva kokuba i-asphalt ye-asphalt ibeka ityhubhu ye-asphalt. Xa idangatye le-herchch likhulu kakhulu okanye lisasazeka, i-ratio speatch kufuneka itshintshwe kuqala, kwaye ipetroli egqithisileyo kufuneka itshiswe ngaphambi kokusetyenziswa.

Ngaphambi kokusebenzisa i-sperchch yesisasazo se-Asphalt esenzekelayo, umbhobho we-oyile kunye nezibuko elikufuphi nezona zikufutshane zivaliwe kuqala. Emva kokuba i-valtorch ephathekayo ikhutshiwe, akufuneki ukuba isondele kwizixhobo ezinokutsha. I-assorminal ye-asphalt ezenzekelayo kufuneka iqhutywa ngesantya esiphakathi xa ilayishwe ngokupheleleyo nge-asphalt. Ukuba kukho ijikajika okanye ezantsi, kufuneka ilahlekelwe kwangaphambili, kwaye ukutsiba okungxamisekileyo kufanele kuthintelwe kangangoko kunokwenzeka. Inkqubo yokufudumeza ayivumelekanga ngexesha lokuqhuba.
