Imishini yokuhlanganisa i-asphalt ihlangabezana nezinkinga ezihlukene, futhi izindlela zokuzisingatha nokuyixazulula nazo zihlukile. Isibonelo, enye yezinkinga ezivamile zemishini yokuxuba i-asphalt ukuthi izingxenye zikhathele futhi zilimale. Ngalesi sikhathi, indlela abakhiqizi okudingeka bayenze ukuqala ekukhiqizeni izingxenye.

Abakhiqizi bemishini yezitshalo ezixuba i-asphalt bangathuthuka ngokuthuthukisa isiphetho sezingxenye ezingaphezulu, noma ngokwamukela ukuhlunga okuphakathi nendawo okusesilinganisweni ukuze kuzuzwe inhloso yokunciphisa ukugxilwa kwengcindezi kwezingxenye. I-Carburizing kanye nokucisha kungasetshenziswa futhi ukuthuthukisa ukusebenza kwemishini yokuxuba i-asphalt. Lezi zindlela zinganciphisa umphumela wokukhathala nokulimala kwezingxenye.
Ngaphezu kokukhathala nokulimala kwezingxenye, izitshalo zokuxuba i-asphalt nazo zizobhekana nesimo sokulimala kwezingxenye okubangelwa ukungqubuzana. Ngalesi sikhathi, abakhiqizi kufanele bazame ukusebenzisa izinto ezingagugi, futhi ngesikhathi esifanayo, kufanele bazame ukunciphisa amathuba okungqubuzana lapho beklama ukuma kwezingxenye zemishini yokuxuba i-asphalt. Uma okokusebenza kuhlangabezana nomonakalo wezingxenye obangelwe ukugqwala, abasebenzisi bangasebenzisa izinto ezimelana nokugqwala njenge-chromium ne-zinc ukuze bacwebezele ubuso bezingxenye zensimbi. Le ndlela ingavimbela ukugqwala kwezingxenye.
