Imishini yokuhlanganisa i-asphalt izodala ukungcola okuningi kothuli ngesikhathi sokusetshenziswa. Ukunciphisa inani lothuli olukhiqizwayo, singaqala ngokuthuthukisa imishini yokuxuba i-asphalt. Ngokwenza ngcono ukwakheka kwawo wonke umshini, singakwazi ukwandisa ukunemba komklamo wengxenye ngayinye yokuvala yomshini, futhi sizame ukwenza okokusebenza kuvalwe ngokugcwele ngesikhathi senqubo yokuxuba, ukuze uthuli lulawuleke emishinini yokuxuba. Ngaphezu kwalokho, kuyadingeka ukunaka imininingwane yokuthuthukisa ukusebenza kwemishini futhi unake ukulawulwa kokuchichima kothuli kuzo zonke izixhumanisi.
Ukukhipha uthuli komoya kungenye yezindlela zokulawula uthuli emishinini yezitshalo exuba itiyela. Le ndlela iyindlela yakudala. Isebenzisa kakhulu iziqoqi zothuli lwe-cyclone ukususa uthuli. Kodwa-ke, njengoba lesi siqoqi sothuli esidala singasusa izinhlayiya ezinkulu zothuli kuphela, asikwazi ukuhlangabezana ngokugcwele nokwelashwa kothuli. Kodwa-ke, umphakathi uphinde wenza intuthuko eqhubekayo kubaqoqi bethuli lomoya. Ngokuhlanganisa amasethi amaningi abaqoqi bothuli be-cyclone osayizi abahlukahlukene, ukwelashwa kothuli lwezinhlayiya ezinosayizi abahlukahlukene kungaqedwa.
Ngaphezu kwalezi zindlela ezimbili ezingenhla zokulawula uthuli, imishini yezitshalo yokuxuba itiyela ingase futhi isebenzise izindlela zokususa uthuli olumanzi kanye nezindlela zokususa uthuli lwezikhwama. Ukukhipha uthuli olumanzi kunezinga eliphezulu lokwelapha uthuli futhi kungasusa uthuli olukhiqizwa ngesikhathi sokuxutshwa, kodwa ngenxa yokuthi amanzi asetshenziswa njengempahla eluhlaza yokukhipha uthuli, kuzodala ukungcoliswa kwamanzi. Ukukhipha uthuli lwesikhwama kuyindlela efanelekile yokususa uthuli yemishini yokuxuba itiyela. Kuyimodi yokususa uthuli yohlobo lwenduku elungele ukwelashwa kwezinhlayiya zothuli ezincane.
