Imishini yokuxuba i-asphalt idlala indima ebaluleke kakhulu embonini yokwakhiwa kwemigwaqo. Imishini izokhiqiza igesi engcolile, uthuli nezinye izingozi zomphakathi ngesikhathi sokukhiqiza. Ukuze kuqinisekiswe ukuthi imvelo ayithinteki, abakhiqizi kudingeka bathathe izinyathelo ezifanele zokulawula lezi zingozi. Ingxenye elandelayo yalesi sihloko imayelana ne-asphalt Isingeniso esifushane sezindlela zokulawula izingozi zothuli ezitshalweni ze-asphalt zinikezwa.

Ngesikhathi sokusetshenziswa kwemishini yokuxuba i-asphalt, kuzokwenziwa inani elikhulu lokungcoliswa kothuli. Ukuze kuncishiswe inani lokukhiqiza uthuli, singaqala ngokuthuthukisa isitshalo sokuxuba i-asphalt. Ngokuthuthuka komklamo wonke womshini, singakwazi ukwandisa ukunemba komklamo wengxenye ngayinye yokuvala yomshini futhi sikwenze kube nokwenzeka ngangokunokwenzeka. Imishini ivalwe ngokugcwele ngesikhathi senqubo yokuxuba, ukuze uthuli lukwazi ukulawulwa ngaphakathi kwemishini yokuxuba. Ngaphezu kwalokho, kuyadingeka ukunaka imininingwane yokuthuthukisa ukusebenza ngaphakathi kwemishini futhi unake ukulawulwa kokuchitheka kothuli kuzo zonke izixhumanisi.

Ukukhipha uthuli komoya kungenye yezindlela zokulawula izingozi zothuli emishinini yokuxuba itiyela. Le ndlela iyindlela yakudala, esebenzisa kakhulu uthuli lwe-cyclone ukwenza imisebenzi yokususa uthuli. Kodwa-ke, lo mqoqi wothuli wakudala angasusa uthuli oluncane uma kuqhathaniswa. Izinhlayiya ezinkulu zothuli, ngakho-ke azikwazi ukuhlangabezana ngokugcwele nezimfuneko zokucubungula uthuli. Kodwa manje umphakathi uphinde wenza intuthuko eqhubekayo kubaqoqi bothuli lomoya. Amasethi amaningi abaqoqi bothuli be-cyclone amasayizi ahlukene asetshenziswa ngokuhlanganiswa ukuqedela ukwelashwa kothuli lwezinhlayiya ezinosayizi abahlukahlukene.

Ngaphezu kwalezi zindlela ezimbili ezingenhla zokulawula uthuli, izitshalo zokuxuba itiyela zingasebenzisa nokukhipha uthuli olumanzi kanye nokususwa kothuli lwezikhwama. Ukukhipha uthuli olumanzi kunezinga eliphezulu lokwelapha uthuli futhi kungasusa uthuli oluvela ngesikhathi sokuxutshwa. Kodwa-ke, ngenxa yokuthi amanzi asetshenziswa njengezinto ezingavuthiwe zokususa uthuli, azodala ukungcoliswa kwamanzi. Ukususwa kothuli lwesikhwama kuyindlela efanelekile yokususa uthuli esitshalweni sokuxuba i-asphalt. Kuyimodi yokususa uthuli lwenduku futhi ifanele ukwelashwa kothuli ngezinhlayiya ezincane.
