Izitshalo zokuxuba i-asphalt zingenye yemishini ebaluleke kakhulu yokukhiqiza imikhiqizo ye-asphalt. Uma ihluleka, ukukhishwa komkhiqizo kuzokwehla nakanjani. Lona umthwalo osindayo ofanelwe ukunakwa, ngakho yiziphi izinkinga ezivame ukwenzeka ezitshalweni zokuxuba i-asphalt?

Okuvame kakhulu ukungazinzi komkhiqizo kanye nokusebenza kahle kokukhiqiza kwemishini. Ngemuva kokuhlaziywa, kuyaziwa ukuthi izizathu eziyinhloko zalolu hlobo lokwehluleka yilezi ezilandelayo:
1. Ingxenye engafanele yezinto ezingavuthiwe;
2. Izinga eliphansi lezinto zokusetshenziswa;
3. Inani eliphansi lokushiswa kukaphethiloli emishinini;
4. Ukusetha okungalungile kwemingcele yokusebenza kwemishini.
Ngemva kokuthola ukuthi yisiphi isizathu esiyimbangela, thatha izixazululo ezihambisanayo.
Ngaphezu kokusebenza kahle okuphansi, izinga lokushisa lokukhishwa kwesitshalo sokuxuba i-asphalt ngezinye izikhathi alizinzile futhi alikwazi ukuhlangabezana nezidingo eziqinile zokushisa. Imbangela yale nkinga ukulawula izinga lokushisa lokushisa okungalungile, futhi ubukhulu belangabi lokushisa budinga ukulungiswa ukuze kuthuthukiswe lesi simo.
