Isitshalo sokuxuba i-asphalt singenye yemishini ebaluleke kakhulu yokukhiqiza imikhiqizo ye-asphalt. Uma ihluleka, umphumela womkhiqizo uzoncishiswa nakanjani. Lona umthwalo okufanele uqashelwe, ngakho yiziphi izinkinga ezivame ukwenzeka ezitshalweni zokuxuba i-asphalt?
Okuvame kakhulu imikhiqizo engazinzile kanye nokusebenza kahle kokukhiqiza kwemishini. Ngemva kokuhlaziya, siyazi ukuthi izizathu eziyinhloko zokwehluleka okunjalo yilezi ezilandelayo:

1. Isilinganiso sokuxuba esingalungile sezinto zokusetshenziswa;
2. Izinga lempahla eluhlaza alikho ezingeni;
3. Inani lokushiswa kukaphethiloli emshinini liphansi;
4. Imingcele yokusebenza kwemishini isethwe ngendlela engafanele.
Uma ususitholile isizathu, ungathatha izinyathelo ezihambisanayo.
Ngaphandle kokusebenza kahle okuphansi, izinga lokushisa lokukhishwa kwezitshalo zokuxuba i-asphalt ngezinye izikhathi alizinzile futhi alikwazi ukuhlangabezana nezidingo eziqinile zokushisa. Isizathu sale nkinga ukulawula izinga lokushisa lokushisa okungalungile, futhi ubukhulu belangabi lokushisa budinga ukulungiswa ukuze kuthuthukiswe lesi simo.
