Njengoba imishini yokuxuba itiyela esetshenzisiwe yathengwa kusenesikhathi, uhlelo lwayo lokuvutha kanye nokomisa lungahlangabezana nezidingo zokushiswa kukadizili. Kodwa-ke, njengoba intengo kadizili ikhuphuka, ukusebenza kahle kwezomnotho kokusebenzisa imishini kuba phansi futhi phansi. Mayelana nalokhu, abasebenzisi bathemba ukuthi ingaxazululwa ngokushintsha uhlelo lokusha lwemishini yokuxuba i-asphalt. Yiziphi izixazululo ezinengqondo ochwepheshe abanazo kulokhu?
Ukuguqulwa kwesistimu yokushiswa kwemishini yokuxuba i-asphalt ikakhulukazi ihlanganisa izici ezilandelayo. Eyokuqala iwukushintshwa kwedivayisi evuthayo, esikhundleni sesibhamu sokuqala sikadizili esivuthayo ngesibhamu sesifutho esinezinjongo ezimbili zikadizili. Le divayisi imfushane futhi ayidingi ukusongwa kwezintambo zikagesi zokushisisa. Okubalulekile ukuthi ngeke ivinjwe amafutha asindayo asele, okuvumela amafutha anzima ukuba ashiswe ngokugcwele futhi anciphise ukusetshenziswa kwamafutha anzima.
Isinyathelo sesibili ukuguqula ithangi likadizili langaphambili bese ubeka ikhoyili yamafutha ashisayo ngaphansi kwethangi ukuze isetshenziselwe ukushisisa uwoyela asindayo ufike ezingeni lokushisa elidingekayo. Ngesikhathi esifanayo, iKhabhinethi ehlukile yokulawula ugesi kufanele imiswe ukuze lonke uhlelo lubone ukushintsha okuzenzakalelayo phakathi kwedizili namafutha asindayo, nokuvikela uhlelo ngama-alamu azwakalayo nabonakalayo.
Enye ingxenye ukuthuthukiswa kwesithando somlilo samafutha ashisayo, ngoba esokuqala kwakuyisithando somlilo samafutha ashisayo esishisa udizili, futhi kulokhu sathathelwa indawo isithando somlilo esishisayo esibaswa ngamalahle, esingasindisa kakhulu izindleko.
