Ngesikhathi sokwakhiwa komgwaqo, izixube ze-asphalt kufanele zisetshenziswe, futhi wonke umuntu kufanele akwazi lokhu. Ngaphandle kwekhwalithi jikelele yomshini, ukukhethwa nokusetshenziswa kwezingxenye nakho kudlala indima ebalulekile, okuzothinta izinga lokwakha kanye nezindleko zokukhiqiza. Thatha isikrini kumxube we-asphalt njengesibonelo ukuze uthole incazelo enemininingwane.

Kungakhathaliseki ukuthi hlobo luni lwe-mixer enengqondo, uma ikhwalithi yensimbi ye-mesh yesikrini esidlidlizayo, usayizi ozwakalayo we-mesh nezimbobo ze-mesh, kanye nokunemba kokufakwa kwe-mesh kungathathwa ngokungathi sína, umphumela wokuxuba ngeke ube okahle kuqala. Lokhu kuphinde kuthinte ukusetshenziswa kwe-asphalt. Ngakho-ke, ukukhethwa kwezikrini ezisezingeni eliphezulu neziphezulu ezigqokekayo kuyisimo esiyisisekelo sokuxuba i-asphalt enesivuno esiphezulu nekhwalithi ephezulu, futhi kunganciphisa izindleko.
Ezinye izinkampani ezikhiqiza umshini wokuxuba i-asphalt zisebenzisa izikrini eziphansi ezenziwe ngensimbi evamile eshibhile futhi azinaki izidingo zokulukwa kwezintambo zensimbi ezikhethekile ezingagugi kanye nezinqubo zokuhlela eziyinkimbinkimbi, okuholela ekuphileni okufushane kwesevisi futhi kuthinte kabi ukusebenza okuvamile kweyunithi.
