Kukho izilumkiso ezininzi zokusebenza kwezixhobo zokuxuba i-asphalt ezincinci kunye neziphakathi kwizityalo zokuxuba i-asphalt. Masijonge ngakumbi:

1. Izixhobo ezincinci zokuxuba i-asphalt kufuneka zibekwe kwindawo eflethi kunye neyunifomu, kwaye umsebenzisi kufuneka alungise amavili ezixhobo zokuthintela umatshini ukuba udibanise ngexesha lokusebenza.
2. Khangela ukuba i-clutch ye-drive kunye ne-brake inovakalelo kwaye inokwethenjelwa ngokwaneleyo, kwaye ingaba zonke iindawo ezidibanisayo zezixhobo zigugile. Ukuba kukho nayiphi na into engaqhelekanga, umsebenzisi kufuneka ayilungise ngokukhawuleza.
3. Isalathiso sokujikeleza kwegubu kufuneka sihambelane nesalathiso sotolo. Ukuba akunjalo, umsebenzisi kufuneka alungise iingcingo zomatshini.
4. Emva kokuba umsebenzi ugqityiwe, umsebenzisi kufuneka akhuphe umbane kwaye atshixe ibhokisi yokutshintsha ukukhusela abanye ukuba basebenze ngokungafanelekanga.
5. Emva kokuqala umatshini, umsebenzisi kufuneka ajonge ukuba iinxalenye ezijikelezayo zisebenza ngokufanelekileyo. Ukuba akunjalo, umsebenzisi kufuneka amise umatshini ngokukhawuleza kwaye ahlolisise ngenyameko, kwaye uqale ukusebenza emva kokuba yonke into ibuyele kwisiqhelo.
