Izityalo zokuxuba i-asphalt ezikumgangatho ophezulu azikwanelanga nje ukuba zibe nomgangatho ophezulu, kodwa zineenkqubo ezichanekileyo zokusebenza zokuzisebenzisa ngokuchanekileyo. Makhe ndikucacisele iinkqubo zokusebenza zesityalo sokuxuba i-asphalt kuwe.
Zonke iinxalenye zeyunithi yesikhululo sokuxuba i-asphalt kufuneka ziqalwe ngokuthe ngcembe. Emva kokuqala, iimeko zokusebenza zecandelo ngalinye kunye neemeko zokubonisa indawo nganye kufuneka zibe yinto eqhelekileyo, kwaye uxinzelelo lweoli, igesi kunye namanzi kufuneka luhlangabezane neemfuno ngaphambi kokuqala umsebenzi. Ngethuba lenkqubo yokusebenza, abasebenzi banqatshelwe ukungena kwindawo yokugcina kunye naphantsi kwebhakethi yokuphakamisa. Umxubi akufuneki umiswe xa ulayishiwe ngokupheleleyo. Xa kukho impazamo okanye ukuphuma kombane, umbane kufuneka unqunyulwe ngokukhawuleza, ibhokisi yokutshintsha kufuneka itshixiwe, ikhonkrithi ekwidrum yokuxuba kufuneka icocwe, emva koko iphoso lipheliswe okanye umbane ubuyiselwe. Ngaphambi kokuba umxube uvalwe, kufuneka ukhululwe kuqala, kwaye emva koko iitshintshi kunye nemibhobho yecandelo ngalinye kufuneka ivalwe ngokulandelelana. I-samente kwi-tube ye-spiral kufuneka ikhutshwe ngokupheleleyo, kwaye akukho nto kufuneka ishiywe kwi-tube.
