Xa kuthengwa isityalo sokuxuba i-asphalt, abasebenzi bezobugcisa bomenzi benza izikhumbuzo ezibalulekileyo malunga neemfuno zokuthambisa izixhobo, kubandakanywa ukuthambisa kwecandelo ngalinye, elingenako ukuhoywa. Ngokubhekiselele koku, abasebenzisi baye baqulunqa imigangatho engqongqo ukuyilawula, ngolu hlobo lulandelayo:
Okokuqala, ioli efanelekileyo yokuthambisa kufuneka yongezwe rhoqo kwicandelo ngalinye kwizityalo zokuxuba i-asphalt; ngokobungakanani beoli yokuthambisa, kufuneka igcinwe igcwele. Uluhlu lweoli kwi-oyile ye-oyile kufuneka lufikelele kwinqanaba lamanzi elichazwe ngumgangatho, kwaye akufanele libe lininzi okanye lincinci. Ngaphandle koko, kuya kuchaphazela ukusebenza kwamalungu; ngokubhekiselele kwikhwalithi yeoli, kufuneka ihlambuluke kwaye ingaxutywa kunye nokungcola okunjengokungcola, uthuli, iitshiphusi, kunye nomswakama ukuze ugweme umonakalo kwiindawo zesikhululo sokuxuba i-asphalt ngenxa yokungahambi kakuhle.
Okwesibini, i-oyile yokuthambisa kwitanki kufuneka itshintshwe rhoqo, kwaye itanki kufuneka icocwe ngaphambi kokutshintshwa ukuze kuthintelwe ukungcoliseka kweoli entsha. Ukuze ungachatshazelwa zizinto zangaphandle, izikhongozeli ezifana neetanki zamafutha kufuneka zitywinwe kakuhle ukuze ukungcola kungangeni.
