Lapho bethenga isiteshi sokuxuba itiyela, ochwepheshe bomkhiqizi benza izikhumbuzo ezibalulekile mayelana nezidingo zokugcotshwa kwezinto zokusebenza, okuhlanganisa ukugcotshwa kwengxenye ngayinye. Mayelana nalokhu, abasebenzisi baphinde bakhe izindinganiso eziqinile zokuyilawula, ngale ndlela elandelayo:
Okokuqala, amafutha okugcoba afanelekile kufanele afakwe njalo engxenyeni ngayinye yesitshalo sokuxuba i-asphalt; ngokwenani lamafutha okugcoba, kufanele agcinwe egcwele, futhi ungqimba lwamafutha echibini lamafutha kufanele lufinyelele izinga lamanzi elichazwe esilinganisweni, hhayi kakhulu noma lincane kakhulu, ngaphandle kwalokho lizothinta ukusebenza kwezingxenye; ngokwezinga likawoyela, kufanele ahlanzeke futhi akumele ahlanganiswe nokungcola okunjengokungcola, uthuli, ama-chips namanzi, ukuze kugwenywe ukulimala ezingxenyeni zesitshalo sokuxuba ngenxa yokungagcobi kahle.
Okwesibili, uwoyela wokugcoba ethangini likawoyela kufanele ushintshwe njalo, futhi ithange likawoyela kufanele lihlanzwe ngaphambi kokushintshwa ukuze kugwenywe ukungcoliswa kwamafutha amasha. Ukuze ugweme ukuthintwa yizinto zangaphandle, iziqukathi ezinjengamathange kawoyela kufanele zigcinwe zivaliwe ukuze ukungcola kungangeni.
