Njengomvelisi wezityalo zebhitumene ezilungisiweyo, siye sabandakanyeka kwimveliso kunye nokubonelela ngezixhobo zebhitumene ezilungisiweyo kunye nezinye iimveliso ezinxulumene nazo iminyaka emininzi. Siyazi ukuba nokuba yeyiphi na imveliso esetyenziswayo, kufuneka sibe nokuqonda okupheleleyo kwesityalo sebhitumene esilungisiweyo, kuyafana nokuba nobuchule bezixhobo zebhitumene ezilungisiweyo. Apha, ukuze kukhuthazwe ngakumbi ukukwazi kwabathengi kuyo, amagcisa abelana: Zeziphi izakhono zogcino lwesityalo sebhitumene esilungisiweyo?
1. Izityalo zebhitumene ezilungisiweyo, iimpompo zokudlulisa, iimotor, kunye nezinciphisi kufuneka zigcinwe ngokuhambelana neemfuno zencwadana yemiyalelo. Iimpawu zetanki yokufudumeza i-bitumen zezi: ukufudumeza ngokukhawuleza, ukukhuselwa kwendalo kunye nokugcinwa kwamandla, umthamo omkhulu wokuvelisa, akukho kusetyenziswa kangangoko usebenzisa, akukho ukuguga, kunye nokusebenza okulula. Zonke izincedisi zikwitanki yokugcina, ekulungele kakhulu ukuhamba, ukuphakanyiswa, kunye nokugcinwa. Kulula kakhulu ukuhambahamba. Le mveliso ayifudumezi ibhitumene eshushu kwi-160 degrees ngaphezu kwemizuzu engama-30.
2. Uthuli olukwibhokisi yolawulo kufuneka lususwe kanye kwiinyanga ezintandathu. Ungasebenzisa i-blower blower ukususa uthuli ukukhusela uthuli ekungeneni kumatshini kunye neendawo eziwonakalisayo. Isixhobo sebhitumene esilungisiweyo sizalisa iintsilelo zezixhobo zokufudumeza i-oyile ye-oyile ephezulu kunye nexesha elide lokufudumeza kunye nokusetyenziswa kwamandla aphezulu. I-heater inxalenye efakwe kwitanki ye-bitumen ifanelekile ukugcinwa kwe-bitumen kunye nokufudumeza kwizithuthi kunye neenkqubo zikamasipala.
3. Ibhotolo engaxutywanga kufuneka igalelwe kube kanye kwiitoni ezili-100 zebhitumene ekhutshiweyo eveliswa ngumatshini womgubo wemicron.
4. Emva kokusebenzisa isixhobo sokuxuba ibhitumene elungisiweyo, umlinganiselo we-oyile kufuneka ujongwe rhoqo.
5. Ukuba isixhobo sebhitumene esilungisiweyo sipakwe ixesha elide, ulwelo olukwitanki kunye nombhobho kufuneka lukhutshwe, kwaye inxalenye nganye eshukumayo mayizaliswe ngegrisi.
