Njengomkhiqizi wezitshalo zebitumen eziguquliwe, sesineminyaka eminingi sisebenza ekukhiqizeni nasekuhlinzekeni imishini yebitumen eguquliwe kanye neminye imikhiqizo ehlobene nayo. Siyazi ukuthi kungakhathaliseki ukuthi yimuphi umkhiqizo osetshenziswayo, kufanele sibe nokuqonda okuphelele kwesitshalo sebitumen esilungisiwe, kuyafana nangokusebenzisa kahle izinto zokusebenza zebitumen eziguquliwe. Lapha, ukuze kuqhutshekwe kuthuthukiswe ukukwazi kwamakhasimende kuso, ochwepheshe babelana: Yimaphi amakhono okunakekela isitshalo sebitumen esilungisiwe?
1. Izitshalo zebitumen ezilungisiwe, amaphampu okudlulisa, izinjini, nezinciphisi kufanele zigcinwe ngokuhambisana nezidingo zemanuwali yemiyalelo. Izici zethangi lokushisisa itiyela yilezi: ukushisisa okusheshayo, ukuvikelwa kwemvelo nokonga amandla, umthamo omkhulu wokukhiqiza, akukho ukusetshenziswa ngendlela oyisebenzisa ngayo, akukho ukuguga, nokusebenza okulula. Zonke izesekeli zisethangini lokugcina, elilungele kakhulu ukunyakaza, ukuphakanyiswa, nokugcinwa. Kulula kakhulu ukuhambahamba. Lo mkhiqizo ngokuvamile awushisi itiyela elishisayo ku-160 degrees ngaphezu kwemizuzu engu-30.
2. Uthuli olusebhokisini lokulawula kufanele lukhishwe kanye njalo ezinyangeni eziyisithupha. Ungasebenzisa i-dust blower ukuze ususe uthuli ukuvimbela uthuli ukuthi lungangeni emshinini kanye nezingxenye ezilimazayo. Imishini yebitumen eguquliwe igcwalisa ukushiyeka kwemishini yokushisa uwoyela oshisayo esezingeni eliphezulu enesikhathi eside sokushisa kanye nokusetshenziswa kwamandla okuphezulu. I-heater eyingxenye efakwe ku-bitumen tank ifaneleka ukugcina i-bitumen nokushisa ekuthuthweni nasezinhlelweni zikamasipala.
3. Ibhotela elingafakwanga usawoti kufanele lifakwe kanye kuwo wonke amathani ayi-100 etiyela elikhihliziwe elikhiqizwe umshini we-micron powder.
4. Ngemva kokusebenzisa idivayisi yokuxuba itiyela eguquliwe, igeji yezinga likawoyela kufanele ihlolwe njalo.
5. Uma impahla yetiyela eguquliwe ipakwe isikhathi eside, uketshezi olusethangini nasemapayipini kufanele kukhishwe, futhi ingxenye ngayinye ehambayo kufanele igcwaliswe ngamafutha.
