Ngokuthuthuka okuqhubekayo komphakathi, ukuthuthuka okuqhubekayo komnotho nobuchwepheshe, imboni yesimanje yothelawayeka nayo ithuthuka ngokushesha, futhi izidingo zezinto zomgandayo ziya ngokuya ngokuya phezulu. Izinto ezinhle kakhulu zokuhlanganisa itiyela elungisiwe azihlukaniseki ezintweni ezithuthukisiwe zokuhlanganisa itiyela. Imishini yebitumen. Ngakho ngaphandle kwalezi zici, yiziphi ezinye izizathu esingaziqondi? Ake sibheke:

I-1) Eminye imishini yebitumen eguquliwe emakethe ayibhekani nenkinga yebhulokhi ye-SBS ngaphambi kokugaya, ayinakho ukulungiswa okwanele futhi isakhiwo sokugaya asinangqondo. Inqubo yokugaya ayikwazi njalo ukufinyelela ukucoleka okuthile, okuholela ebhitumeni elungisiwe. Ukusebenza kahle kokukhiqizwa kwemikhiqizo yebitumen engenabuthi ayiphezulu futhi nekhwalithi yomkhiqizo ayizinzile. Idinga ukuncika emijikelezweni yokugaya ephindaphindiwe kanye ne-incubation yesikhathi eside ukuxazulula inkinga. Lokhu akukhulisi kakhulu ukusetshenziswa kwamandla kanye nezindleko, kodwa futhi kubangela ikhwalithi yomkhiqizo engazinzile futhi kuthinte isivinini sokwakhiwa kwamaphrojekthi womgwaqo omkhulu.
2) Ngenxa yomzila wenqubo ongenangqondo, ukulahlekelwa kwesigayo kukhulu futhi ikhwalithi yemikhiqizo yebitumen eguquliwe ayizinzile. Ngenxa yokuthi i-SBS evuvukele futhi enyakazisiwe ivame ukwenza izigaxa ezithile noma izinhlayiya ezinkulu, lapho ingena ekamelweni lokugaya, ngenxa yesikhala esilinganiselwe kanye nesikhathi esifushane kakhulu sokugaya, umshini wokugaya ukhiqiza ukucindezela okukhulu kwangaphakathi, futhi ukungqubuzana okuphuthumayo kuyanda, okuholela ku-The friction enkulu. ukushisa kwandisa izinga lokushisa lengxube, okungadala kalula ukuthi itiyela liguge. Kukhona nengxenye encane engazange igaywe ngokwanele futhi ikhishwe ngokuqondile ethangini lokugaya. Lokhu kunomthelela oqondile ekucoliseni, ikhwalithi, kanye nezinga lokugeleza kwetiyela elishintshiwe, futhi kufinyeza kakhulu impilo yomshini wokugaya.
Ngakho-ke, akunakugwenywa futhi kuyadingeka ukuthuthukisa inqubo yebitumen eguquliwe kanye nemishini. Ukuze kunqotshwe izinkinga ezivamile ekucutshungulweni kwezinto eziguquliwe zokuhlanganisa itiyela, inkampani yethu ithuthukise ukwakheka kwenqubo yokukhiqiza itiyela eguquliwe futhi yenza ukuthuthukiswa kwesakhiwo ku-homogenizer nomshini wokugaya. Ngokuhlola kanye nesikhathi sokukhiqiza, kuye kwafakazelwa ukuthi izinkinga ezingenhla zingaxazululwa ngokuphelele. Sisebenzise ubuchwepheshe bokukhiqiza obuthuthukisiwe ukuze sakhe iqoqo lezinto zebitumen ezilungisiwe zekhwalithi ephezulu, okuthuthukise ukusebenza kahle kokukhiqiza futhi kwanciphisa kakhulu ukusetshenziswa kukagesi namandla okushisa, okunomthelela othile ekongiweni kwamandla. Abasebenzisi abasha nabadala bamukelekile ukusishayela ukuze sibonisane.
