Inkampani yethu isineminyaka eminingi ibambe iqhaza ekukhiqizeni imishini yokuhlanza itiyela. Umshini wokukhipha itiyela unezici zokubhoboza ngokushesha, ukuvikela okuhle kwemvelo, akukho ukulengiswa komgqomo, ukuguquguquka okuqinile, ukuphelelwa amanzi emzimbeni, ukususwa kwe-slag okuzenzakalelayo, ukuphepha nokuthembeka, kanye nokufuduka kalula.
Kodwa-ke, i-asphalt ingumkhiqizo onezinga lokushisa eliphezulu. Uma isetshenziswe ngendlela engafanele, kulula kakhulu ukubangela imiphumela emibi. Ngakho yimiphi imithetho okufanele siyilandele lapho sisebenza? Ake sibuze ochwepheshe abaqeqeshiwe ukuthi basisize sichaze:

1. Ngaphambi kokusebenza, izidingo zokwakha, izindawo zokuphepha ezizungezile, ivolumu yokugcina i-asphalt, izingxenye zokusebenza, izinsimbi, amaphampu e-asphalt, nezinye izinto zokusebenza zomshini wokubhoboza kufanele zihlolwe ukuze kubonakale ukuthi zijwayelekile yini. Kuphela uma lingekho iphutha ingasetshenziswa ngokujwayelekile.
2. Umgqomo we-asphalt kufanele ube nokuvuleka okukhulu ekugcineni komunye kanye ne-vent ngakolunye uhlangothi ukuze umgqomo ukwazi ukungena umoya lapho umgqomo ukhishwa futhi i-asphalt ingamuncwa.
3. Sebenzisa ibhulashi locingo noma enye into ukuze ususe inhlabathi nokunye ukungcola okunamathiselwe ngaphandle komgqomo ukunciphisa i-slag emgqonyeni.
4. Emishinini ye-asphalt yokushisa eshubhu noma eqondile, izinga lokushisa kufanele liphakanyiswe kancane ekuqaleni ukuvimbela i-asphalt ekuchichimeni ibhodwe.
5. Lapho umshini we-asphalt barreling oshisa i-asphalt ngamafutha okudlulisa ukushisa uqala ukusebenza, izinga lokushisa kufanele liphakanyiswe kancane ukuze likhiphe amanzi emafutheni okudlulisa ukushisa, bese uwoyela wokudlulisa ukushisa kufanele ungeniswe emshinini wokubhoboza ukuze ususe imiphongolo. .
6. Ngomshini wokubhoboza osebenzisa igesi engcolile ukuze ususe imiphongolo, ngemva kokuba yonke imiphongolo ye-asphalt ingena ekamelweni lokubhoboza, umshini wokuguqula igesi emfucumfucu kufanele uguqulwe ohlangothini lwegumbi lokubhoboza. Lapho imiphongolo engenalutho ikhishwa futhi igcwaliswa, inkinobho yokuguqula igesi engcolile kufanele iguqulelwe ohlangothini oluholela ngqo kushimula.
7. Lapho izinga lokushisa le-asphalt ekamelweni le-asphalt lifinyelela ngaphezu kuka-85 ° C, ipompo ye-asphalt kufanele ivulwe ukuze ijikeleze ngaphakathi ukuze kuphuthunyiswe izinga lokushisa kwe-asphalt.
8. Ngomshini wokukhipha i-bitumen oshisa ngokuqondile izinga lokushisa lokuhlola, kungcono ukungapompa i-asphalt ekhishwe kunqwaba yemiphongolo ye-asphalt, kodwa ukuyigcina njenge-asphalt ukuze ijikeleze ngaphakathi. Esikhathini esizayo, inani elithile le-asphalt kufanele ligcinwe isikhathi ngasinye lapho i-asphalt iphonswa, ukuze i-asphalt isetshenziswe ngokushesha ngangokunokwenzeka ngesikhathi sokushisa. Iphampu ye-asphalt isetshenziselwa ukujikeleza kwangaphakathi ukusheshisa izinga lokuncibilika nokushisa kwe-asphalt.
