Ngokuqiniswa komkhuba wokuvikelwa kwemvelo kanye nokongiwa kwamandla, ukuvikelwa kwemvelo kweziteshi zokuxuba i-asphalt kancane kancane sekuyindlela evamile yokuthuthukiswa kwesiteshi sokuxuba. Hlobo luni lwemishini engabizwa ngokuthi isiteshi sokuxuba ukhonkolo se-asphalt esivumelana nemvelo? Yiziphi izimo eziyisisekelo okufanele zihlangatshezwe?

Okokuqala nje, njengesiteshi sokuxuba ukhonkolo se-asphalt esivumelana nemvelo, kufanele sihlangabezane nemfuneko yokusebenzisa amandla amancane ngesikhathi sokusetshenziswa. Okusho ukuthi, ngaphansi kwezimo zobuningi nekhwalithi efanayo, amandla amancane asetshenziswa ngesikhathi sokusebenza, kuhlanganise nezinsiza ezihlukahlukene ezifana namanzi nogesi.
Okwesibili, iziteshi zokuxuba ukhonkolo we-asphalt ezinobungani bemvelo azidingi nje kuphela ukusetshenziswa kwamandla amancane, kodwa futhi kufanele zifinyelele ukusebenza kahle kokukhiqiza, futhi ngesikhathi esifanayo zinciphise ukukhishwa kwekhabhoni kuyo yonke inqubo yokukhiqiza, ukuze kuhlangatshezwane nezidingo ezihlongozwayo zokukhiqiza ikhabhoni ephansi.
Ngaphezu kwalokho, yilabo kuphela abangakwazi ukulawula ngempumelelo ukungcola okukhiqizwe futhi banciphise umonakalo oqondile emvelweni obangelwa ukungcola okukhiqizwa ngesikhathi sokukhiqiza abafanelekela ukuchazwa njengeziteshi zokuxuba ukhonkolo we-asphalt ezinobungani bemvelo. Kukhona nezidingo zokuhlelwa kwezitshalo zayo, noma ngabe kuyindawo yokukhiqiza noma indawo yokuguqulwa kwamanzi angcolile kanye negesi engcolile, kufanele kube okunengqondo.
Imvamisa, iziteshi zokuxuba ukhonkolo we-asphalt ezinobungani bemvelo, njengeziteshi ezijwayelekile zokuxuba ukhonkolo we-asphalt, nazo zingahlukaniswa zibe izinhlobo ezimaphakathi neziqhubekayo. Kodwa kungakhathaliseki ukuthi iyini ifomu, ingaxuba futhi inyakaze ama-aggregate omisiwe futhi ashisayo osayizi bezinhlayiyana ezahlukene, ama-fillers kanye ne-asphalt ibe ingxube efanayo ngokuvumelana nesilinganiso sokuxuba esiklanyelwe ekushiseni okucacisiwe.
Iqoqo eliphelele kuphela lezitshalo zokuxuba ukhonkolo ze-asphalt ezinobungani bemvelo ezihlangabezana nalezi zimo zemvelo kanye nezidingo zokusebenza ezingasetshenziswa kabanzi kwezinye izakhiwo zobunjiniyela ezifana nemigwaqo emikhulu yezinga eliphezulu, imigwaqo yasemadolobheni, izikhumulo zezindiza, amadokhu, izindawo zokupaka, njll., futhi uqinisekise ukuthi izinga lokugandaywa kwetiyela.
