Umgaqo osebenzayo wokumisa kunye nenkqubo yokufudumeza kwisityalo sokuxuba i-asphalt
Inkqubo esisiseko yokuvelisa umxube we-asphalt iquka ukuchithwa kwamanzi, ukufudumeza kunye nokugubungela i-aggregate nge-asphalt eshushu. Izixhobo zayo zokuvelisa zinokuthi zihlulwe ngokwesiseko zibe ziindidi ezimbini ngokwendlela yokusebenza: uhlobo oluphakathi (ukuxuba kunye nokukhupha kwimbiza enye) kunye nohlobo oluqhubekayo (ukuxuba ngokuqhubekayo kunye nokukhupha).
Amalungu asetyenziselwa ukugubungela i-aggregate eshushu kunye ne-asphalt eshushu kwezi ntlobo zimbini zezixhobo zokuxuba i-asphalt zinokwahluka, kodwa xa kuziwa ekumiseni kunye neenkqubo zokufudumeza, zombini iintlobo eziphazamisayo kunye neziqhubekayo zenziwe ngamacandelo asisiseko afanayo, kwaye amacandelo abo aphambili amagubu okomisa, izitshisi, iifeni ezifunxayo, izixhobo zokususa uthuli kunye nemibhobho. Nantsi ingxoxo emfutshane yamagama athile achwephesha: izixhobo zesityalo sokuxuba i-asphalt zibandakanya iinxalenye ezimbini ezahlukeneyo, elinye ligubu kwaye elinye lisona sakhiwo siphambili.
Umgqomo ulungiselelwe kwi-slope encinci (ngokuqhelekileyo i-3-4 degrees), kunye ne-burner efakwe kwisiphelo esisezantsi, kwaye i-aggregate ingena ukusuka ekupheleni kancinci kwi-drum. Ngelo xesha, umoya oshushu ungena kwi-drum ukusuka ekupheleni kokushisa, kwaye i-plate yokuphakamisa ngaphakathi kwi-drum ijika i-aggregate ngokusebenzisa ukuhamba komoya oshushu ngokuphindaphindiweyo, ngaloo ndlela igqibezela inkqubo yokucima kunye nokufudumala kwe-aggregate kwi-drum.
Ngokulawulwa kobushushu obusebenzayo, ii-aggregates ezishushu nezomileyo ezinobushushu obufanelekileyo zikhutshelwa kwiscreen esingcangcazelayo phezulu kwesakhiwo esikhulu, kwaye amasuntswana obungakanani obahlukeneyo ahluzwa yiscreen sokungcangcazela aze awele kwimigqomo yokugcina ehambelanayo, emva koko ungene. imbiza yokuxuba yokuxuba ngokuhlela kunye nokulinganisa. Ngelo xesha, i-asphalt eshushu kunye ne-mineral powder elinganisiweyo iphinda ingene kwi-pot yokuxuba (ngamanye amaxesha iqulethe izongezo okanye iifibers). Emva kwexesha elithile lokuxuba kwi-tank yokuxuba, i-aggregates ihlanganiswe ne-asphalt layer, kwaye emva koko umxube we-asphalt ogqityiweyo wenziwa.
