Inqubo eyisisekelo yokukhiqiza yengxube ye-asphalt ihlanganisa ukucwiliswa kwamanzi, ukushisa nokumboza i-aggregate nge-asphalt eshisayo. Imishini yayo yokukhiqiza ingahlukaniswa ngokuyisisekelo ibe izinhlobo ezimbili ngokwendlela yokusebenza: uhlobo lwesikhashana (ukuxuba nokukhipha ebhodweni elilodwa) kanye nohlobo oluqhubekayo (ukuxuba okuqhubekayo nokukhipha).

Izingxenye ezisetshenziselwa ukumboza i-aggregate eshisayo nge-asphalt eshisayo kulezi zinhlobo ezimbili zemishini yokuxuba i-asphalt zingase zehluke, kodwa uma kuziwa ekomisweni nasekushiseni izinhlelo, zombili izinhlobo ezihamba kancane neziqhubekayo zakhiwe izingxenye ezifanayo eziyisisekelo, futhi izingxenye zazo eziyinhloko ziyi izigubhu zokomisa, izibasi, iziphephetha-moya ezikhangiwe, izinto zokususa uthuli kanye nemitshingo. Nansi ingxoxo emfushane yamagama athile ochwepheshe: imishini yezitshalo yokuxuba itiyela ngezikhathi ezithile iqukethe izingxenye ezimbili ezihlukene, eyodwa isigubhu kanti enye iyisakhiwo esikhulu.
Isigubhu sihlelwe emthambekeni omncane (ngokuvamile ama-3-4 degrees), ne-burner efakwe ekugcineni okuphansi, futhi i-aggregate ingena kusukela ekupheleni kancane kwesigubhu. Ngesikhathi esifanayo, umoya oshisayo ungena esigubhu usuka ekugcineni komshini wokushisisa, futhi ipuleti eliphakamisayo ngaphakathi kwesigubhu liphendulela ukuhlanganisa ngokugeleza komoya oshisayo ngokuphindaphindiwe, ngaleyo ndlela kuqedele inqubo yokukhipha umswakama kanye nokushisisa kwenhlanganisela esigubhu.
Ngokulawulwa okusebenzayo kwezinga lokushisa, ama-aggregate ashisayo nokomile anezinga lokushisa elifanele adluliselwa esikrinini esidlidlizayo esingaphezulu kwesakhiwo esikhulu, futhi izinhlayiya ezinosayizi abahlukene zihlolwa isikrini esidlidlizayo bese ziwela emigqonyeni yokugcina ehambisanayo, bese ingena. ibhodwe lokuxuba lokuxuba ngokuhlukanisa nokukala. Ngesikhathi esifanayo, i-asphalt eshisayo kanye ne-mineral powder eye yalinganiswa nayo ingena ebhodweni lokuxuba (ngezinye izikhathi liqukethe izithasiselo noma imicu). Ngemuva kwesikhathi esithile sokuxuba ku-tank yokuxuba, ama-aggregates ambozwe ungqimba lwe-asphalt, bese kwakhiwa ingxube ye-asphalt eqediwe.
