Kunemikhiqizo eminingi yezitshalo zokuxuba i-asphalt ngokuya ngabakhiqizi kanye nokucaciswa. Uma sikhetha isitshalo sokuxuba i-asphalt, kufanele sivumelane nezimo zendawo futhi sikhethe imikhiqizo eneziqhathaniso zamanani ezikhethiwe ngokusekelwe ezidingweni zesayizi yesayithi kanye nesilinganiso sokukhiqiza. Awukwazi nje ukuphishekela ikhwalithi, futhi awukwazi nje ukuphishekela intengo ephansi. Izici ezilandelayo kufanele zicatshangelwe lapho kukhethwa isitshalo sokuxuba i-asphalt.

Ukukhethwa kwesitshalo sokuxuba i-asphalt kusekelwe ikakhulukazi ekuthembekeni nasekusebenziseni izinto ezihlukahlukene zemishini. Kudinga futhi ukunemba kwesilinganiso esiphakeme, ikhwalithi enhle yokuxuba, ukusebenza kahle kokukhiqiza okuphezulu, ukusetshenziswa kwamandla okuphansi, njll.

Amandla okukhiqiza esitshalo se-asphalt ahlulelwa ngokuya ngobukhulu besikali sokukhiqiza.

Kuye ngobukhulu bendawo yokwakha, isakhiwo sesitshalo sokuxuba i-asphalt noma isitshalo sokuxuba i-asphalt singakhethwa. Uma ukhetha isitshalo sokuxuba i-asphalt, i-aggregate idinga ukuthuthukiswa kabili, ukuhlelwa kuyavumelana nezimo, umjikelezo wokukhiqiza nokufaka umfushane, futhi izindleko zokutshala izimali zesikhathi esisodwa ziphansi.

Akuhlakaniphile ukuphishekela ngokugcwele ukusebenza kwezobuchwepheshe kwemishini, okuzokwandisa ukutshalwa kwezimali okungadingekile. Kodwa-ke, ukuphishekela ukutshalwa kwezimali okuphansi kuphela nokunciphisa ukusebenza kwezobuchwepheshe kwemishini kuzokhuphula izindleko zokusebenzisa, nakho okungafuneki. Kunengqondo ukukhetha isilinganiso esilungile sentengo/sokusebenza.

Izitshalo zokuxuba i-asphalt zihlukaniswa ngokuvumelana nokugeleza kwenqubo: ukuxuba okuphoqelekile okuphakathi nokuqhubekayo, kanye nohlobo lwesigubhu ngokuziphonsa okuqhubekayo kokuxubana. Ngokwesimo sayo sokufakwa, ingahlukaniswa ngohlobo olumisiwe kanye nohlobo lweselula. Ngaphambilini, wonke amayunithi afakwe endaweni ethile futhi asetshenziswa kakhulu ezimeni lapho amaphrojekthi amakhulu agxiliwe. Eyakamuva inkulu futhi inosayizi omaphakathi, nawo wonke amayunithi afakwe kuma-trailer amaningana akhethekile ane-flatbed, adonselwa endaweni yokwakha abese ehlanganiswa futhi amiswe, futhi asetshenziswa kakhulu emisebenzini yokwakha umgwaqo omkhulu; kwabancane, iyunithi ifakwe ku-trailer ekhethekile ye-flatbed, engakwazi Ukudluliselwa nganoma yisiphi isikhathi futhi isetshenziswa kakhulu kumaphrojekthi wokulungiswa komgwaqo. Imishini yokuxuba ukhonkolo yohlobo lwesigubhu yasungulwa ngeminyaka yawo-1970. Ibonakala ngokomiswa okuqhubekayo, ukushisa nokuxuba isihlabathi namatshe esigubhu. I-burner ifakwe phakathi nendawo ekugcineni kokuphakelayo kwesigubhu futhi iyashiswa eduze nokugeleza kwezinto. Uketshezi lwe-asphalt olushisayo lufuthwa engxenyeni engaphambili yesigubhu, luxutshwe nesihlabathi esishisayo netshe ngendlela eziziwisela yona bese lidedelwa, okungagcini nje ngokwenza kube lula inqubo kodwa futhi kunciphisa ukundiza kothuli. Imikhiqizo eqediwe engalayishiwe igcinwa endaweni yokugcina impahla eqediwe ukuze isetshenziswe kamuva. Lolu hlobo lwemishini yokuxuba lusebenzise ubuchwepheshe be-elekthronikhi kanye nezinsimbi ezintsha zokuhlola eminyakeni yamuva, ezingakwazi ukubona ukukhiqiza okuzenzakalelayo futhi zilawule ngokuqinile isilinganiso sokuxuba ukuze kuqinisekiswe ikhwalithi yomkhiqizo oqediwe.

Ngemva kokufunda lokhu, ingabe unokuqonda okujulile ngezitshalo zokuxuba itiyela?
