Ukwakhiwa komgwaqo ngokuvamile kuwumsebenzi omkhulu wokutshala izimali. Ngesikhathi sokwakhiwa kwangempela kwephrojekthi, kudingekile kakhulu ukulawula izindleko zephrojekthi. Ukulawula nokuphatha izindleko zesikhungo sokuxuba itiyela kuphrojekthi yomgwaqo kunomthelela omkhulu ekulawuleni izindleko zayo yonke iphrojekthi yomgwaqo, ngoba izindleko eziyinhloko zephrojekthi yomgwaqo zigxile embonini yokuxuba itiyela,  futhi cishe nawo wonke umgwaqo. amaphrojekthi asetshenziswa izinto axhumene eduze izitshalo asphalt.

Intengo ayisekho ukuphela kwesici sokuthenga izitshalo zokuxuba i-asphalt, manje abathengi bakhokha kakhulu izindleko zokusebenza zayo. ukulawula izindleko zesikhungo sokuxuba itiyela kufanele kuqale kusabelomali sephrojekthi yephrojekthi yomgwaqo. Lapho wenza isabelomali sesitshalo sokuxuba i-asphalt, umthelela wezinto ezahlukahlukene ezindlekweni kufanele ubhekwe ngokugcwele, njengokuthi: indawo efanelekile, izinto zokukhiqiza i-asphalt, izikimu zokuhamba, imishini yokukhiqiza, inqubo yokukhiqiza esigabeni sesabelomali, Kudinga abaphathi nekhono ezidingweni zobuchwepheshe namandla esabelomali ukwenza amabhajethi ezindleko zokukhiqiza eziphusile, nokuthuthukisa izinhlelo zokukhiqiza zebhizinisi ngalinye ngesisekelo sokuqinisekisa ikhwalithi yokukhiqiza, ngaleyo ndlela kuncishiswe izindleko zokukhiqiza.

Ngesikhathi sokusebenza kwemboni yokuxuba itiyela, okokuqala, indima yokuxhumanisa izisebenzi kufanele isetshenziswe ngokugcwele, futhi opharetha abafanelekile kufanele bahlonyiselwe ukusebenza kwemishini ehlukene, ukuze kugwenywe izindleko ezengeziwe zokukhiqiza ngenxa yokusebenzisa kabi abasebenzi.

Okwesibili, lapho ushisa i-asphalt aggregate, idinga inani elikhulu lezinto zamandla. Esikhathini samanje, imithombo yamandla iya ngokuya ishuba, futhi izindleko zezinto zamandla zikhula njalo. Ngakho-ke, kuyadingeka ukwenza izinqumo ezifanele zalezi zinto zamandla. Ukukhethwa okunengqondo kwezinto zamandla ngendlela eyongayo kungalawula ngokuphumelelayo izindleko zokukhiqiza izitshalo zokuxuba i-asphalt ngenkathi kuthuthukiswa ukusetshenziswa kahle kwezinto zamandla.

Okwesithathu, ekwakhiweni komgwaqo, inani lezinto ezihlukahlukene zezitshalo ze-asphalt  likhulu kakhulu, ngakho-ke izindleko zokuhamba nazo ziphezulu kakhulu, ngakho-ke kuyadingeka ukwenza uhlelo olufanele lokuthutha lwezinto ezisetshenziswayo, ukuze ugweme ukumosha nokufeza umgomo. yokulawula izindleko . Ukuze kusetshenziswe ukulawulwa kwezindleko zezinto zokuthutha, umnyango okhethekile wokuqondisa ezokuthutha ungamiswa ngesikhathi sokuthutha izinto ezisetshenziswayo ukuze wenze umthethonqubo ophusile kwezokuthutha.

Ngaphezu kwalokho, ngaphambi kokukhiqizwa okukhulu kwengxube ye-asphalt, ukunakwa okukhethekile kufanele kukhokhwe: Ukushisa kwebhodwe lokuxuba akufanele kube phansi kakhulu, ngaphandle kwalokho izingxube ze-asphalt ezikhiqizwa ebhodweni lokuxuba zizobe zingafaneleki, okuzoletha imfucuza ye-aluminium. ingxube ye-alloy isetshenziswa. futhi kufanele kuqashelwe ukusetshenziswa okufanele kwezinto ezisetshenziswayo ze-aluminium ezibandayo nezishisayo. Gwema ukukhuphuka kwezindleko okubangelwa ukusetshenziswa okungafanele kwamabhuloho okugibela.

Sekukonke,Lapho kwenziwa ukukhiqizwa ngobuningi bezingxube zetiyela, kuyadingeka ukukala izici ezihlukahlukene ezithinta izindleko zokukhiqiza.Ngemva kokuba isabelomali sezindleko zokukhiqiza sesiqediwe,  konke ukukhiqizwa kufanele kwenziwe ngokohlelo olubekelwe isabelomali, kanye nasenqubweni yokukhiqiza yangempela. , kuyadingeka ukuqaphela ngokugcwele: Nikeza umdlalo ogcwele endimeni yokuxhumanisa yazo zonke izici, ukuhlela ngokunengqondo izinto zokukhiqiza, khetha izinto ezisetshenziswa amandla ezifanele, nezinketho zokuthutha ezibonakalayo ezinengqondo, futhi unake imininingwane yenqubo yokuhlanganisa, ukuze uthole ngempela. ukuzuza ukulawula okuphumelelayo nokuzwakalayo kwezindleko zokukhiqiza.
