Kungani imishini yokuxuba i-asphalt kufanele isebenze ngokuhambisana nemithethonqubo
Isikhathi Sokukhipha:2023-09-27
Ukugeleza kwenqubo yesitshalo sokuxuba i-asphalt kufanele kwaziwe kuwo wonke umuntu. Umhleli wabaxube abakhulu ucabanga ukuthi ukukhiqizwa kwemishini yokuxuba i-asphalt kunqunywa umthamo we-cylinder wokuxuba kanye nomjikelezo wokusebenza. Umjikelezo wokusebenza ubhekisela kumehluko wesikhathi kusukela ekuphumeni kwethangi lokuxuba ukuya esikhathini esilandelayo sokulahla. Imishini yokuxuba itiyela iklanywe ngokuhlangene ngezigubhu ezomisa ngezikhathi ezithile kanye nezigubhu zokuxuba ukuze kwehliswe izindleko zokutshala imali kumakhasimende.
Imishini yokuxuba i-asphalt iyisethi ephelele yesitayela sefekthri ehlanganisa inhlanganisela eyomile neshisayo yobukhulu bezinhlayiyana ezihlukene, izigcwalisi kanye ne-asphalt ngokwesilinganiso semiksi eklanyelwe ezingeni lokushisa elicacisiwe libe yingxube efanayo. Isetshenziswa kabanzi emigwaqweni emikhulu, emigwaqweni yasemadolobheni, ezikhumulweni zezindiza, Isetshenziswa ekwakhiweni kwamadokodo, izindawo zokupaka kanye namanye amaphrojekthi, imishini yokuxuba i-asphalt iyithuluzi elibalulekile nelibalulekile lokuhamba ngetiyela. Ukusebenza kwayo kuthinta ngqo ikhwalithi ye-asphalt pavement.
Ngokuvamile, imishini yokuxuba ukhonkolo we-asphalt inezinhlobo ezimbili: uhlobo lwesikhashana kanye nohlobo oluxhunyiwe. Uhlobo oluxhunyiwe lunomsebenzi wenqubo olula kanye nemishini eyenziwe lula. Ngokuqondene nemishini yokuxuba i-asphalt ngezikhathi ezithile, ngenxa yokuhlolwa kwesibili kwama-aggregates, izakhi ezihlukahlukene zilinganiswa ngamaqoqo, futhi ama-aggregate aphoqeleka ukuba axutshwe futhi axutshwe, angaqinisekisa ukuhlukaniswa kwezinto, kanye nokulinganisa kwe-powder ne-asphalt futhi ukufinyelela ezingeni eliphezulu kakhulu. Ngokunemba okuphezulu, ingxube ye-asphalt exubile iyikhwalithi enhle futhi ingahlangabezana nezidingo zezakhiwo ezihlukahlukene.
Izinto zokusebenza zisekelwe kumqondo wokuvikelwa kwemvelo wamazinga aseYurophu, ukunikeza amakhasimende isiqinisekiso sokuthi okokusebenza kuhlangabezana ngokugcwele nezindinganiso maqondana nokukhipha uthuli, ukukhishwa kwe-acidic kanye nokulawula umsindo.
