Kungani Izitshalo Ze-Asphalt Zivala Ebusika?

Ukuqonda Ukuvalwa Kwezitshalo Ze-Asphalt Kwesizini

Njengoba izinyanga zasebusika zisondela, izimboni eziningi ziqala ukwehla, futhi umkhakha wokukhiqiza i-asphalt nawo awuhlukile. Uma wake wazibuza ukuthi, “Kungani izitshalo ze-asphalt zivalwa ebusika?” awuwedwa. Lokhu kuvalwa kwesizini kuyinto evamile, kodwa izizathu zalokhu zinezici eziningi. Ake sikuchaze futhi sihlole izici ezibalulekile eziholela ekuvalweni kwezitshalo ze-asphalt phakathi nezinyanga ezibandayo.

Isimo Sezulu Esibandayo Nokukhiqizwa Kwe-Asphalt

Esinye sezizathu eziyinhloko ezenza izitshalo ze-asphalt zivalwe ebusika yizinselele ezibangelwa isimo sezulu esibandayo. I-asphalt iyinto ezwela ukushisa, futhi ukukhiqizwa kwayo kanye nokusetshenziswa kwayo kudinga izimo ezithile. Lapho amazinga okushisa ehla, i-viscosity ye-asphalt iyanda, okwenza kube nzima ukuyixuba nokuyifaka. Ngaphezu kwalokho, izinto ezisetshenziswa ekukhiqizeni i-asphalt, njenge-aggregate kanye ne-binder, zizwela amazinga okushisa abandayo, okungathinta ikhwalithi yomkhiqizo wokugcina.

Ukutholakala Kwezinto Ezibalulekile Nezindleko

Esinye isici esibalulekile ukutholakala kanye nezindleko zezinto zokusetshenziswa ebusika. Izakhi eziningi ezisetshenziswa ekukhiqizeni i-asphalt, njengezinto zokuhlanganisa kanye nezinhlanganisela ezisekelwe kuphethiloli, zibiza kakhulu ukuzithenga phakathi nezinyanga ezibandayo. Izindleko zokuhamba nazo ziyakhuphuka ngenxa yemigwaqo ebandayo kanye nezimo zezulu ezimbi, okwandisa kakhulu izindleko zokulungisa imisebenzi.

Isidingo Sokwakha kanye Nemisebenzi Yesizini

Izitshalo ze-asphalt zisiza kakhulu imboni yokwakha, ebhekana nokwehla kwemvelo ebusika. Njengoba kunezinhlelo zokwakha ezimbalwa eziqhubekayo, isidingo semikhiqizo ye-asphalt njenge-hot mix asphalt (HMA) kanye ne-warm mix asphalt (WMA) sincipha kakhulu. Lokhu kuncipha kwesidingo kwenza kube nzima ngokwezomnotho ukuthi izitshalo ze-asphalt ziqhubeke nokusebenza.

Ukugcinwa Nokugcinwa Kwemishini

Ubusika buphinde bunikeze ithuba lokuthi izitshalo ze-asphalt zenze ukulungiswa nokulungiswa okudingekayo. Ukusebenza okuqhubekayo kwemishini esindayo kungaholela ekugugeni nasekuqhekekeni, kanti ukuvalwa kwebusika kuvumela izitshalo ukuthi zihlole, zisevise, futhi zithuthukise imishini yazo. Lesi sikhathi sokungasebenzi siqinisekisa ukuthi isitshalo sisesimweni esihle kakhulu lapho imisebenzi iqala kabusha entwasahlobo.

Izinto Ezicatshangelwayo Kwezemvelo Nokuphepha

Isimo sezulu esibandayo singadala nezinselele zemvelo kanye nokuphepha. Ukukhiqizwa kwe-asphalt kukhiqiza ukukhishwa kwegesi, futhi emakhazeni amakhulu, lokhu kukhishwa kwegesi kungaba okugxile kakhulu, okungenzeka kwephule imithethonqubo yemvelo. Ngaphezu kwalokho, izimo ezibandayo kanye namazinga okushisa abandayo kwandisa ingozi yezingozi kubasebenzi basefektri. Ukuvala isitshalo ebusika kusiza ekunciphiseni lezi zingozi.

Ukuhlela Amasu Esizini Ezayo

Okokugcina, ukuvalwa kwebusika kuvumela izitshalo ze-asphalt ukuthi zihlele kahle isizini yokwakha ezayo. Lesi sikhathi sisetshenziselwa ukuhlaziya ukusebenza konyaka odlule, ukuhlola isidingo semakethe, nokulungiselela noma yiziphi izinguquko emithethweni noma kubuchwepheshe. Ngokuthatha ikhefu, izitshalo zingabuya ziqine futhi zisebenza kahle entwasahlobo.

Isiphetho

Ngakho-ke, kungani izitshalo ze-asphalt zivalwa ebusika? Impendulo ilele ekuhlanganiseni kwezinto, okuhlanganisa izinselele zesimo sezulu esibandayo, ukutholakala kwezinto ezibonakalayo, ukuncipha kwesidingo, izidingo zokulungisa, ukukhathazeka ngemvelo, kanye nokuhlela amasu. Nakuba ukuvalwa kungase kubonakale kungafanele, kuyisinyathelo esidingekayo ukuqinisekisa ikhwalithi, ukuphepha, kanye nokusebenza kahle kokukhiqizwa kwe-asphalt lapho imisebenzi iqala kabusha.
