Izinhlobo ezimbili ze Imisebenzi yezitshalo zokuxuba i-asphalt noma ukusebenza okufanayo. Isimiso esiyisisekelo sanoma yiluphi uhlobo lwesitshalo se-asphalt siyefana i.e. ukukhiqiza i-asphalt yengxube eshisayo. Okuhlukile kulele endleleni umkhiqizo wokugcina olungiswa ngayo. Eminye yemisebenzi evamile yazo zombili izinhlobo zezitshalo ze-asphalt yilezi:
- Osayizi abahlukene beqoqo lokuqoqa nokuphakela emigqonyeni.
- Ukuhlolwa kwama-aggregate. Ngohlobo oluqhubekayo ama-aggregate ayahlolwa ukuze kukhishwe usayizi. Ngenkathi kuhlobo lwe-batch ama-aggregate ayahlolwa ukuze ahlukaniseke ezingxenyeni ezihlukene.
- Ukomisa nokushisisa ama-aggregates.
- Ukuncibilika kokugcinwa nokudluliselwa kwetiyela
- Ukugcinwa nokudluliswa kwezinto zokugcwalisa.
- Ibitumen, ama-aggregates kanye nezinto zokugcwalisa kukalwa ngezitshalo zohlobo lwe-batch. Lapho ezitshalweni zohlobo oluqhubekayo zengezwa futhi zilawulwa yi-variable frequency drive.
- Ukukhishwa kwe-asphalt yengxube eshisayo elolini noma esiseleni sokugcina.
- Iphaneli yokulawula ijwayelekile kuzo zombili izinhlobo. Ilawula imisebenzi yesitshalo futhi isinika umbiko wamapharamitha abalulekile.
Izinto Ezine Eziyisisekelo Zokusebenza Kwezimboni Zokuxuba I-Asphalt:
Kukhona izinto eziyisisekelo ezivamile kuzo zonke izitshalo zokuxuba i-asphalt. Zimi kanje ngezansi:
- Ukomisa nokushisisa ama-aggregates.
- Isisindo sama-aggregate, itiyela kanye nezinto zokugcwalisa.
- Ukuhlanganisa ama-aggregate ngebitumen nezinto zokugcwalisa.
- Ukukhishwa kwe-hot mix asphalt.
Kunoma yiluphi uhlobo lwesitshalo se-asphalt ukunemba kwesisindo kuyisici esiyinhloko. Kufanele kube nesisindo esingaguquki nesinembile samaqoqo, itiyela kanye namaminerali. Uma ukukala kuvumelana, sithola umkhiqizo wokugcina esiwufunayo onjengokulindelwe nezinkambiso. Kuyasiza ekwakheni imigwaqo engcono ngokwemithetho ebekiwe. Isitshalo se-asphalt sinamandla okugcina izindlela zokupheka ezahlukene. Singashintsha ukusebenzisa izindlela zokupheka ezihlukene zezinhlelo zokusebenza ezahlukene uma kudingeka. Ngisho kubalulekile ukuqaphela ukuthi ukugcinwa nokusetshenziswa kwamaresiphi amaningi kubalulekile uma usebenzisana namakhasimende amaningi. Uma unamaresiphi amakhasimende ahlukene agcinwe nawe kuba lula ukukhetha noma iyiphi iresiphi ethile edingekayo. Uma iresiphi oyifunayo isikhethiwe ngokuchofoza okumbalwa kungenzeka ukwenza i-AMP ikhiqize ikhwalithi edingekayo ye-hot mix asphalt.
Ukuphumelela kwanoma yisiphi isitshalo sokuxuba i-asphalt kudinga ibhalansi eyanele kanye nokuxhumana kwazo zonke izingxenye. Kusukela i isitshalo se-asphalt iyinhlanganisela yezinto eziwumshini nezikagesi. Kubalulekile ukuthi zonke izingxenye zisebenze ngokuhambisana ukuze zinikeze imiphumela oyifunayo. Kungenzeka ukuthola ukuvumelana nokulinganisela ngokuqaphela ukuqapha nokuphatha. Kubalulekile ukuhlola zonke izingxenye zesitshalo ngaphambi kokuqala. Kubalulekile ukwenza ukunakekelwa kwansuku zonke, kwamasonto onke, kwanyanga zonke njengoba kuchazwe umenzi ngezikhathi ezithile. Zonke izinto ezinjengama-aggregate, uphethiloli, itiyela kufanele zihlolwe izinga ngaphambi kokusetshenziswa. Uma kuqashelwa ukuqapha kulula ukwenza izinto ezixubene nekhwalithi kusuka ku-hot mix plant yanoma iyiphi inkampani enhle.
I-Atlas ingumkhiqizi osuselwe eNdiya kanye nomkhiqizi wesitshalo sokuxuba i-asphalt.
Yiziphi izingxenye ze-hot mix asphalt?
I-hot mix asphalt iqukethe amatshe anobukhulu obuhlukahlukene, amatshe, itiyela kanye ne-binder material. I-Hot mix asphalt ilungiswa ngokushisisa itiyela, ama-aggregates futhi awaxube emazingeni okushisa aphakeme.
Yiziphi izinhlobo ezi-2 zetiyela?
Izinhlobo ezi-2 eziphambili zetiyela ziyingxube eshisayo kanye nohlobo lwengxube ebandayo. I-Hot mix asphalt ilungiswa ishisa futhi ibekwe ngaphambi kokuthi iphole. I-asphalt yengxube ebandayo ayishisi - ikhiqizwa ngokuxuba i-emulsion, amanzi noma usimende. Ama-aggregate asetshenziswa ku-cold mix asphalt awashiswa.
Uyini umehluko phakathi kwe-asphalt nebitumen?
Ibitumeni iwuketshezi olungaphekiwe olusetshenziselwa ukukhiqiza itiyela elixubene elishisayo. I-asphalt iyinhlanganisela ye-aggregate, isihlabathi nebitumen ezingeni lokushisa eliphezulu. Ibitumen isebenza njengento ehlanganisayo ekukhiqizeni usimende we-asphalt.
