Ngemuva kokuthi isitshalo sokugcina i-asphalt se-rubber sihlanjululwe, ama-chips ezinkuni athunyelwa endaweni yokugcina i-asphalt ye-raber, futhi ama-chips ezinkuni kanye nangaphansi kwesitshalo sokugcina i-asphalt yerabha kusulwa ngamapulangwe ezinkuni. Ukungcola namapulangwe okhuni ethangini le-asphalt kungabekezelelwa ngokwemvelo. Isitshalo sokugcina i-asphalt yerabha asivunyelwe ukuba sonakaliswe. Hlola imininingwane yezobuchwepheshe yemishini yokucubungula ukhonkolo ongaphansi kwamanzi kanye nemishini yokukhipha umoya.
Iphansi lethangi le-asphalt yokugcina ithangi lepayipi liyakhishwa epayipini lokudonsa amanzi, futhi amanzi angcolile akhishelwa ethangini elingenalutho noma ezinye iziqukathi nge-inlet kanye ne-outlet kanye nepayipi lokuzidonsa. Vula imbobo yase-Shenzhen epayipini lokumunca lepulasitiki bese uvula umgodi wase-Shenzhen nge-asbestos ukuze unciphise ukuchithwa kukawoyela negesi. Lapho umpompa uwoyela ongezansi ngesandla, kufanele kusetshenziswe abantu ababili ukuze kuthuthukiswe ukusebenza kahle kwabasebenzi futhi kuthunyelwe ithangi likaphethiloli ukuthi ligadwe.
Indlela yangaphakathi yokuxuba iwukuba kuqala wengeze ipulasitiki, ama-polymers afana nepulasitiki nezinye izilungisi ku-asphalt eguquliwe e-emulsified eshisayo. I-tank asphalt yenjoloba ibekwe ngemuva kokuxuba futhi i-polymer ehambisanayo kanye ne-asphalt e-emulsified eguquliwe ivezwe emonakalweni ukuze kutholwe i-polymer modified asphalt. Ithangi le-asphalt lenjoloba libe selilungiswa ngobuchwepheshe be-emulsion ukwenza i-asphalt moisturizing emulsion eguquliwe. I-polymer evame ukusetshenziswa endleleni yokuxuba yangaphakathi yi-SBS.
Uma ithangi le-asphalt yenjoloba lixutshwe bese livala ihora, hlanza ithangi lokuxuba, ungeze amanzi ahlanzekile, futhi uhlanze udaka lukasimende. Okulandelayo, hlanza amanzi. Khumbula ukuthi akumele kube namanzi ebhakedeni ukuvimbela ifomula ukuthi ingashintshi, ngisho newebhusayithi nezinye izinqubo zingagqwali. Enqubweni yokusebenzisa ithangi le-asphalt yenjoloba, wonke umuntu kufanele anake izinqubo eziningi ezincane ukuze agweme ukulimala okungadingekile ekusebenzeni.
Umehluko wokumelana nendawo phakathi kwethangi le-asphalt lenjoloba namanzi uyamangaza, futhi akulula ukuhlakazeka komunye nomunye ekamelweni lokushisa noma izinga lokushisa eliphezulu. Umkhiqizi wethangi le-asphalt Lapho umshini wesitshalo sokugcina i-asphalt yerabha ungaphansi kwemiphumela yethangi le-asphalt yokugcina i-asphalt centrifugal, ukugunda kwevidiyo, kanye nemishini yomthelela, umshini wethangi lokugcina itiyela lenjoloba uwenza ube yizinhlayiyana ezinosayizi wezinhlayiyana ongu-0.1~5μm, futhi isakazeke endaweni yamanzi equkethe ama-surfactants, ukuze i-demulsifier iqondiswe ekukhangiseni ebusweni bezinhlayiya ze-asphalt eguquliwe e-emulsified.
Ngakho-ke isitshalo sokugcina i-asphalt se-asphalt sinciphisa ukungezwani okungaphezulu phakathi kwamanzi kanye ne-asphalt e-emulsified eguquliwe, ukuze izinhlayiya ze-asphalt eziguquliwe zingakha uhlelo oluzinzile lokuhlakazeka emanzini, kanye nemishini yokutshala i-asphalt yokugcina i-rubber i-emulsion yamafutha emanzini. Isistimu yokusabalalisa enjalo insundu, ene-asphalt e-emulsified eguquliwe njengendlela yokusabalalisa kanye namanzi njengesigaba sesibili, futhi ingaba nomsebenzi omuhle ekamelweni lokushisa.
Ngomqondo othile, okokusebenza kwesitshalo se-asphalt sokugcina itiyela kungamanzi okuhlambulula itiyela eliguquliwe le-emulsified, ngaleyo ndlela lilawula umsebenzi wetiyela eliguquliwe.
Isitshalo se-asphalt sokugcina i-asphalt sincibilikisa i-asphalt yesiko le-asphalt eguquliwe, siyisakaze esixazululweni esiqukethe ama-antioxidants anezinhlayiya ze-asphalt eziguquliwe eziguquliwe ngokusebenzisa imishini ukwenza iphrofayili ye-asphalt aluminium eguquliwe. Ithangi le-asphalt yokugcina ithangi le-asphalt likasimende lesakhiwo se-flat ballastless track yamukela isitshalo se-cationic rubber asphalt yokugcina, ngoba i-polymer ivame ukusetshenziselwa ukuguqula i-asphalt ukuze kuthuthukiswe ukunwebeka nokuqina kwethangi le-asphalt yokugcina ithangi likasimende.
