Kunezindlela ezimbili eziyinhloko zokuguqula amathangi e-asphalt kawoyela oshisayo: indlela yokuxuba yangaphandle kanye nendlela yokuxuba yangaphakathi. Indlela yokuxuba yangaphandle iwukuqala ngokulungisa ithangi le-asphalt likawoyela oshisayo, bese wengeza isilungisi se-polymer latex ethangini le-asphalt likawoyela oshisayo we-Jiangxi, bese uxuba futhi ugoqe ukuze ulenze. I-emulsion ye-polymer ngokuvamile i-CR emulsion, i-emulsion ye-SBR, i-emulsion ye-acrylic, njll. Indlela yokuxuba yangaphakathi iwukuqala ukuxuba irabha, ipulasitiki nezinye izithasiselo nezinye izithasiselo zibe itiyela elishisayo, bese uzixuba ngokulinganayo futhi ubangele ukuxhumana okudingekayo phakathi kwe-polymer ne-asphalt ukuze uthole i-asphalt eguquliwe nge-polymer, bese udlulela inqubo ye-emulsification. Ukukhiqiza i-emulsion ye-asphalt eguquliwe, i-polymer evame ukusetshenziswa endleleni yokuxuba yangaphakathi yi-SBS. Uma i-asphalt impahla inyakaziswa futhi imisiwe isikhathi esifanayo, sula ubuso bomgqomo onyakazayo, engeza amanzi acacile, bese uhlanza udaka. Bese ushanela amanzi, ukhumbula ukuthi akufanele kube khona ukunqwabelana kwamanzi ebhakedeni ukuze uvimbele ifomula ukuba ibangele izinguquko, noma ngisho nezinyathelo ezifana nesiteshi ukubangela ukugqwala. Ngesikhathi sokusetshenziswa, wonke umuntu kufanele anake izinyathelo eziningi ezincane ukuze agweme ukushelela okungadingekile ekusebenzeni komshini.

Isipiliyoni sokusebenza kwethangi le-asphalt lamafutha ashisayo:
Ukungezwani okungaphezulu kwamathangi e-asphalt kawoyela oshisayo namanzi kuhluke kakhulu, futhi awahlangani emazingeni okushisa ajwayelekile noma aphezulu. Lapho umshini we-asphalt wamafutha oshisayo ungaphansi kwemiphumela yemishini efana ne-centrifugation esheshayo, ukugunda, kanye nomthelela, umshini we-asphalt wamafutha oshisayo uwuphendulela ube yizinhlayiya ezinobukhulu bezinhlayiyana ze-0.1 ~ 5 μm, futhi uhlakazeke zibe yizinhlayiya ezinama-surfactants ( emulsifiers-stabilizers) Emkhathini wamanzi, ngenxa yokuthi i-emulsifier ingakhangiswa ngendlela eqondile ebusweni bezinhlayiya zemishini ye-asphalt ye-asphalt e-Jiangxi, inciphisa ukungezwani kobuso phakathi kwamanzi netiyela, okuvumela izinhlayiya zetiyela ukuba zakhe uhlelo oluzinzile oluhlakazekile emanzini. Umshini oshisayo wethangi le-asphalt uwoyela emanzini. ukwakheka kwe-emulsion. Isimiso esihlakazekile esinjalo sinombala onsundu, sinetiyela njengesigaba esihlakazekile namanzi njengesigaba esiqhubekayo, futhi sijabulela uketshezi oluphakeme ekushiseni kwegumbi. Ngomqondo othile, umshini wethangi likawoyela we-asphalt oshisayo usebenzisa amanzi ukuze "uhlambulule" itiyela, ngakho uketshezi lwetiyela luyalungiswa.
Ithangi le-asphalt lamafutha ashisayo lenziwa ngokushisa-ukuncibilika kwe-asphalt eyisisekelo kanye nokuhlakaza izinhlayiya ze-asphalt zokukhanya ngomshini kusisombululo esinamanzi esiqukethe i-emulsifier ukuze kwakhiwe i-asphalt ewuketshezi. Ithangi le-asphalt likawoyela oshisayo elishisayo elisetshenziswa esakhiweni sokwakhiwa kwe-slab ballastless lisebenzisa ithangi le-asphalt likawoyela oshisayo. Ngenxa yokuguquguquka nokuqina kwethangi le-asphalt likawoyela oshisayo, ama-polymers avame ukusetshenziselwa ukuguqula itiyela.
