I-slurry seal iwukusebenzisa imishini yokuhlanganisa i-asphalt efakwe ngokwezinga elifanele, i-asphalt eqinile necolekile, amanzi, izigcwalisi (usimende, umcako, umlotha womlotha, impuphu yetshe, njll.) kanye nezithasiselo zibe ingxube ye-slurry ngokwesilinganiso esiklanyelwe futhi isakazwe ngokulinganayo. it emgwaqeni wokuqala. Ngemuva kokugoqa, ukukhishwa kwe-demulsification, ukuhlukaniswa kwamanzi, ukuhwamuka nokuqina, kuhlanganiswe ngokuqinile nomgwaqo wokuqala ukuze kwakhiwe uphawu oluqinile, oluqinile, olungagugi kanye nomgwaqo, okuthuthukisa kakhulu ukusebenza komgwaqo.
Ubuchwepheshe be-slurry seal bavela eJalimane ngasekupheleni kwawo-1940. E-United States, ukusetshenziswa kwe-slurry seal kwenza u-60% wezindawo ezimnyama zemigwaqo yezwe, futhi ububanzi bayo bokusetshenziswa bandisiwe. Ibamba iqhaza ekuvimbeleni nasekulungiseni izifo ezinjengokuguga, imifantu, ubushelelezi, ukuxega, kanye nemigodi emisha nendala, okwenza umgwaqo ungangeni emanzini, ovimbela ukushibilika, oyisicaba, futhi ongagugi uthuthuke ngokushesha.

I-slurry seal nayo iyindlela yokwakha evikelayo yokulungisa indawo egandaywe ngamatshe. Imigwaqo emidala yetiyela ngokuvamile inemifantu nemigodi. Lapho ubuso bugqokile, ingxube ye-asphalt slurry seal emulsified isakazwa ibe ungqimba oluncane endaweni egandaywe ngamatshe futhi iqiniswe ngokushesha ngangokunokwenzeka ukuze kugcinwe umgwaqo ogandaywe yi-asphalt ukhonkolo. Iwukulungisa kanye nokulungisa okuhloswe ngayo ukubuyisela ukusebenza kwendlela egandayiwe ukuze kuvinjwe omunye umonakalo.
Itiyela elixutshwe ne-slurry emulsified elixutshwe ne-slow-crack noma eliphakathi nendawo lidinga i-asphalt noma i-polymer asphalt okuqukethwe okungaba ngu-60%, futhi ubuncane akumele bube ngaphansi kuka-55%. Ngokuvamile, i-asphalt ye-anionic emulsified ayinakunamathela kahle ezintweni ezimbiwa phansi kanye nesikhathi eside sokubumba, futhi isetshenziswa kakhulu ekuhlanganiseni kwe-alkaline, njenge-limestone. I-Cationic emulsified asphalt inokunamathela okuhle kuma-acidic aggregates futhi isetshenziswa kakhulu kuma-acidic aggregates, njenge-basalt, granite, njll.
Ukukhethwa kwe-asphalt emulsifier, enye yezithako ku-asphalt e-emulsified, kubaluleke kakhulu. I-asphalt emulsifier enhle ayikwazi ukuqinisekisa kuphela ikhwalithi yokwakha kodwa futhi yonga izindleko. Lapho ukhetha, ungabheka izinkomba ezihlukahlukene ze-asphalt emulsifiers kanye nemiyalelo yokusetshenziswa kwemikhiqizo ehambisanayo. Inkampani yethu ikhiqiza izinhlobonhlobo zama-asphalt emulsifiers anezinjongo eziningi. Uma unemibuzo, sicela uxhumane nesevisi yethu yamakhasimende.
I-Emulsified asphalt slurry seal ingasetshenziselwa ukugcinwa kokuvimbela imigwaqo emikhulu nephansi, futhi ifanele uphawu oluphansi, isendlalelo sokugqoka noma ungqimba oluvikelayo lwemigwaqo emikhulu esanda kwakhiwa. Manje isisetshenziswa nasemigwaqweni emikhulu.
Ukuhlukaniswa kwe-slurry seal:
Ngokokuhlukaniswa okuhlukile kwezinto zamaminerali, uphawu lwe-slurry lungahlukaniswa lube uphawu oluhle, uphawu oluphakathi nendawo kanye ne-coarse seal, emelwe yi-ES-1, ES-2 kanye ne-ES-3 ngokulandelanayo.
Ngokusho kwejubane lokuvula ithrafikhi
Ngokuya ngesivinini sokuvula ithrafikhi [1], uphawu oludakayo lungahlukaniswa lube ukuvuleka okusheshayo kwethrafikhi uhlobo lwe-slurry seal kanye nokuvulwa kancane kwethrafikhi uhlobo lwe-slurry seal.
Ngokusho kokuthi ama-modifiers e-polymer ayengeziwe
Ngokuya ngokuthi ama-modifiers e-polymer ayengeziwe yini, uphawu lwe-slurry lungahlukaniswa lube seal slurry kanye ne-modified slurry seal.
Ngokusho kwezakhiwo ezahlukene ze-asphalt emulsified
Ngokwezakhiwo ezihlukene ze-asphalt e-emulsified, uphawu lwe-slurry lungahlukaniswa lube uphawu olujwayelekile lwe-slurry kanye ne-modified slurry seal.
Ngokobukhulu, ingahlukaniswa ibe ungqimba oluhle lokuvala (ungqimba I), ungqimba lokuvala olumaphakathi (uhlobo II), ungqimba olumahhadla lokuvala (uhlobo III) kanye nongqimba oluqinile lokuvala (uhlobo IV).
