Ukuvalwa kwe-slurry kusebenzisa okomshini ukuze kuxube itiyela efakwe ngokwezinga elifanele, i-asphalt eqinile necolekile, amanzi, izigcwalisi (usimende, umcako, umlotha wempukane, impushana yetshe, njll.) kanye nezithasiselo ngokwesilinganiso esiklanyelwe zibe yingxube ye-slurry futhi igandaywe ngendlela efanayo. emgwaqeni wokuqala futhi ihlanganiswe ngokuqinile nomgwaqo wokuqala ngokusebenzisa izinqubo zokumboza, ukukhishwa kwe-demulsification, ukuhlukaniswa kwamanzi, ukuhwamuka nokuqina ukuze kwakhiwe uphawu oluminyene, oluqinile, olungagugi kanye nomgwaqo, okuthuthukisa kakhulu ukusebenza komgwaqo. indawo yomgwaqo.
Ubuchwepheshe bokuvalwa kwe-slurry bavela eJalimane ngasekupheleni kwawo-1940. E-United States, ukusetshenziswa kwe-slurry sealant kwenza ama-60% omgwaqo omnyama wezwe, futhi ububanzi bayo bokusetshenziswa bandisiwe. Idlala indima ekuvimbeleni nasekulungiseni izifo ezinjengokuguga, imifantu, ukushelela, ukuxega, kanye nemigodi emigwaqweni egandayiwe emigwaqweni emisha nendala, okwenza Izakhiwo zomgwaqo ezingangeni emanzini, ezilwa nokushushuluza, ezibushelelezi nezingagugi zithuthukiswa ngokushesha.
Ukuvalwa kwe-slurry kuyindlela yokwakha evikelayo yokwelashwa kwendawo egandaywe ngamatshe. Imigwaqo emidala yetiyela ngokuvamile inemifantu nemigodi. Lapho ubuso bugqokile, ingxube ye-asphalt slurry sealing emulsified isakazwa endaweni egandayiwe ibe ungqimba oluncane futhi ivunyelwe ukuba iqine ngokushesha ngangokunokwenzeka, ukuze umgwaqo ogandaywe we-asphalt ugcinwe. Iwukunakekela nokulungiswa ngenhloso yokubuyisela ukusebenza kwendawo yomgwaqo nokuvimbela umonakalo owengeziwe.

Ukuqhekeka okuhamba kancane noma okuphakathi nendawo okuxubene kwe-asphalt e-emulsified esetshenziswa kungqimba lwe-slurry seal kudinga okuqukethwe kwetiyela noma i-polymer asphalt cishe ku-60%, futhi ubuncane akumele bube ngaphansi kuka-55%. Ngokuvamile, i-asphalt ye-anionic emulsified ayinakunamathela kahle ezintweni zamaminerali futhi ithatha isikhathi eside ukwakha. Isetshenziswa kakhulu kuma-alkaline aggregates, 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 kwe-Class II nangaphansi kwemigwaqo emikhulu, futhi ifaneleka ungqimba oluphansi lophawu, ukugqoka ungqimba noma ungqimba oluvikelayo lwemigwaqo emikhulu emisha. Manje isisetshenziswa nasemigwaqweni emikhulu.
Ukuhlukaniswa kwama-slurry seal:
Ngokusho kwe-mineral gradation
Ngokuya ngezigaba ezihlukene zezinto zamaminerali, ungqimba lokuvalwa kwe-slurry lungahlukaniswa lube ungqimba oluhle lokuvala, ungqimba oluphakathi lokuvala kanye nongqimba olumahhadla lokuvala, olumelwe yi-ES-1, ES-2 kanye ne-ES-3 ngokulandelana.
Ngokwejubane lokuvuleka kwezimoto
Ngokuya ngesivinini sokuvula ithrafikhi[1], ama-slurry seal angahlukaniswa ngokuvula okusheshayo kwethrafikhi slurry seal kanye nokuvula kancane kwethrafikhi slurry seals.
Ihlukaniswe ngokuya ngokuthi ama-modifiers e-polymer ayengeziwe
Ngokuya ngokuthi i-polymer modifier yengeziwe yini, ungqimba lokuvalwa kwe-slurry lungahlukaniswa lube isendlalelo sokuvalwa kwe-slurry kanye nosendlalelo sokutywinwa esilungisiwe.
Ihlukaniswe ngokusho kwezakhiwo ezahlukene ze-asphalt emulsified
Isendlalelo sokuvala uphawu se-slurry sihlukaniswe ungqimba olujwayelekile lokuvala oludakayo kanye nongqimba oluguquliwe lokuvala uphawu ngokuya ngezakhiwo ezahlukahlukene ze-asphalt e-emulsified.
Ihlukaniswe ngokujiya
Ngokusho kogqinsi oluhlukene, ihlukaniswe yaba ungqimba oluhle lokuvala (ungqimba lwe-I), ungqimba lokuvala oluphakathi nendawo (uhlobo lwe-II), ungqimba oluqinile lokuvala (uhlobo lwe-III) kanye nongqimba oluwugqinsi lokuvala (uhlobo lwe-IV).
