Izinto okufanele uzihlole ukuze uthole imishini ye-asphalt e-emulsified
I-Sinoroader emulsified asphalt pavement engineering imishini evamile, manje isisetshenziswe kabanzi kancane kancane.
Sonke siyazi ukuthi ngaphambi kokuba kusetshenziswe noma iyiphi into, impahla kufanele ihlolwe kuqala ukuze kubhekwe ukuthi ukufakwa kwayo kujwayelekile yini, bese iqala ukusetshenziswa. Ukusetshenziswa kwemishini yokukhiqiza itiyela eshintshiwe eguquliwe nakho kunganweba isizini ephezulu. Umshini we-asphalt oguquliwe kanye nomshini wamanzi wamatshe ungahlanganiswa netshe elimanzi ukuze wenze ifilimu eqhubekayo ngaphansi kwezimo ezingaphezulu kwezinga lokushisa eliphansi le-asphalt netshe. I-viscosity ye-asphalt iphansi futhi i-viscosity ye-asphalt emulsified iphansi. Ifilimu emanzi ngaphansi kwama-degree angu-10.
Hlola umshini oguquliwe we-emulsified asphalt umshini wokuguqula. Uma umshini we-emulsion emulsified asphalt colloid emulsion usetshenziswa isikhathi eside, umshini wokugaya uzoba mkhulu, ngakho kulokhu sidinga ukuwulungisa ukuze siqhubeke nokukhiqiza. Lena inkinga elula uma kuqhathaniswa. Ukuze kuhlaziywe isilungisi, inani elijwayelekile lesilungisi elengeziwe kufanele lilungiswe ngokuya ngekhwalithi yamanzi ehlukile lapho kwengezwa inani le-pH. Inkinga idinga ukucutshungulwa ngochwepheshe. Imishini yokuguqula i-asphalt ngokwayo iyinkinga engenzeka, ngoba i-asphalt evamile nayo inezigaba ezahlukene. Lapho ukhiqiza i-asphalt eguquliwe, kufanele kuqashelwe isidingo sezinto ezingavuthiwe, okuyi-asphalt nekhwalithi evamile.
Izinto okufanele zihlolwe ukuze kusetshenziswe imishini ye-asphalt eshintshiwe ngesikhathi sokuhlolwa. Kufanele sisebenze ngendlela efanele ngokwemiyalelo. Kungale ndlela kuphela lapho singathola khona imiphumela engcono. Uma ungaqondi lutho, sicela ukhululeke ukuxhumana nathi kusenesikhathi.
