Namuhla, i-asphalt pavement isetshenziswa kabanzi ekwakhiweni komgwaqo ngenxa yezinzuzo zayo eziningi. Njengamanje, sisebenzisa kakhulu itiyela elishisayo kanye netiyela elifakwe emulsified ekwakheni i-asphalt pavement. Ibitumeni elishisayo lidla amandla amaningi okushisa, ikakhulukazi inani elikhulu lesihlabathi namatshe adinga ukushisa okubhaka. Isimo sokwakha sabasebenzi sibi futhi umfutho wabasebenzi uphezulu. Uma usebenzisa i-emulsified bitumen ekwakheni, ukufudumeza akudingeki futhi kungafuthwa noma kuxutshwe ukuze kugandaywe ekamelweni lokushisa, futhi umgwaqo wezakhiwo ezihlukahlukene ungagandaywa. Ngaphezu kwalokho, itiyela elakhiwe nge-emulsified lingageleza lodwa ekamelweni lokushisa, futhi lingenziwa libe yitiyela elifakwe emulsified lokugxila okuhlukene njengoba kudingeka. Kulula ukufeza ukushuba kwefilimu ye-asphalt edingekayo ngokuthululela noma ukugqobhoza ungqimba, olungenakufinyelelwa nge-bitumen eshisayo. Ngokuthuthukiswa kancane kancane koxhaxha lwemigwaqo kanye nezidingo zokuthuthukiswa kwemigwaqo yezinga eliphansi, ukusetshenziswa kwebitumen emulsified kuzoba kukhulu futhi kukhudlwana; ngokuthuthukiswa kokuqwashisa ngemvelo kanye nokushoda kwamandla kancane kancane, ingxenye yetiyela efakwe emulsified ku-asphalt izokhula ngokuya phezulu. Ububanzi bokusetshenziswa buzoba banzi futhi bube banzi, futhi ikhwalithi izoba ngcono futhi ibe ngcono. Ibitumen e-emulsified inezici zokungenabuthi, ezingenaphunga, ezingashi, zome ngokushesha kanye nokubopha okuqinile. Awukwazi nje ukuthuthukisa ikhwalithi yomgwaqo, ukwandisa ububanzi bokusetshenziswa kwe-asphalt, ukunweba inkathi yokwakha, ukunciphisa ukungcoliswa kwemvelo nokuthuthukisa izimo zokwakha, kodwa futhi konga amandla nezinto zokwakha.
Ibitumen e-emulsified ikakhulukazi yakhiwe ngetiyela, i-emulsifier, isinzisi namanzi.
1. Ibitumen iyinsimbi eyinhloko yebitumen e-emulsified. Izinga le-asphalt lihlobene ngokuqondile nokusebenza kwe-asphalt e-emulsified.
2. I-Emulsifier iyinto eyinhloko ekubunjweni kwe-asphalt e-emulsified, enquma ikhwalithi ye-asphalt e-emulsified.
3. I-stabilizer ingenza i-asphalt e-emulsified ibe nokuzinza okuhle kwesitoreji ngesikhathi senqubo yokwakha.
4. Ngokuvamile kuyadingeka ukuthi izinga lamanzi akumele libe lukhuni kakhulu futhi akufanele liqukathe okunye ukungcola. Inani le-pH lamanzi ne-calcium ne-magnesium plasma linomthelela emulsification.
Ngokuya ngezinto zokwakha kanye nama-emulsifiers asetshenzisiwe, ukusebenza nokusetshenziswa kwe-asphalt e-emulsified nakho kuhlukile. Okuvame ukusetshenziswa yilezi: itiyela elenziwe nge-emulsified elivamile, i-asphalt ye-emulsified ye-SBS eshintshiwe, i-asphalt e-emulsified ye-SBR eshintshiwe, i-asphalt e-emulsified eqhekeka kancane kancane, i-asphalt e-emulsified evumela ukungena okuphezulu, ukugxila okuphezulu Itiyela le-viscosity emulsified. Ekwakhiweni nasekugcinweni kwe-asphalt pavement, i-asphalt e-emulsified efanelekile ingakhethwa ngokuvumelana nezimo zomgwaqo kanye nezakhiwo.
