Emulsified asphalt imagwiritsidwa ntchito makamaka pakukweza ndi kukonza misewu, monga miyala ya chip seal, ndipo pali ntchito zambiri zapadera zomwe sizingasinthidwe ndi zida zina za phula, monga kusakaniza kozizira ndi chisindikizo cha slurry. Emulsified asphalt itha kugwiritsidwanso ntchito popanga misewu yatsopano, monga mafuta a tack coat ndi mafuta olowera.

Kodi mawonekedwe amtundu wa Gaoyuan emulsified asphalt ndi ati:
1. Kumanga kozizira ndikopulumutsa mphamvu, kuchepetsa kugwiritsira ntchito, kotetezeka, kusamala zachilengedwe, komanso kuchepetsedwa pang'ono ndi nyengo.
3. Mapangidwe osiyanasiyana opangira misewu, kukonza ndi kukonza.
4. N'zosavuta kulamulira khalidwe la kufalikira, ali ndi luso lolowera bwino ndi kumamatira, ndipo amatha kusintha bwino misewu.
5. Zimapewa kutenthedwa mobwerezabwereza ndikuchepetsa kutaya kwa asphalt khalidwe.
Emulsified asphalt imagawidwa kukhala cationic emulsified asphalt ndi anionic emulsified asphalt. Tinthu tating'onoting'ono ta cationic emulsified asphalt timayimbidwa bwino, ndipo tinthu tating'ono ta anionic emulsified asphalt ndi zoyipa. Pamene cationic emulsified asphalt amalumikizana pamwamba pa aggregate, chifukwa cha milandu yosiyanasiyana, zotsutsana zimakopana. Pamaso pa filimu yamadzi, tinthu tating'onoting'ono ta asphalt titha kukulungidwa pamwamba pazophatikizira ndipo zimatha kutsatiridwa bwino ndikuphatikizidwa. Chifukwa chake, imatha kumangidwabe m'malo achinyezi komanso otsika (pamwamba pa 5 ° C). Komabe, asphalt ya anionic emulsified ndi yosiyana. Imakhala ndi mlandu woyipa pamwamba pa zonyowa, zomwe zimawapangitsa kuti azithamangitsana. Asphalt particles sangathe kumamatira pamwamba pa aggregate mwamsanga. Ngati phula particles kuti wokutidwa pamwamba pa akaphatikiza, madzi mu emulsion ayenera chamunthuyo. Choncho, n'kovuta kumanga mu nyengo yonyowa kapena yotsika kutentha.
Pamene emulsified asphalt imasweka ndikukhazikika - imachepetsedwa kukhala phula losalekeza ndipo madzi amachotsedwa kwathunthu, ndipo mphamvu yomaliza ya zinthu zamsewu imatha kupangidwa.
Kusinthidwa emulsified asphalt ndi phula lamadzimadzi lopangidwa ndi phula ndi emulsifier pansi pa njira zina ndi latex. Kusiyana pakati pa asphalt yosinthidwa emulsified ndi emulsified asphalt ndikuti latex imawonjezeredwa panthawi yopanga.
Khola emulsion akamagwira uniformly dispersing phula particles mu amadzimadzi njira munali emulsifier.
Udindo wa Gaoyuan mtundu wa cationic emulsified asphalt:
Emulsified asphalt imagwiritsidwa ntchito makamaka pakukweza ndi kukonza misewu, monga miyala ya chip seal, ndipo pali ntchito zambiri zapadera zomwe sizingasinthidwe ndi zida zina za phula, monga kusakaniza kozizira ndi chisindikizo cha slurry. Emulsified asphalt itha kugwiritsidwanso ntchito pomanga misewu yatsopano, monga mafuta opaka malaya, mafuta olowa, etc.
