Kwa microsurfacing, chiŵerengero chilichonse chosakanikirana chomwe chimapangidwa ndikuyesa kogwirizana, komwe kumakhudzidwa ndi mitundu ingapo monga emulsified asphalt ndi aggregate type, aggregate gradation, madzi ndi emulsified asphalt kuchuluka, ndi mitundu ya mineral fillers ndi zowonjezera. . Chifukwa chake, kusanthula kwa kuyesa kwapatsamba kwa zitsanzo za labotale pansi pamikhalidwe ina ya uinjiniya kwakhala chinsinsi chowunikira magwiridwe antchito a ma micro-surface osakaniza. Mayeso angapo omwe amagwiritsidwa ntchito kwambiri amayambitsidwa motere:
1. Kusakaniza mayeso
Cholinga chachikulu cha mayeso osakaniza ndikufanizira malo omangapo opangira. Kugwirizana kwa emulsified asphalt ndi aggregates kumatsimikiziridwa kudzera mu mawonekedwe owuma a yaying'ono pamwamba, ndipo nthawi yeniyeni komanso yolondola yosakanikirana imapezeka. Ngati nthawi yosakanikirana ndi yayitali kwambiri, msewu wamtunda sudzafika ku mphamvu zoyamba ndipo sudzatsegulidwa kwa magalimoto; ngati nthawi yosakaniza ndi yochepa kwambiri, kupanga mapangidwe sikudzakhala kosalala. Zomangamanga za micro-surfacing zimakhudzidwa mosavuta ndi chilengedwe. Choncho, popanga kusakaniza, nthawi yosakaniza iyenera kuyesedwa pansi pa kutentha koyipa komwe kungachitike panthawi yomanga. Kupyolera mu mayesero angapo a machitidwe, zinthu zomwe zimakhudza kaphatikizidwe ka micro-surface zimawunikidwa lonse. Zotsatira zomwe zaperekedwa ndi izi: 1. Kutentha, kutentha kwapamwamba kumatha kuchepetsa kwambiri nthawi yosakaniza; 2. Emulsifier, mlingo waukulu wa emulsifier, utalikirapo nthawi yosakaniza; 3. Simenti, kuwonjezera simenti akhoza kuwonjezera kapena kufupikitsa osakaniza. Nthawi yosakaniza imatsimikiziridwa ndi katundu wa emulsifier. Nthawi zambiri, kuchuluka kwachulukidwe, kumachepetsa nthawi yosakaniza. 4. Kuchuluka kwa madzi osakaniza, kuwonjezereka kwa madzi osakaniza, ndi nthawi yayitali yosakaniza. 5. Phindu la pH la yankho la sopo nthawi zambiri ndi 4-5 ndipo nthawi yosakaniza ndi yaitali. 6. Kuchuluka kwa zeta kwa phula lopangidwa ndi emulsified ndi mapangidwe awiri a magetsi a magetsi a emulsifier, nthawi yayitali yosakaniza.
2. Kuyesa kumamatira
Makamaka amayesa mphamvu yoyambirira ya yaying'ono pamwamba, yomwe imatha kuyeza molondola nthawi yoyambira. Kukwanira kokwanira koyambirira ndikofunikira kuti mutsimikizire nthawi yotsegulira magalimoto. Mndandanda wa adhesion uyenera kuwunikiridwa mozama, ndipo mtengo wokhazikika woyezera uyenera kuphatikizidwa ndi kuwonongeka kwachitsanzo kuti mudziwe nthawi yoyambira komanso nthawi yotseguka yamagalimoto osakaniza.
3. Yet wheel wear test test
Kuyesa kwa magudumu onyowa kumatengera kuthekera kwa msewu kukana kuvala matayala pakanyowa.
Kuyesa kwa ola limodzi konyowa kwa magudumu kumatha kudziwa kukana kwa abrasion kwa wosanjikiza wa microsurface komanso mawonekedwe opaka a asphalt ndi kuphatikiza. Kulimbana ndi kuwonongeka kwa madzi kwa micro-surface modified emulsified asphalt kusakaniza kumayimiridwa ndi 6-day kuvala mtengo, ndipo kukokoloka kwa madzi kwa osakaniza kumawunikidwa kupyolera mu ndondomeko yayitali. Komabe, kuwonongeka kwa madzi sikumangowonekera m'malo mwa phula la asphalt, komanso kusintha kwa gawo la madzi kungayambitse kuwonongeka kwa kusakaniza. Kuyeza kwa masiku 6 kumiza kwa abrasion sikunaganizire momwe madzi amaundana pamiyala m'malo oundana. The chisanu kukweza ndi peeling zotsatira chifukwa phula filimu pamwamba pa zinthu. Chifukwa chake, kutengera kuyesa kwamasiku 6 kumiza m'madzi kwa magudumu onyowa, akukonzekera kuyesa kuyesa kwa ma wheel abrasion kuti awonetsere bwino zotsatira zoyipa za madzi pakusakaniza kwapamtunda.
4. Rutting deformation test
Kupyolera mu kuyesa kwa rutting deformation, kuchuluka kwa ma wheel track wide deformation kumatha kupezedwa, ndipo mphamvu yotsutsa-rutting ya osakaniza a micro-surface imatha kuwunikiridwa. Zing'onozing'ono m'lifupi mapindikidwe mlingo, mphamvu mphamvu kukana mapindikidwe rutting ndi bwino kutentha bata; M'malo mwake, mphamvu yolimbana ndi rutting deformation. Kafukufukuyu adapeza kuti kuchuluka kwa ma wheel track wide deformation kumagwirizana bwino ndi emulsified asphalt. Kuchuluka kwa emulsified asphalt kumapangitsanso kukana kwamphamvu kwa micro-surface kusakaniza. Ananenanso kuti izi ndichifukwa choti phula la polymer emulsified litaphatikizidwa mu binder yopangidwa ndi simenti, zotanuka modulus ya polima ndi yotsika kwambiri kuposa simenti. Pambuyo pawiri anachita, katundu wa cementitious zakuthupi kusintha, chifukwa mu kuchepetsa kuuma wonse. Zotsatira zake, kusinthika kwa magudumu kumawonjezeka. Kuphatikiza pa mayeso omwe ali pamwambawa, mayeso osiyanasiyana amayenera kukhazikitsidwa molingana ndi mikhalidwe yosiyanasiyana ndipo mayeso osakanikirana akuyenera kugwiritsidwa ntchito. Pomanga kwenikweni, chiŵerengero chosakaniza, makamaka kumwa madzi osakaniza ndi kugwiritsa ntchito simenti, kungasinthidwe moyenera malinga ndi nyengo ndi kutentha kosiyana.
Kutsiliza: Monga ukadaulo wodzitetezera, kuyang'ana kwapang'onopang'ono kumatha kupititsa patsogolo magwiridwe antchito am'misewu ndikuchotsa bwino matenda osiyanasiyana panjira. Panthawi imodzimodziyo, imakhala ndi mtengo wotsika, nthawi yochepa yomanga komanso kukonza bwino. Nkhaniyi ikuwunikanso kaphatikizidwe ka ma micro-surfacing osakanikirana, kusanthula momwe amakhudzira chonsecho, ndipo ikuwonetsa mwachidule ndikuwunikira mayeso a magwiridwe antchito a ma micro-surfacing osakanikirana momwe alili pano, omwe ali ndi tanthauzo labwino pakufufuza mozama kwamtsogolo.
Ngakhale ukadaulo wa micro-surfacing wakula kwambiri, uyenera kufufuzidwanso ndikukonzedwa kuti upititse patsogolo luso laukadaulo kuti uthandizire bwino komanso kupititsa patsogolo magwiridwe antchito amisewu yayikulu ndikukwaniritsa zosowa zamagalimoto. Kuonjezera apo, panthawi yomanga ma micro-surfacing, zinthu zambiri zakunja zimakhudza kwambiri ubwino wa polojekitiyo. Chifukwa chake, zomanga zenizeni ziyenera kuganiziridwa ndipo njira zowongolera zasayansi ziyenera kusankhidwa kuti zitsimikizire kuti zomangamanga zazing'ono zitha kukhazikitsidwa bwino ndikukwaniritsa Kuwongolera magwiridwe antchito.
