I. Ubusobanuro bwa tekiniki hamwe nibyiza byingenzi
Umushinga wa Micro-Surfacing nuburyo bwo kubungabunga bushingiye ku kuzamura tekinoroji ya slurry. Iteka ryayo riri mu gukoresha polymer-yahinduwe ku isonga, ivanze n'amabuye, filers (nko mu mazi ya slurture yihariye, yakwirakwiriye ku butaka bw'umwimerere kugira ngo akore ikidodo kidasanzwe. Iri koranabuhanga rifite ibyiza bikurikira:

Kubaka byihuse no gufungura traffic
Kubaka ubushyuhe bwicyumba, ntibikenewe ibikoresho byubushyuhe, traffic irashobora gufungurwa mugihe cyamasaha 2, kugabanya cyane igihe cyumuhanda.
Birakwiriye mumihanda minini ifite amajwi manini, kandi toni 500 yo kuvanga irashobora gukwirakwira kumunsi, hamwe nuburyo bwubwubatsi burenze kure gakondo gakondo bishyushye-kuvanga inzira ya Asfalt.
Kunoza imikorere
Kurwanya skid: Ubujyakuzimu bwa macro butera imbere, ubufatanye bwo guterana imbere bwiyongereye, kandi ikibazo cyo kunyerera hejuru yumuhanda utera imbere neza.
Amazi: Uburozi buke bwa 5% cyangwa buke, bukora igice kinini cyo kurwanya urugero kugirango wirinde amazi yo hejuru ajya hejuru yumuhanda.
Kuramba: Ubuzima bwa serivisi ni imyaka 5-8, hamwe n'imbaraga zifite ubujyakuzimu bwa ≤38mm birashobora gusanwa, bikatinda kurenga ku muhanda.
Kurengera ibidukikije n'ubukungu
Kubaka ubushyuhe busanzwe, nta mwotsi wuburozi numyuka ihumariyamoro, gukoresha ingufu bigabanuka kurenza 50%.
Igiciro ni 30%-munsi yumucyo kurenza icyaro gishyushye, kandi birashobora gukoreshwa muburyo butaziguye mugushiramo imihanda mishya kugirango ugabanye gukoresha amabuye ahenze.

2. Ikoranabuhanga ryo kubaka hamwe ningingo zingirakamaro
Gutegura hejuru yumuhanda wambere
Guvura RUT: ≤5m imbuts yahawe agaciro ka 1cm micro-surfacing; 5-20mm RUZuzuye mu bice bibiri; > 20m imbuts igomba gusya no gushyirwaho ikimenyetso mubice byinshi.
Guvurwa:> 5mm- 5mm hagomba gushyirwaho kashe; Gukuramo kandi ibinogo bigomba gucukurwa no kuzura mbere yo guhabwa.
Sura Gutanga:
Ibisabwa byoza: Koresha amazi meza cyangwa umuvuduko mwinshi wo gukaraba kugirango urebe ko nta mbaraga cyangwa kwirundanya amazi, no kubaka amazi nyuma yo gukama.
Ibikoresho no kuvanga igishushanyo
Igiteranyo: Koresha amabuye ya alkaline nka basalt na vabase, hamwe numucanga uhwanye ≥65% kugirango umenye ko amphesion hamwe na asfalt.
Imenyekana Asfalt: igomba kuba Polymer yahinduwe (nka SBR, SBS), hamwe nuburyo bworoshye bwibisigisigi ni ≥57 ℃.
Fililer: sima ikundwa, kandi dosage igenwa nikizamini, ishobora guhindura igihe cyo kuvanga nimbaraga zimbaraga zivanze.
Igishushanyo cya Gradation: Koresha amanota ya III kugirango ugenzure ibikorwa byuruvange no guhuriza hamwe.
Gutanga no Gukora Igenzura
Gutanga ubunini: Hitamo ukurikije ingano yumuhanda (traffic nyinshi 10mm, hagati 7mm, urumuri 3-4mm).
Umuvuduko wo gutwara: 1.5-3.0km // kugumana umuvuduko umwe kugirango wirinde urupapuro rutemewe.
Gufata hamwe: ingingo za horizontal hejuru ya 4-5m, hamwe ningingo ndende ziherereye kumurongo wo kuranga kugirango urebe neza.
Ibisabwa ibikoresho: Koresha ikidodo gihoraho cya Slurry Cuver gifite inkono ya v-ingufu zifatika kugirango ugere ku kugabana bisanzwe.
Ibipimo byubwubatsi:
Kwitaho no Gufungura traffic
Kubungabunga kwambere: Irinde feri itunguranye no guhindukira nyuma yo guhatanira. Iyo 12.7mm umubyimba wikidodo kiri hejuru ya 24 ℃ kandi ubushuhe buri munsi ya 50%, birashobora kwihanganira ibinyabiziga bizunguruka mu isaha 1.
Gufungura byuzuye: Ukurikije ubushyuhe no gukiza imvange, ubusanzwe ibinyabiziga bikinguwe nyuma yamasaha 24.

III. Gusaba Ingaruka nibisanzwe
Gutezimbere Imikorere
Imikorere irwanya skid (Coefficient yo Gutesha agaciro) yanojwe na 30% -50%, kandi igipimo cyimpanuka kigabanuka kurenza 20%.
Urupapuro rwa kaburimbo rushingiye ku rubingo rukora munsi ya 50ml / min, gutinda neza kwangirika kw'amazi.
Nyuma yo guhagarikwa byuzuye, ikariso ya IRI agaciro karagabanutse munsi ya 1.5m / km, hamwe no guhumurizwa guterana ku buryo bugaragara.
Isesengura ryunganira mu bukungu
Nyuma ya micro-surfacing yakoreshejwe kumushinga wumuhanda, igiciro cyo gufatantu cyagabanutseho 40% mugihe cyimyaka 5, kandi ukwezi kwa kabiri kwaguwe nimyaka 3-5.
Ugereranije na ashyushye-ashyushye ashyushye, igiciro cyo gufata neza kuri kilometero cyagabanutseho na Yuan 200.000, hamwe nu myuka ihumanya ukabije kagarukiye kagabanutseho 60%.
Ibikorwa byakurikiwe
Ibice byo kumuhanda hamwe nijwi rinini ryumuhanda hamwe nigipimo kinini cyimodoka ziremereye.
Inzitizi zidahuye nkimpande nto, ruto, no gusaza bigaragara hejuru yumuhanda.
Imishinga yo kubungabunga byihutirwa isaba gusana kwihuta.
IV. Amahame ya tekiniki hamwe nibisabwa
Ikirere
Ubushyuhe mugihe cyubwubatsi no gukiza ni> 10 ℃. Kubaka birabujijwe muminsi yimvura. Ubuso bwumuhanda bugomba gukama nyuma yimvura.
Irinde kubaka mu bihe hamwe n'ubushyuhe ntarengwa buri munsi ya 15 ℃ kugirango ireme ryiza rikomeye.
Ibisabwa mu buryo bw'umwimerere
Imbaraga zubaka zihura nibisabwa, kandi imbaraga zaho ntabwo zidahagije kandi zigomba gushimangirwa.
Ubugari bwa Crack> 5mm birasaba gucika intege, kandi inzerere zidakabije zigomba gucukurwa no gukurura igice gihamye.
Ibipimo ngengabuzima
Imikorere ya Mixture: Ikiziga Cyiza cyambara agaciro ≤500G @G / m2, umucanga wikiziga umucanga ≤450G / m2.
Gutanga umubyimba: Igishushanyo cyagaciro ± 0.5mm, gukosora ibisanzwe gutandukana ≤1.2mm.
Fungura ibijyanye na traffic: ikizamini cyo guhuriza hamwe ≥1.2n · m kugirango hakemure imbaraga zo guhuza.
5. Ikoranabuhanga ryikoranabuhanga
Urusaku ruto
Mugutezimbere amanota no kongeramo ibikoresho bya fibre, urusaku rwo gutwara rushobora kugabanuka na 5-8DB, kandi ibikoreshwa mumihanda yo mumijyi birashobora kunozwa.
Fibre-yashimangiye micro-surfacing
Polyester fibre yongeweho kugirango itezimbere ubushyuhe bwo hejuru no kurwanya, kandi ubuzima bwa serivisi burashobora kongerwa kugeza kumyaka irenga 8.
Ibikoresho byubwubatsi byubwenge
Gutezimbere gahunda yo kugenzura 3D kugirango igere kuri milimetero yo kugenzura no kugabanya imyanda yibikoresho kuri 10% -15%.
Umwanzuro
Umushinga wo kubungabunga micro-surfacing yimihanda minini yabaye ikoranabuhanga ryibanze ryo kwagura ubuzima bwa serivisi no kunoza umutekano wimodoka no kunoza umutekano witwaza hamwe nibiranga "byihuse, neza, ubukungu nubukungu". Mu kugenzura neza uburyo bwibikoresho, ikoranabuhanga ryubwubatsi nubugenzuzi bwiza, inyungu za tekinike zirashobora gukoreshwa byuzuye kugirango utange ibisubizo birambye byo kubungabunga umuhanda.
