Micro-surfacing nubuhanga bwo gukumira bukoresha urwego runaka rwibibuye cyangwa umucanga, byuzuza (sima, lime, ivu ryisazi, ifu yamabuye, nibindi) hamwe na polymer-yahinduwe na emulisifike asifalt, ibivanze hanze namazi muburyo runaka. Kuvangavanga uruvange rutemba hanyuma urukwirakwize hejuru yikimenyetso hejuru yumuhanda.
Isesengura ryimiterere ya pavement nimpamvu zindwara za pavement
(1) Kugenzura ubuziranenge bwibikoresho fatizo
Mugihe cyubwubatsi, kugenzura ibikoresho bibisi (coarse agregate diabase, ifu nziza ya diabase ifu, ifu ya emulisifike yahinduwe) itangirana nibikoresho byinjira byatanzwe nuwabitanze, bityo ibikoresho byatanzwe nuwabitanze bigomba kuba hari raporo yikizamini cyemewe. Byongeye kandi, ibikoresho bigenzurwa byimazeyo hakurikijwe ibipimo bifatika. Mugihe cyubwubatsi, ubwiza bwibikoresho fatizo nabwo bugomba gusesengurwa. Niba hari ugushidikanya, ubuziranenge bugomba kugenzurwa ku bushake. Byongeye kandi, niba habonetse impinduka mubikoresho bibisi, ibikoresho byatumijwe hanze bigomba kongera kugeragezwa.
(2) Kugenzura guhuzagurika
Muburyo bwo kugereranya, igishushanyo mbonera cyamazi yimvange ya slurry cyagenwe. Nyamara, ukurikije ingaruka zubushuhe kurubuga, ibirimo ubuhehere bwa agregate, ubushyuhe bwibidukikije, ubuhehere bwumuhanda, nibindi, ikibanza gikenera guhindura ibishishwa ukurikije uko ibintu bimeze. Umubare wamazi akoreshwa muruvange rwa slurry arahinduka ?? yahinduwe gato kugirango akomeze guhuza imvange ikwiranye no gukenera pave.
(3) Kugenzura igihe-Micro-surface demulation
Mugihe cyo kubaka micro-surfacing inzira yo kubaka, impamvu yingenzi yibibazo byubuziranenge nuko igihe cyo gusenya imvange ya slurry ari kare cyane.
Ubunini butaringaniye, gushushanya, no kutavuga rumwe kwa asfalt biterwa no gusezererwa byose biterwa no gusezererwa imburagihe. Kubireba isano iri hagati yikimenyetso hamwe nubuso bwumuhanda, gusenya imburagihe nabyo bizabangamira cyane.
Niba bigaragaye ko imvange yavanyweho imburagihe, umubare ukwiye wa retarder ugomba kongerwaho kugirango uhindure dosiye yuzuza. Kandi fungura amazi yabanjirije amazi kugirango ugenzure igihe cyo kumena.
(4) Kugenzura amacakubiri
Mugihe cyo gutunganya inzira nyabagendwa, gutandukanya bibaho bitewe nimpamvu nkubunini bwa pave yoroheje, kuvanga umubyimba mwinshi, hamwe no kwerekana umurongo (byoroshye kandi bifite umubyimba runaka).
Mugihe cya pave, birakenewe kugenzura uburebure bwa pave, gupima uburebure bwa pave mugihe, no guhindura mugihe mugihe hari ibitagenda neza. Niba itondekanya ryuruvange ari rito cyane, itondekanya ryuruvange rwa slurry rugomba guhindurwa murwego rwo gutondekanya kugirango tunonosore ibintu byo gutandukanya hejuru ya micro. Muri icyo gihe, ibimenyetso byumuhanda ugomba gushyirwaho bigomba gusya mbere yo kubitaka.
(5) Kugenzura ubugari bwa kaburimbo
Muburyo bwo gutunganya umuhanda munini, uburebure bwa pave bwuruvange rworoshye ni inshuro 0,95 kugeza 1.25. Mu ntera yo gutondekanya, umurongo ugomba no kuba hafi kuruhande rwijimye.
Iyo igipimo cyibintu byinshi byegeranijwe ari binini, bigomba gushyirwaho umubyimba, bitabaye ibyo igiteranyo kinini ntigishobora gukandamizwa murwego rwo gufunga. Byongeye kandi, biroroshye kandi gutera ibishushanyo kuri scraper.
Ibinyuranye na byo, niba igiteranyo ari cyiza mugihe cyo kugereranya, noneho umuhanda wa kaburimbo ugomba kuba wubatswe neza mugihe cyo gutunganya umuhanda.
Mugihe cyubwubatsi, ubunini bwa kaburimbo nabwo bugomba kugenzurwa no kugeragezwa kugirango harebwe ingano yimvange ivanze ikoreshwa mumihanda minini. Byongeye kandi, mugihe cyo kugenzura, Caliper ya vernier irashobora gukoreshwa mugupima kashe ya kashe kuri micro-hejuru yumuhanda mushya wa kaburimbo. Niba irenze umubyimba runaka, agasanduku ka paver kagomba guhinduka.
(6) Kugenzura isura yumuhanda
Kubutaka bwa micro-busa kumihanda, imbaraga zububiko bwumuhanda zigomba kugeragezwa hakiri kare. Niba hagaragaye ubunebwe, imivumba, intege nke, ibinogo, ibishishwa, hamwe n’imvune, iyi mihanda igomba gusanwa mbere yo gushyirwaho kashe.
Mugihe cyo gutunganya kaburimbo, menya neza ko ugumya kugororoka kandi urebe ko umuhanda cyangwa umuhanda uhwanye. Byongeye kandi, mugihe cya pave, ubugari bwa pave nabwo bugomba gukemurwa, kandi ingingo zigomba gushyirwa kure hashoboka kumurongo ugabanya umurongo kugirango ugenzure ituze ryivanga kandi wirinde ko ibikoresho bitandukana hakiri kare mumasanduku ya kaburimbo kugirango barebe ko ni Ingano y'amazi mugihe cyibikorwa niyo iringaniye.
Byongeye kandi, ibikoresho byose bigomba kugenzurwa mugihe cyo gupakira kugirango bikureho ibice binini, kandi inenge zigomba koroshya mugihe mugihe cyo kuzuza kugirango isura yabo igende neza kandi ihamye.
(7) Kugenzura gufungura umuhanda
Ikizamini cyikimenyetso cyinkweto nuburyo bukunze kugenzurwa kugirango hafungurwe umuhanda mugihe cyo gufata neza umuhanda muto. Nukuvuga, shyira uburemere bwumuntu kumuzi cyangwa munsi yinkweto hanyuma uhagarare kumurongo wa kashe kumasegonda abiri. Niba igiteranyo kidasohotse cyangwa ngo gifatwe ku nkweto z'umuntu mugihe cyo kuva hejuru yikimenyetso, birashobora gufatwa nkubuso bwa micro. Ibikorwa byo kubungabunga birangiye, birashobora gukingurwa mumodoka.
