I-Micro-surfacing iwubuchwepheshe bokulondoloza obuvimbelayo obusebenzisa ibanga elithile lama-chips amatshe noma isihlabathi, izigcwalisi (usimende, umcako, umlotha wempukane, impushana yamatshe, njll.) kanye ne-polymer-modified emulsified asphalt, izingxube zangaphandle namanzi ngesilinganiso esithile. Hlanganisa ube yingxube egelezayo bese usakaza ngokulinganayo phezu kongqimba lokuvala endaweni yomgwaqo.
Ukuhlaziywa kwesakhiwo somgwaqo kanye nezimbangela zezifo ze-pavement
(1) Ukulawulwa kwekhwalithi yezinto ezingavuthiwe
Ngesikhathi senqubo yokwakha, ukulawulwa kwezinto ezingavuthiwe (i-coarse aggregate diabase, fine aggregate diabase powder, modified emulsified asphalt) kuqala ngezinto zokungena ezihlinzekwe ngumphakeli, ngakho-ke izinto ezinikezwe umphakeli kufanele Kube nombiko wokuhlola osemthethweni. Ngaphezu kwalokho, izinto ezisetshenziswayo zihlolwa ngokuphelele ngokuhambisana namazinga afanele. Phakathi nenqubo yokwakha, izinga lempahla eluhlaza kufanele futhi lihlaziywe. Uma kukhona ukungabaza, ikhwalithi kumele ihlolwe ngokungahleliwe. Ukwengeza, uma kutholakala izinguquko ezintweni ezingavuthiwe, impahla engenisiwe kumele ihlolwe kabusha.
(2) Ukulawulwa kokungaguquguquki kwe-slurry
Ngenqubo yokulinganisa, umklamo wamanzi wengxube ye-slurry unqunywe. Kodwa-ke, ngokusho kwethonya lomswakama esizeni, umswakama we-aggregate, izinga lokushisa lemvelo, umswakama womgwaqo, njll., isayithi ngokuvamile lidinga ukulungisa i-slurry ngokuvumelana nesimo sangempela. Inani lamanzi elisetshenziswe kumxube we-slurry ??lilungiswa kancane ukuze kugcinwe ukuvumelana kwengxube efanele izidingo zokugandaywa.
(3) Ukulawula isikhathi sokususwa kwe-micro-surface demulsification
Ngesikhathi senqubo yokwakhiwa kwe-micro-surfacing yomgwaqo omkhulu, isizathu esibalulekile sezinkinga zekhwalithi ukuthi isikhathi sokukhishwa kwe-demulsification sengxube ye-slurry singaphambi kwesikhathi kakhulu.
Ubukhulu obungalingani, ukuklwebheka, kanye nokuhlukana kwetiyela okubangelwa ukukhishwa kwe-demulsification konke kubangelwa ukukhishwa kwe-amulsification ngaphambi kwesikhathi. Ngokuphathelene nesibopho phakathi kongqimba lokuvala kanye nendawo yomgwaqo, ukukhishwa kwe-mulsification ngaphambi kwesikhathi nakho kuzoba yingozi kakhulu kukho.
Uma kutholakala ukuthi ingxube ikhishwe ngaphambi kwesikhathi, inani elifanele le-retarder kufanele lengezwe ukuze kushintshwe umthamo wesigcwalisi. Futhi uvule iswishi yamanzi angaphambi kokumanzi ukuze ulawule isikhathi sokuphuka.
(4) Ukulawulwa kokuhlukaniswa
Ngesikhathi sokugandaywa kwemigwaqo emikhulu, ukuhlukaniswa kwenzeka ngenxa yezizathu ezinjengogqinsi oluncane lokugandaywa kwezinyawo, ukuhlukaniswa kwengxube ewugqinsi, kanye nokuma komugqa wokumaka (obushelelezi kanye nogqinsi oluthile).
Phakathi nenqubo yokugandaya, kuyadingeka ukulawula ukujiya kokugandaya, ukukala ukujiya kokugandaya ngesikhathi, nokwenza izinguquko ngesikhathi uma kukhona ukusilela okutholakalayo. Uma ukuhlukaniswa kwengxube kumaholoholo kakhulu, ukuhleleka kwengxube ye-slurry kufanele kulungiswe ngaphakathi kwebanga lokudidiyela ukuze kuthuthukiswe isenzakalo sokuhlukaniswa endaweni encane. Ngesikhathi esifanayo, izimpawu zomgwaqo okufanele zigandaywe kufanele zigaywe ngaphambi kokugandaywa.
(5) Ukulawulwa kokuqina kokugandaywa komgwaqo
Enqubweni yokugandaywa kwemigwaqo emikhulu, ukujiya kokugandaya kwengxube ezacile cishe izikhathi ezi-0.95 kuya kwezingu-1.25. Ebangeni lokugreda, ijika kufanele futhi libe seduze nohlangothi olujiyile.
Uma ingxenye yama-aggregates amakhulu ekuhlanganiseni inkulu, kufanele ibekwe ngokushubile, ngaphandle kwalokho ama-aggregate amakhulu awakwazi ukucindezelwa ongqimbeni lokuvala. Ngaphezu kwalokho, kulula futhi ukubangela imihuzuko ku-scraper.
Ngokuphambene nalokho, uma i-aggregate ilungile ngesikhathi senqubo yokulinganisa, khona-ke indawo yomgwaqo egandayiwe kufanele igandaywe ibe mncane ngesikhathi sokugandaywa komgwaqo omkhulu.
Ngesikhathi senqubo yokwakha, ukujiya kokugandaya kumele kulawulwe futhi kuhlolwe ukuze kuqinisekiswe inani lengxube ye-slurry esetshenziswa ekugandayweni komgwaqo omkhulu. Ngaphezu kwalokho, ngesikhathi sokuhlolwa, i-vernier caliper ingasetshenziswa ukukala ngokuqondile uphawu oludakayo endaweni encane yomgwaqo omkhulu osanda kugandaywa. Uma idlula ubukhulu obuthile, ibhokisi lokuphekela kufanele lilungiswe.
(6) Ukulawulwa kokubukeka komgwaqo omkhulu
Ukuze kugandaywe nge-micro-surface emigwaqweni emikhulu, amandla esakhiwo somgwaqo kufanele ahlolwe kusenesikhathi. Uma kuvela ukuxega, amagagasi, ubuthakathaka, imigodi, udaka, nemifantu, lezi zimo zomgwaqo kufanele zilungiswe ngaphambi kokuvala ukwakhiwa.
Phakathi nenqubo yokugandaya, qiniseka ukuthi uyigcina iqondile futhi uqinisekise ukuthi ama-curbs noma izinhlangothi zomgwaqo ziyahambisana. Ukwengeza, lapho kugandaywa, ububanzi bokugandaywa kufanele futhi kuqinisekiswe, futhi amalunga kufanele abekwe ngangokunokwenzeka emgqeni ohlukanisayo ukuze kulawulwe ukuzinza kokuxutshwa futhi kuvimbele izinto ekuhlukaniseni ngaphambi kwesikhathi ebhokisini lokuganda ukuze kuqinisekiswe ukuthi ziyi Inani lamanzi phakathi nenqubo lilinganayo futhi lilinganiselwe.
Ngaphezu kwalokho, zonke izinto kufanele zihlolwe ngesikhathi sokulayisha ukuze kukhishwe izinhlayiya ezinkulu, futhi ukukhubazeka kufanele kulungiswe ngesikhathi ngesikhathi senqubo yokugcwalisa ukuze kugcinwe ukubukeka kwabo bushelelezi futhi kungaguquki.
(7) Ukulawulwa kokuvuleka kwezimoto
Ukuhlola uphawu lwezicathulo kuyindlela yokuhlola evame ukusetshenziswa yekhwalithi yokuvula umgwaqo omkhulu ngesikhathi sokulungiswa komgwaqo onguthelawayeka omncane. Okusho ukuthi, beka isisindo somuntu empandeni noma phansi kwesicathulo bese ume phezu kongqimba lokuvala imizuzwana emibili. Uma i-aggregate ingakhishelwa ngaphandle noma inamathele esicathulweni somuntu lapho ishiya ungqimba oluvaliwe, lungabhekwa njengendawo encane. Ngemva kokuba umsebenzi wokulungisa usuphothuliwe, ungavulelwa ithrafikhi.
