Micro-surfacing bụ a mgbochi mmezi technology na-eji a ụfọdụ ọkwa nke nkume ibe ma ọ bụ ájá, fillers (ciment, wayo, ofufe ash, nkume ntụ ntụ, wdg) na polymer-gbanwetụrụ emulsified asphalt, mpụga admixtures na mmiri n'otu akụkụ. Gwakọta ya n'ime ngwakọta nke nwere ike ịgbasa wee gbasaa ya n'elu akwa mkpuchi n'elu okporo ụzọ.

Nyocha nke usoro pavement na ihe kpatara ọrịa pavement
(1) Njikwa ogo akụrụngwa
N'oge usoro ihe owuwu ahụ, njikwa nke akụrụngwa (nchịkọta mkpokọta diabase, ezigbo nchịkọta diabase ntụ ntụ, gbanwetụrụ emulsified asphalt) na-amalite site na ntinye ntinye nke onye na-ebubata ya na-enye, ya mere ihe ndị na-ebubata ya ga-enwerịrị akwụkwọ akụkọ nyocha. Ọzọkwa, a na-enyocha ihe ndị ahụ n'ụzọ zuru ezu dịka ụkpụrụ dị mkpa si dị. N'oge usoro ihe owuwu, a ga-enyochakwa ịdị mma nke akụrụngwa. Ọ bụrụ na enwere obi abụọ ọ bụla, a ga-enyocharịrị ogo ya na enweghị usoro. Na mgbakwunye, ọ bụrụ na achọpụtara mgbanwe na akụrụngwa, a ga-enyochagharị ihe ndị ebubata.
(2) Njikwa nke slurry agbanwe agbanwe
N'ime usoro nhazi, a na-ekpebi nhazi mmiri nke ngwakọta slurry. Otú ọ dị, dị ka mmetụta nke iru mmiri dị na saịtị ahụ, ọdịnaya mmiri nke nchịkọta, okpomọkụ nke gburugburu ebe obibi, mmiri mmiri nke okporo ụzọ, wdg, saịtị ahụ na-achọkarị imezi slurry dịka ọnọdụ dị adị. Ọnụ ego nke mmiri na-eji na slurry mix bụ 'gbanwee ntakịrị iji nọgide na-agbanwe agbanwe nke ngwakọta kwesịrị ekwesị maka mkpa paving.
(3) Micro-surface demulsification njikwa oge
N'oge usoro ihe owuwu nke micro-surfacing okporo ụzọ, otu ihe dị mkpa kpatara nsogbu dị mma bụ na oge nkwụsị nke ngwakọta slurry dị n'oge.
Ọkpụrụkpụ na-ekwekọghị ekwekọ, ncha, na adịghị n'otu nke asphalt kpatara site na demulsification bụ ihe na-akpata mbibi akabeghị aka. N'ihe gbasara njikọ dị n'etiti mkpuchi mkpuchi na elu okporo ụzọ, demulsification nke akabeghị aka ga-emerụkwa ya ahụ nke ukwuu.
Ọ bụrụ na achọpụtara na ngwakọta ahụ na-agbaze n'oge akaghi aka, a ga-agbakwunye ego retarder kwesịrị ekwesị iji gbanwee usoro nke ndochi. Ma gbanye mgba ọkụ tupu mmiri mmiri iji chịkwaa oge nkwụsịtụ.
(4) Njikwa nkewa
N'oge a na-emepe ụzọ okporo ụzọ awara awara, nkewa na-eme n'ihi ihe ndị dị ka ọkpụrụkpụ paving dị warara, gradation ngwakọta siri ike, na ọnọdụ akara akara (dị nro na nke nwere ụfọdụ ọkpụrụkpụ).
N'oge a na-eme ihe mgbochi, ọ dị mkpa ijikwa ihe nkedo ahụ, tụọ ihe mgbochi n'oge, ma mee mgbanwe n'oge ma ọ bụrụ na achọtaghị ihe ọ bụla. Ọ bụrụ na gradation nke ngwakọta dị oke oke, a ga-edozi gradation nke ngwakọta slurry n'ime oke gradation iji meziwanye ihe nkewa nkewa na micro elu. N'otu oge ahụ, a ga-egweri akara okporo ụzọ a ga-eji mee ihe tupu ịkwa akwa.
(5) Nchikota nke ịhịa aka n'okporo ụzọ
N'ime usoro imeghe nke okporo ụzọ awara awara, ihe mgbochi nke ngwakọta nke thinner bụ ihe dịka 0.95 ruo 1.25 ugboro. N'ọkwa ọkwa ọkwa, ọkpụkpụ ahụ kwesịkwara ịdị nso n'akụkụ nke buru ibu.
Mgbe oke nke nnukwu nchịkọta dị na nchịkọta dị ukwuu, a ghaghị ịtọpụ ya ka ọ dị elu, ma ọ bụghị ya, a pụghị ịpịnye nnukwu ihe nchịkọta n'ime mkpuchi mkpuchi. Ọzọkwa, ọ dịkwa mfe ime ka scratches na scraper.
N'ụzọ megidere nke ahụ, ọ bụrụ na nchịkọta ahụ dị mma n'oge usoro nhazi nke nha, mgbe ahụ, a ga-emepe ụzọ awara awara awara awara n'oge a na-emepe emepe okporo ụzọ.
N'oge usoro ihe owuwu ahụ, a ga-ejikwa ma nwalee ọkpụrụkpụ nke paving ahụ iji hụ na ọnụọgụ slurry nke a na-eji eme ihe n'okporo ụzọ awara awara. Na mgbakwunye, mgbe a na-enyocha ya, enwere ike iji vernier caliper tụọ akara slurry ozugbo n'elu obere elu nke okporo ụzọ awara awara ọhụrụ. Ọ bụrụ na ọ gafere ụfọdụ ọkpụrụkpụ, a ga-edozirịrị igbe paver ahụ.
(6) Njikwa ọdịdị okporo ụzọ
Maka mkpirisi obere ihe n'okporo ụzọ awara awara, a ga-anwale ike nhazi nke elu ụzọ ahụ n'ọdịnihu. Ọ bụrụ ntọhapụ, ebili mmiri, adịghị ike, olulu mmiri, slurry, na mgbawa pụtara, a ga-edozirịrị ọnọdụ okporo ụzọ ndị a tupu ị mechie owuwu.
N'oge a na-eme ihe mgbochi, jide n'aka na ị ga-eme ka ọ kwụ ọtọ ma hụ na ọgịga ma ọ bụ n'akụkụ okporo ụzọ bụ otu. Tụkwasị na nke ahụ, mgbe ị na-emepe emepe, a ghaghị ijide n'aka na obosara ihe nkedo ahụ kwesịrị ijide n'aka, a ga-etinyekwa nkwonkwo dị ka o kwere mee n'ahịrị nkewa nkewa iji chịkwaa nkwụsi ike nke ngwakọta ahụ ma gbochie ihe ndị ahụ site n'ikewapụ n'oge na-adịghị anya n'ime igbe mpempe akwụkwọ iji hụ na. ha bụ Ọnụ mmiri n'oge usoro ahụ bụ ọbụna na agafeghị oke.
Tụkwasị na nke ahụ, a ga-enyocha ihe niile n'oge a na-ebunye ihe iji wepụ ihe ndị buru ibu, na ntụpọ ga-adị mma n'oge n'oge usoro njuputa iji mee ka ọdịdị ha dị mma ma na-agbanwe agbanwe.
(7) Njikwa oghere okporo ụzọ
Nnwale akara akpụkpọ ụkwụ bụ usoro nyocha nke a na-ejikarị maka mmeghe okporo ụzọ n'oge mmezi okporo ụzọ micro-surface. Ya bụ, tinye ibu onye ahụ na mgbọrọgwụ ma ọ bụ ala akpụkpọ ụkwụ ma guzoro n'elu mkpuchi mkpuchi maka sekọnd abụọ. Ọ bụrụ na ewepụtaghị mkpokọta ahụ ma ọ bụ rapara na akpụkpọ ụkwụ onye ahụ mgbe ọ na-ahapụ elu akwa mkpuchi ahụ, enwere ike iwere ya dị ka micro elu. Mgbe arụchara ọrụ mmezi ahụ, enwere ike imeghe ya na okporo ụzọ.
