Maka microsurfacing, ngwakọta ngwakọta ọ bụla mepụtara bụ nnwale ndakọrịta, nke ọtụtụ mgbanwe dị ka emulsified asphalt na aggregate ụdị, mkpokọta gradation, mmiri na emulsified asphalt ego, na ụdị nke ịnweta fillers na mgbakwunye. . Ya mere, nyocha nnwale ịme anwansị na saịtị nke nlele ụlọ nyocha n'okpuru ọnọdụ injinịa akọwapụtara abụrụla isi ihe na-enyocha arụmọrụ nke ngwakọta micro-surface. A na-ewebata ọtụtụ ule a na-ejikarị dị ka ndị a:
1. Ngwakọta ule
Ebumnuche bụ isi nke ule agwakọta bụ iji mee ka ebe a na-ewu ihe mgbochi. Nkwekọrịta nke emulsified asphalt na aggregates bụ nkwenye site na ọnọdụ ịkpụzi nke micro-surface, na oge ngwakọta kpọmkwem na nke ziri ezi na-enweta. Ọ bụrụ na oge ngwakọta ahụ dị ogologo, elu okporo ụzọ agaghị eru ike mmalite ma ọ gaghị emeghe okporo ụzọ; ọ bụrụ na oge agwakọta dị mkpụmkpụ, ihe owuwu ụzọ mbata ahụ agaghị adị mma. Mmetụta ihe owuwu nke micro-surfacing na-emetụta ngwa ngwa site na gburugburu ebe obibi. Ya mere, mgbe ị na-emepụta ngwakọta ahụ, a ghaghị ịnwale oge ngwakọta n'okpuru ọnọdụ ọjọọ nke nwere ike ime n'oge a na-ewu ụlọ. Site na usoro nyocha nke arụmọrụ, a na-enyocha ihe ndị na-emetụta arụmọrụ nke ngwakọta micro-surface n'ozuzu ya. Nkwubi okwu ndị a bụ ndị a: 1. Okpomọkụ, ọnọdụ okpomọkụ dị elu nwere ike ibelata oge ngwakọta; 2. Emulsifier, nke ukwuu na dose nke emulsifier, ogologo oge ịgwakọta; 3. Simenti, ịgbakwunye ciment nwere ike ịgbatị ma ọ bụ belata ngwakọta. A na-ekpebi oge ngwakọta site na njirimara nke emulsifier. N'ozuzu, ka ọnụ ọgụgụ ahụ dị ukwuu, oge ngwakọta ahụ dị mkpụmkpụ. 4. Ọnụ ọgụgụ nke mmiri na-agwakọta mmiri, ka mmiri na-eme ka mmiri dị ukwuu, na-agbatịkwu oge ịgwakọta. 5. Uru pH nke ngwọta ncha na-abụkarị 4-5 na oge ngwakọta dị ogologo. 6. Ka ikike zeta dị ukwuu nke emulsified asphalt na usoro oyi akwa eletrik okpukpu abụọ nke emulsifier, ogologo oge ngwakọta ahụ.

2. Nnwale adhesion
Na-anwale ike mmalite nke micro elu, nke nwere ike tụọ oge ntọala mbụ nke ọma. Ike mmalite zuru oke bụ ihe dị mkpa iji hụ na oge mmeghe maka okporo ụzọ. Ọ dị mkpa ka a nyochaa ntinye nke adhesion n'ụzọ zuru ezu, na ọnụ ahịa adhesion a tụrụ atụ kwesịrị ijikọta ya na ọnọdụ mmebi nke ihe nlele ahụ iji chọpụta oge ntọala mbụ na imeghe oge okporo ụzọ nke ngwakọta.
3. Wet wheel yi ule
Nnwale abrasion wheel mmiri na-eme ka okporo ụzọ nwee ike iguzogide eyi taya mgbe mmiri dị.
Nnwale abrasion wheel mmiri nke otu awa nwere ike ikpebi nguzogide abrasion nke oyi akwa arụ ọrụ microsurface na ihe mkpuchi nke asphalt na mkpokọta. Mgbochi mmebi mmiri nke ngwakọta asphalt emulsified nke micro-surface gbanwetụrụ bụ nke uru uwe ụbọchị 6 na-anọchi anya ya, a na-enyocha mmebi mmiri nke ngwakọta ahụ site na ogologo usoro ntinye ogologo. Otú ọ dị, mmebi nke mmiri na-egosi na ọ bụghị nanị na ngbanwe nke akpụkpọ anụ asphalt, kamakwa mgbanwe nke ọnọdụ oge nke mmiri nwere ike imebi ngwakọta. Nnwale abrasion nke imikpu ụbọchị isii ahụ eburughị n'uche mmetụta nke ntugharị mmiri na-agbaze na ọla na mpaghara oyi nke oge. Na ntu oyi ebili na peeling mmetụta mere site asphalt film n'elu ihe. Ya mere, dabere na ụbọchị 6 mmiri imikpu mmiri wiwi abrasion ule, a na-eme atụmatụ ịnakwere ule abrasion wet wheel nke friza iji gosipụta nke ọma mmetụta ọjọọ nke mmiri na ngwakọta micro-surface.
4. Rutting deformation ule
Site na ule nrụrụ rutting, enwere ike nweta ọnụọgụ nrụrụ obosara nke wheel track, enwere ike nyochaa ikike mgbochi nke ngwakọta micro-surface. Obere nrụrụ obosara nke obosara, otú ahụ ka ike na-esiwanye ike iguzogide nrụrụ rutting na mma nkwụsi ike okpomọkụ dị elu; N'aka nke ọzọ, nke ka njọ ike iguzogide nrụrụ rutting. Ọmụmụ ihe ahụ chọpụtara na ọnụọgụ nrụrụ obosara nke ụkwụ ụkwụ nwere njikọ doro anya na ọdịnaya asphalt emulsified. Ka ọdịnaya asphalt nke emulsified na-abawanye, na-akawanye njọ nguzogide nbibi nke ngwakọta micro-elu. O mere ka ọ pụta ìhè na nke a bụ n'ihi na mgbe a na-etinye polymer emulsified asphalt n'ime ihe nkedo inorganic nke dabeere na ciment, modul na-agbanwe nke polymer dị nnọọ ala karịa nke simenti. Mgbe mmeghachi omume ngwakọta ahụ gasịrị, ihe ndị dị na cimenti na-agbanwe, na-eme ka mbelata n'ozuzu siri ike. N'ihi ya, nrụrụ track wheel na-abawanye. Na mgbakwunye na ule ndị a dị n'elu, a ga-edozi ọnọdụ ule dị iche iche dị ka ọnọdụ dị iche iche si dị, a ga-eji ule ngwakọta dị iche iche mee ihe. N'ime ihe owuwu n'ezie, ngwakọta ngwakọta, karịsịa oriri mmiri nke ngwakọta na oriri ciment, nwere ike gbanwee nke ọma dịka ihu igwe dị iche iche na okpomọkụ.
Mkpebi: Dị ka teknụzụ na-egbochi mgbochi, micro-surfacing nwere ike imeziwanye arụmọrụ zuru oke nke pavement ma kpochapụ mmetụta nke ọrịa dị iche iche na pavement nke ọma. N'otu oge ahụ, ọ nwere ọnụ ala dị ala, obere oge ihe owuwu na mmetụta nlekọta dị mma. Edemede a na-enyocha nhazi nke ngwakọta micro-surfacing, na-enyocha mmetụta ha n'ozuzu ya, na-ewebata ma na-achikota nkenke ule arụmọrụ nke ngwakọta micro-surfacing na nkọwa ndị dị ugbu a, nke nwere nkọwa dị mma maka nyocha miri emi n'ọdịnihu.
Ọ bụ ezie na nkà na ụzụ micro-surfacing aghọwo ihe na-eto eto, ọ ka kwesịrị ka a na-enyocha ya ma mepụta ya iji melite ọkwa nkà na ụzụ iji meziwanye ma kwalite arụmọrụ zuru oke nke okporo ụzọ okporo ụzọ na izute mkpa nke ọrụ okporo ụzọ. Tụkwasị na nke ahụ, n'oge usoro ihe owuwu nke micro-surfacing, ọtụtụ ọnọdụ dị n'èzí na-enwe mmetụta dịtụ kpọmkwem n'ịdị mma nke ọrụ ahụ. Ya mere, a ghaghị ịtụle ọnọdụ ihe owuwu ahụ n'ezie na a ga-ahọrọ usoro nlekọta sayensị ndị ọzọ iji hụ na e nwere ike imejuputa ihe owuwu micro-surfacing nke ọma ma nweta Iji meziwanye mmetụta mmezi ahụ.
