N'afọ ndị na-adịbeghị anya, micro-surfacing aghọwo ihe a na-ejikarị eme ihe dị ka usoro nlekọta mgbochi. Mmepe nke teknụzụ micro-surfacing agafeela usoro ndị a ruo taa.
Usoro nke mbụ: akara slurry na-eji nwayọ na-eji nwayọ. N'ime atụmatụ afọ ise nke asatọ, teknụzụ asphalt emulsifier emepụtara na mba m erughị oke, na emulsifiers na-eji nwayọ nwayọ dabere na lignin amine na-ejikarị eme ihe. Asphalt emulsified emepụtara bụ ụdị asphalt nke emulsified nke na-agbawa ngwa ngwa na nke na-adịghị ngwa ngwa, ya mere ọ na-ewe ogologo oge iji mepee okporo ụzọ ahụ mgbe etinyere akara slurry, na mmetụta nrụpụta mgbe arụchara adịghị mma. Oge a dị ihe dịka 1985 ruo 1993.
Nkeji nke abụọ: Site na nyocha na-aga n'ihu nke mahadum ndị isi na ụlọ ọrụ nyocha sayensị na ụlọ ọrụ awara awara, arụmọrụ nke emulsifiers abawanyela, na ngwa ngwa mgbawa na ntọala asphalt emulsifiers amalitela ịpụta, ọkachasị anionic sulfonate emulsifiers. A na-akpọ ya: ngwa ngwa cracking na ngwa ngwa ịtọ akara slurry. Oge ahụ sitere na 1994 ruo 1998.

Nkeji nke atọ: Ọ bụ ezie na arụmọrụ nke emulsifier ka dị mma, akara slurry enweghị ike izute ọnọdụ ụzọ dị iche iche, a na-etinyekwa ihe ndị dị elu maka ihe ngosi arụmọrụ nke ihe fọdụrụ nke asphalt, ya mere echiche nke slurry akara gbanwere. Styrene-butadiene latex ma ọ bụ chloroprene latex na-agbakwunyere na emulsified asphalt. N'oge a, ọ dịghị ihe dị elu chọrọ maka ihe ịnweta mineral. Oge a dịruru ihe dịka 1999 ruo 2003.
Nkeji nke anọ: mpụta nke micro-surfacing. Mgbe ụlọ ọrụ si mba ọzọ dị ka AkzoNobel na Medvec banyere n'ahịa ndị China, ihe ha chọrọ maka ihe ndị dị na ịnweta na emulsified asphalt eji na slurry seal dị iche na nke slurry seal. Ọ na-etinyekwa ihe ndị dị elu chọrọ na nhọrọ nke akụrụngwa. A na-ahọrọ Basalt dị ka ihe ịnweta ịnweta, ájá dị elu nke chọrọ, gbanwetụrụ emulsified asphalt na ọnọdụ ndị ọzọ na-akpọ micro-surfacing. Oge a sitere na 2004 ruo ugbu a.
N'ime afọ ndị na-adịbeghị anya, micro-surfacing na-ebelata mkpọtụ apụtawo iji dozie nsogbu mkpọtụ nke micro-surfacing, ma ngwa ahụ adịghị ọtụtụ na mmetụta adịghị mma. Iji meziwanye nkwụsịtụ na nkwụsị nke ngwakọta, eriri micro-surfacing apụtawo; iji dozie nsogbu nke mmanu mmanu nke uzo uzo mbu na nchikota n'etiti ngwakọta na uzo uzo mbu, a mụrụ viscosity-agbakwunyere fiber micro-surfacing.
Ka ọ na-erule njedebe nke 2020, ngụkọta nke okporo ụzọ awara awara na-arụ ọrụ na mba ahụ ruru nde kilomita 5.1981, nke 161,000 kilomita mepere maka okporo ụzọ n'okporo ụzọ awara awara. Enwere ihe ngwọta mgbochi mgbochi ise dị maka pavement asphalt:
1. Ha bụ foogu sealing oyi akwa usoro: foogu sealing oyi akwa, ájá akara oyi akwa, na ájá nwere foogu sealing oyi akwa;
2. Gravel akara usoro: emulsified asphalt gravel sealing oyi akwa, na-ekpo ọkụ asphalt gravel sealing oyi akwa, gbanwetụrụ asphalt gravel sealing oyi akwa, roba asphalt gravel sealing oyi akwa, eriri gravel sealing oyi akwa, nụchara anụcha elu;
3. Slurry sealing system: slurry sealing, modified slurry sealing;

5. Hot Ịtọgbọ usoro: mkpa oyi akwa mkpuchi, NovaChip ultra-mkpa yi oyi akwa.
N'ime ha, a na-ejikarị micro-surfacing eme ihe. Uru ya bụ na ọ bụghị naanị na ọ nwere ụgwọ ọrụ dị ala, kamakwa ọ nwere obere oge ihe owuwu na mmetụta ọgwụgwọ dị mma.
