Mu myaka yashize, micro-surfacing yarushijeho gukoreshwa nkigikorwa cyo kubungabunga ibidukikije. Iterambere rya tekinoroji ya micro-surfacing ryanyuze mubyiciro bikurikira kugeza uyu munsi.
Icyiciro cya mbere: gahoro-guturika no gutinda-gushiraho kashe ya kashe. Muri gahunda yimyaka umunani nagatanu, tekinoroji ya asifalt emulifisiyeri yakozwe mugihugu cyanjye ntabwo yari yujuje ubuziranenge, kandi emulisiferi itinda-ishingiye kuri lignine amine yakoreshejwe cyane. Asfalt yakozwe na emulisile yakozwe ni buhoro buhoro kandi buhoro buhoro bwo gushiraho asifalt, bityo bisaba igihe kirekire kugirango ufungure umuhanda nyuma yo gushyirwaho kashe ya kashe, kandi nyuma yubwubatsi ni mbi cyane. Iki cyiciro ni nko kuva 1985 kugeza 1993.
Icyiciro cya kabiri: Hamwe nubushakashatsi bukomeje gukorwa na kaminuza nkuru n’ibigo by’ubushakashatsi mu bya siyansi mu nganda z’imihanda, imikorere ya emulisiferi yarateye imbere, kandi gutinda gutinda no gushiraho byihuse emulifiseri ya asifalt yatangiye kugaragara, cyane cyane anionic sulfonate emulisiferi. Yitwa: gutinda buhoro no gushiraho byihuse kashe. Igihe kiva nko muri 1994 kugeza 1998.

Icyiciro cya gatatu: Nubwo imikorere ya emulisiferi yateye imbere, kashe ya kanyanga ntishobora kubahiriza imiterere itandukanye yumuhanda, kandi hasabwa ibisabwa hejuru kugirango ibipimo ngenderwaho byerekana ibisigazwa bya asfalt, bityo igitekerezo cyo guhindura kashe yahinduwe cyaragaragaye. Styrene-butadiene latex cyangwa chloroprene latex yongewe kuri asfalt ya emulisile. Muri iki gihe, nta bisabwa biri hejuru y'ibikoresho by'amabuye y'agaciro. Iki cyiciro kimara nko mu 1999 kugeza 2003.
Icyiciro cya kane: kugaragara kwa micro-surfacing. Nyuma y’amasosiyete y’amahanga nka AkzoNobel na Medvec yinjiye ku isoko ry’Ubushinwa, ibyo basabwaga ku bikoresho by’amabuye y'agaciro na asifalt ya emulisile yakoreshejwe mu kashe ya slurry yari itandukanye n'ikimenyetso cya kashe. Irashyira kandi ibisabwa hejuru muguhitamo ibikoresho bibisi. Basalt yatoranijwe nkibikoresho byamabuye y'agaciro, umucanga mwinshi uhwanye nibisabwa, wahinduwe na emulisifike asifalt nibindi bintu byitwa micro-surfacing. Igihe ni kuva 2004 kugeza ubu.
Mu myaka yashize, micro-surfacing igabanya urusaku byagaragaye kugirango ikemure ikibazo cyurusaku rwa micro-surfacing, ariko gusaba ntabwo ari byinshi kandi ingaruka ntabwo zishimishije. Kugirango tunonosore indangagaciro ya tensile na shear yuruvange, fibre micro-surfacing yagaragaye; mu rwego rwo gukemura ikibazo cyo kubura amavuta hejuru yumuhanda wambere hamwe no gufatana hagati yuruvange nubuso bwambere bwumuhanda, havutse fibre micro-surfacing yongewemo viscosity.
Kugeza mu mpera za 2020, ibirometero byose by’imihanda ikora mu gihugu hose byageze kuri kilometero 5.1981, muri byo kilometero 161.000 zikaba zarafunguwe ku mihanda minini. Hano haribisubizo bitanu byo gukumira biboneka kubutaka bwa asfalt:
1. Nuburyo bwo gufunga ibicu: igifuniko cyo gufunga igihu, igipande cyumucanga, hamwe numucanga urimo ibicu;
2. Sisitemu yo gufunga amabuye ya kaburimbo: emulisifike ya asfalt ya kashe ya kaburimbo, icyuma gishyushye cya asfalt gishyushye, icyerekezo cya kashe ya asifalt yahinduwe, icyuma gifunga amabuye ya reberi, icyuma gifunga amabuye ya fibre, ubuso bunonosoye;
3. Sisitemu yo gufunga kashe: gufunga ibicuruzwa, guhinduranya kashe;
4. Sisitemu ya Micro-surfacing: micro-surfacing, fibre micro-surfacing, hamwe na viscose fibre micro-surfacing;
5. Sisitemu ishyushye ishyushye: igifuniko cyoroshye, NovaChip ultra-thin yambaye layer.
Muri byo, micro-surfacing ikoreshwa cyane. Ibyiza byayo nuko idafite amafaranga make yo kubungabunga, ariko ikagira nigihe gito cyo kubaka ningaruka nziza zo kuvura. Irashobora kunoza imikorere ya anti-skid yumuhanda, ikarinda amazi yinjira, kunoza isura nuburyo bworoshye bwumuhanda, kandi byongera ubushobozi bwo gutwara imizigo kumuhanda. Ifite ibyiza byinshi byingenzi mukurinda gusaza pavement no kwagura ubuzima bwa serivisi ya pavement. Ubu buryo bwo kubungabunga bukoreshwa cyane mu bihugu byateye imbere nk'Uburayi na Amerika ndetse no mu Bushinwa.
