Mumakore achangopfuura, micro-surfacing yakawedzera kushandiswa zvakanyanya senzira yekudzivirira yekuchengetedza. Iko kuvandudzwa kweiyo micro-surfacing tekinoroji yakapfuura nematanho anotevera kusvika nhasi.
Nhanho yekutanga: kunonoka-kutsemuka uye kunonoka-kuseta slurry chisimbiso. Munguva yeEighth-Fire Plan Plan, tekinoroji yeasphalt emulsifier yakagadzirwa munyika yangu yakanga isiri kusvika pachiyero, uye inononoka-crack emulsifiers yakavakirwa pa lignin amine yainyanya kushandiswa. Iyo emulsified asphalt inogadzirwa inononoka-inotsemuka uye inononoka-inogadzika mhando ye emulsified asphalt, saka zvinotora nguva yakareba kuti uvhure traffic mushure mekunge slurry chisimbiso chaiswa, uye mushure mekuvaka mhedzisiro yakaipa kwazvo. Danho iri rinenge kubva 1985 kusvika 1993.
Danho rechipiri: Nekuenderera mberi nekutsvagisa kwemayunivhesiti makuru uye masangano ekutsvagisa esainzi muindasitiri yemigwagwa mikuru, kuita kwe emulsifiers kwave nani, uye kunonoka kutsemuka uye nekukurumidza kuseta asphalt emulsifiers kwave kutanga kuoneka, kunyanya anionic sulfonate emulsifiers. Inonzi: kunonoka kutsemuka uye nekukurumidza kuseta slurry chisimbiso. Nguva yacho inotangira munenge muna 1994 kusvika muna 1998.

Danho rechitatu: Kunyangwe kuita kwe emulsifier kwave nani, chisimbiso chinotsvedza hachisati chakwanisa kusangana nemamiriro akasiyana emigwagwa, uye zvinodiwa zvepamusoro zvinoiswa pamberi pezviratidzo zvekushanda kwemasara easphalt, saka pfungwa yekugadziriswa slurry chisimbiso chakabuda. Styrene-butadiene latex kana chloroprene latex inowedzerwa kune emulsified asphalt. Panguva ino, hapana chepamusoro zvinodiwa zvemamineral zvinhu. Iyi nhanho inotangira kubva munenge muna 1999 kusvika muna 2003.
Nhanho yechina: kubuda kwe micro-surfacing. Mushure mekunge makambani ekunze akadai seAkzoNobel neMedvec apinda mumusika weChinese, zvavanoda zvemamineral materials uye emulsified asphalt inoshandiswa muslurry chisimbiso zvaive zvakasiyana neaya echisimbiso che slurry. Inoisawo zvinodiwa zvepamusoro pakusarudzwa kwezvinhu zvakasvibiswa. Basalt inosarudzwa semamineral material, yakakwira jecha yakaenzana zvinodiwa, yakagadziridzwa emulsified asphalt uye mamwe mamiriro anonzi micro-surfacing. Nguva yacho kubva 2004 kusvika ikozvino.
Mumakore achangopfuura, ruzha-inoderedza micro-surfacing yakaonekwa kugadzirisa dambudziko reruzha rwe micro-surfacing, asi application haina kuwanda uye mhedzisiro yacho haina kugutsa. Kuti uvandudze tensile uye shear index yemusanganiswa, fiber micro-surfacing yakaonekwa; kuitira kugadzirisa dambudziko rekuderera kwemafuta emugwagwa wepakutanga uye kunamatira pakati pemusanganiswa nemugwagwa wepakutanga, iyo viscosity-yakawedzerwa fiber micro-surfacing yakazvarwa.
Kubva pakupera kwa2020, mileage yese yemigwagwa mikuru iri kushanda munyika yose yakasvika 5.1981 miriyoni makiromita, ayo 161,000 makiromita akavhurika kune traffic mumigwagwa. Kune angangoita mashanu ekudzivirira ekugadzirisa mhinduro anowanikwa kune asphalt pavement:
1. Idzi ifog sealing layer system: fog sealing layer, jecha sealing layer, uye jecha-ine mhute sealing layer;
2. Gravel sealing system: emulsified asphalt gravel sealing layer, inopisa asphalt gravel sealing layer, modified asphalt gravel sealing layer, rubber asphalt gravel sealing layer, fiber gravel sealing layer, yakanatswa;
3. Slurry sealing system: slurry sealing, yakagadziriswa slurry sealing;
4. Micro-surfacing system: micro-surfacing, fiber micro-surfacing, uye viscose fiber micro-surfacing;
5. Hot laying system: yakaonda layer cover, NovaChip Ultra-yakaonda kupfeka layer.
Pakati pavo, micro-surfacing inoshandiswa zvakanyanya. Zvakanakira zvayo ndezvokuti haisi kungoita mari shoma yekuchengetedza, asiwo ine nguva pfupi yekuvaka uye maitiro akanaka ekurapa. Inogona kuvandudza maitiro e-anti-skid emugwagwa, kudzivirira kubuda kwemvura, kugadzirisa kutaridzika uye kutsetseka kwemugwagwa, uye kuwedzera kutakura mutoro wemugwagwa. Iyo ine zvakawanda zvakatanhamara zvakanakira kudzivirira kuchembera kwepavement uye kuwedzera hupenyu hwesevhisi yemugwagwa. Iyi nzira yekuchengetedza inoshandiswa zvakanyanya munyika dzakabudirira dzakadai seEurope neUnited States pamwe chete neChina.
