Nyob rau hauv xyoo tsis ntev los no, micro-surfacing tau dhau los ua ntau dua thiab ntau siv dav siv raws li kev tiv thaiv kev tiv thaiv. Kev txhim kho ntawm micro--surfacing technology tau dhau los ntawm cov theem hauv qab no rau hnub no.
Thawj theem: Qeeb-tawg thiab qeeb-teeb SLURRY Foob. Thaum yim tsib-xyoo phiaj xwm, Exphalt emult kev siv tshuab ua rau hauv kuv lub tebchaws tsis tau nce rau ntawm tus qauv, thiab qeeb tawg emulsifiers raws li Lignin Amine tau siv. Lub emulsified asphalt tsim yog qhov qeeb-tawg thiab qeeb-teeb hom emulsified los qhib, thiab tom qab cov nyhuv yog heev tsis zoo. Qeb no yog kwv yees li ntawm 1985 txog 1993.
Qhov thib ob theem: nrog kev tshawb nrhiav txuas ntxiv ntawm cov tsev kawm qib siab thiab kev tshawb fawb kev tshawb fawb tau pib tshwm sim, feem ntau yog kev ua haujlwm sai sai emulsifiers tau pib tshwm sim, feem ntau yog anionic sulfonate emulsifiers emulsifiers. Nws yog hu ua: Qaum tawg thiab kev teeb tsa ceev slurry foob. Lub sijhawm tshaj tawm hauv xyoo 1994 mus rau 1998.

Qhov thib peb theem: txawm tias kev ua tau zoo ntawm emulsifier tau zoo dua, cov kab npauj npaim tseem tsis tuaj yeem sib ntsib ntawm cov kev ntsuas asphalt, yog li lub tswvyim ntawm kev hloov kho slurry foob tawm. Styrene-Butadiene looj lossis chloroprene latex yog ntxiv rau emulsified asphalt. Nyob rau lub sijhawm no, tsis muaj ib qhov yuav tsum muaj dua rau cov khoom siv ntxhia. Cov theem no kav ntev los ntawm xyoo 1999 txog 2003.
Lub Plaub Theem: Qhov tshwm sim ntawm micro-surfacing. Tom qab cov tuam txhab txawv teb chaws xws li akzonobel thiab medvec tau nkag mus rau hauv cov ntaub ntawv Suav, lawv cov kev xav tau rau cov pob zeb hauv qab thiab emulsified asphalt siv nyob rau hauv cov slurry foob. Nws tseem tso rau cov qib siab dua ntawm kev xaiv ntawm cov ntaub ntawv raw. Basalal yog xaiv raws li cov khoom ntxhia, ntau dua xuab zeb sib npaug, hloov emulsified asphalt thiab lwm yam mob yog hu ua micro-surfacing. Lub sijhawm yog los ntawm 2004 los qhia.
Nyob rau hauv xyoo tsis ntev los no, suab nrov txo micro-surfacing tau tshwm sim los daws cov teeb meem nrov ntawm cov suab paj nruag ntawm micro-surfacing, tab sis daim ntawv thov tsis yog ntau thiab cov nyhuv tsis txaus ntseeg. Txhawm rau txhim kho lub tensile thiab shear index ntawm cov sib tov, fiber ntau micro-surfacing tau tshwm sim; Txhawm rau daws qhov teeb meem ntawm cov roj depletion ntawm txoj kev qub ntawm txoj kev qub thiab cov nplaum ntawm kev sib xyaw thiab cov viscosity-sprancosing-surfacing tau yug los.
Raws li qhov kawg ntawm 2020, tag nrho cov mais kev ntawm kev loj hauv kev ua haujlwm thoob plaws 5.1981 lab km thiab 161,000 mais tau qhib rau cov tsheb ntawm kev nthuav dav. Muaj kwv yees tsib leeg tiv thaiv kev tswj cov kev daws teeb meem muaj rau asphalt pavement:
1. Lawv tau posting txheej txheej: huab txaws txheej, xuab zeb sealing txheej, thiab cov xuab zeb uas muaj huab sib khi txheej;
2. Gravel sealing System: Emulsified Asphalt Gravting Txheej, Recent As Asceler Graving Txheej, Fiber ntau Gravel Foob, kho kom zoo;
3. Slurry sealing System: Slurry sealing, hloov kho slurry sealing;
4. Micro-Surfacing System: Micro-surfacing, fiber ntau micro-surfacing, thiab viscose fiber ntau micro-surfacing;
5. Kub nteg system: nyias txheej txheej npog, Novachip ultra-nyias hnav txheej.
Ntawm lawv, micro-surfacing yog dav siv. Nws cov txiaj ntsig yog tias nws tsis tsuas yog muaj cov nqi kho mob tsawg, tab sis kuj muaj lub sijhawm tsim kho luv luv thiab kev kho mob kom zoo. Nws tuaj yeem txhim kho kev ua yeeb yam los ntawm txoj kev, tiv thaiv cov dej saib dej, txhim kho kev ua kom zoo thiab ua kom muaj peev xwm ua kom muaj peev xwm ntawm txoj kev. Nws muaj ntau yam zoo heev nyob rau hauv kev tiv thaiv kev tiv thaiv kev pua chaw thiab nthuav tawm kev pabcuam lub neej ntawm kev pavement. Txoj kev txij nkawm no tau siv dav hauv cov teb chaws tsim tau xws li Tebchaws Europe thiab Asmeskas nrog rau Suav.
