I. Kev txhais thiab cov ntsiab lus zoo
Txoj haujlwm tswj hwm micro chaw yog ib txoj kev tiv thaiv kev txij nkawm raws li kev txhim kho ntawm slurry foob thev naus laus zis. Nws cov tub ntxhais nyob hauv kev siv polymer-hloov emulsified asphalt, uas yog cov kua txiv ntoo uas sib xyaw ua ke los ntawm cov khoom siv tshwj xeeb los ua ib qho txheej txheem tshwj xeeb. Cov thev naus laus zis no muaj qhov tseem ceeb hauv qab no:

Kev tsim kho ceev thiab qhib kev tsheb
Kev tsim kho hauv chav tsev kub, tsis tas yuav tsum muaj cov khoom cua sov, tsheb tuaj yeem qhib tsis pub dhau 2 teev, txo cov kev cuam tshuam txog kev cuam tshuam rau cov tsheb.
Nws yog qhov haum rau txoj kev loj nrog cov tsheb loj sib xyaw, thiab 500 tons ntawm cov sib tov tuaj yeem kis tau ib hnub, nrog kev ua haujlwm zoo nkauj dhau los ntawm kev sib xyaw kub-sib xyaw Asphalt txheej.
Siab txhim kho kev ua tau zoo
Anti-Seem: Lub Macro-qauv qhov txhab yog txhim kho, kev sib txhuam coefficient yog ntau dua, thiab qhov teeb meem ntawm kev nplua kev deb yog hloov kho tau zoo.
Waterproof: lub porosity yog li 5% lossis tsawg dua, sib sau cov txheej txheem ntom ntom los tiv thaiv cov dej saum npoo av los tiv thaiv cov npoo av.
Qhov ruaj khov: Qhov kev pabcuam lub neej yog 5-8 xyoos, thiab Ruts nrog ib qho tob ntawm E≤38mm tuaj yeem kho tau, ncua kev kho dua tshiab ntawm txoj kev sab nraud.
Kev tiv thaiv ib puag ncig thiab kev lag luam
Qhov ntsuas cua sov li qub, tsis muaj cov pa luam yeeb thiab cov pa hluav taws xob thiab cov plua plav, kev siv hluav taws xob muaj ntau dua 50%.
Tus nqi yog 30% -40% qis dua li ntawm kub-mix asphalt, thiab nws tuaj yeem siv ncaj qha hauv kev hnav cov pob zeb tshiab kom txo tau cov pob zeb kim.

2. Siv thev naus laus zis thiab tswj cov ntsiab lus tseem ceeb
Pretricatment ntawm txoj kev qub
Lub RET Kev Kho: CENT5 Ruts yog pua ncaj qha nrog 1cm micro-surfacing; 5-20mm Ruts tau sau ua ob txheej; > 20mm Ruts yuav tsum tau milled thiab leem hauv ntau txheej.
Tiav kev kho:> 5 hli nrib pleb yuav tsum tau ntim nrog grouting; xoob thiab potholes yuav tsum tau khawb thiab sau ua ntej paving.
Kho kom haum:
Yuav tsum tau cov dej ntxuav kom huv: Siv cov dej ntws lossis muaj kev kub siab los ntxuav kom ntseeg tau tias tsis muaj cov khib nyiab lossis dej ntxiv, thiab ua haujlwm tom qab ziab.
Cov Khoom Siv Thiab Sib Txawv Tsim
Kev ua ke: Siv cov pob zeb alkaline xws li basalt thiab dej hiav txwv, nrog cov xuab zeb uas muaj kev sib npaug ≥65% kom ntseeg tau cov admhalt.
Emulsified Asphalt: yuav tsum yog polymer hloov (xws li SBR, SBS), thiab cov muag muag pom kev ntawm cov seem yog ≥.
Sau npe: Caas yog qhov kev nyiam, thiab cov kev siv tshuaj yog txiav txim siab los ntawm kev sim, uas tuaj yeem kho lub sijhawm sib xyaw thiab lub zog ntawm kev sib xyaw.
Kev tsim qauv tsim: Siv cov kev kawm ISSA III kom ntseeg tau tias qhov ua haujlwm ntawm kev sib xyaw thiab kev sib xyaw ntawm cov paving.
Paving thiab sib tswj kev tswj hwm
Paving tuab: xaiv raws li cov tsheb thauj khoom (hnyav tsheb 10mm, nruab nrab 7mm, teeb 3-4mm).
Tsav tsheb ceev: 1.5-3.0km / h, tswj hwm ib qho kev sib txuam no kom tsis txhob muaj kev sib tw tsis sib xws.
Kev kho mob sib koom tes: Cov pob qij qaum sib txuas sib tshooj sib tshooj 4-5m, thiab cov pob qij txha ntev yog nyob ntawm kab cim kom paub tseeb tias Flatness.
Cov khoom yuav tsum tau ua: siv cov pob zeb tsis tu ncua: Siv cov nplais cranter nruab nrog cov v-puab paving trough kom ua tiav cov kev faib tawm ib txwm ua tiav.
Siv tsis:
Saib xyuas thiab qhib
Pib txij nkawm: zam kev braking tam sim ntawd thiab tig tom qab paving. Thaum lub 12.7mm Tick kaw txheej yog siab dua 24 ℃ thiab cov av noo qis dua 50%, nws tuaj yeem tiv thaiv tsheb dov hauv 1 teev.
Thov qhib txhua yam: nyob ntawm seb qhov kub thiab txias thiab ntxuav ntawm qhov sib tov, cov tsheb khiav yog feem ntau qhib tom qab 24 teev.

III. Daim Ntawv Thov Kev Siv thiab Cov Mob
Kev Txhim Kho Cov Ntaub Ntawv Txhim Kho
Cov kev ua yeeb yam los tiv thaiv (sib txhuam coefficient) tau txhim kho los ntawm 30% -50%, thiab cov xwm txheej raug txo los ntawm ntau dua 20%.
Txoj kev ua dej ua ke permeability coefficiess drops rau hauv qab 50ml / min, muaj kev ncua dej zoo.
Tom qab rutting yog sau, lub flatness iri tus nqi yog txo qis rau hauv qab 1.5m / km, thiab tsav tsheb zoo txhim kho.
Nyiaj Txiag Nyiaj Txiag
Tom qab kev sib tw micro tau thov rau txoj kev loj, tus txij nkawm tau raug txo los ntawm 40% nyob rau hauv 5 xyoos, thiab Overhaul lub voj voog tau txuas ntxiv los ntawm 3-5 xyoos.
Piv nrog kub-sib tov Asphalt, tus txij nkawm them rau ib kilometer tau txo los ntawm kwv yees li 200,000 yuan, thiab carbon emissions tau txo los ntawm 60%.
Muaj cov xwm txheej muaj feem xyuam
Kev seem kev nrog cov tsheb loj loj thiab cov feem ntawm cov tsheb thauj khoom hnyav.
Tsis-qauv kev tsis zoo xws li tawg kis me, rutting, thiab kev laus tshwm sim ntawm txoj kev nto.
Cov phiaj xwm kev kub ntxhov kub ceev uas yuav tsum tau kho kom rov qab los ntawm tsheb khiav ceev ceev.
IV. Cov Qauv Txheej Txheem thiab Cov Kev Qhia Tshwj Xeeb
Kev Nyab Xeeb Kev Nyab Xeeb
Qhov kub thaum lub sij hawm tsim kho thiab kho lub sijhawm yog> 10 ℃. Kev tsim kho yog txwv ntawm hnub los nag. Txoj kev saum npoo yuav tsum qhuav tom qab los nag.
Zam kev tsim kho nyob rau hauv lub caij nrog qhov kub tshaj plaws hauv qab 15 ℃ kom ntseeg tau tias qhov zoo ntawm kev solorification.
Txoj Kev Tseem Ceeb Cov Nto Yuav Tsum
Lub zog txheej txheem ua tau raws cov qauv tsim nyog, thiab lub zog tsis txaus thiab xav tau kev txhawb nqa.
Nrib dav> 5 hli yuav tsum tau cog qoob loo, thiab txo cov kev tsis pom zoo yuav tsum tau khawb thiab patched rau txheej ruaj khov.
Cov Qauv Tswj Xyuas Zoo
Sib tov kev ua tau zoo: Lub log ntub dej yuav khoom muaj nqi ≤5,/ m2, thauj cov xuab zeb adhesion ≤450G / M2.
Paving tuab: Tsim tus nqi ± 0.5 hli, flatness txheem sib txawv sib txawv ≤1.2mm.
Qhib kev sim tsheb: Cohesion Testion ≥1.Tus kom ntseeg tau tias interlayer muaj zog.
5. Technology Kev Tsim Kho Kev Loj Hlob
Tsawg-suab nrov micro-surfacing
Los ntawm kev ua tiav cov grading thiab ntxiv cov ntaub ntawv fiber ntau, cov suab nrov tsav tsheb tuaj yeem txo los ntawm 5-8dB, thiab cov kev siv tau ntawm txoj kev loj hauv nroog tuaj yeem hloov kho.
Fiber ntau txhawb nqa Micro-Surfacing
Polyester Fiber ntxiv txhawm rau txhim kho kev kub siab thiab tawg tsis kam, thiab cov kev pabcuam lub neej tuaj yeem txuas ntxiv rau ntau dua 8 xyoo.
Cov Khoom Siv Tsim Kho Zoo
Tsim 3D paving tswj kev tswj hwm kom ua tiav millimeter-qib tuab tswj thiab txo cov khoom siv pov tseg los ntawm 10%-15%.
Tag
Kev tiv thaiv kev tiv thaiv micro-surfacing kev loj tau dhau los ua kev nyab xeeb ntawm txoj kev thiab kev txhim kho kev nyab xeeb ntawm txoj kev ua haujlwm ntawm "nrawm, ib puag ncig kev phooj ywg thiab kev lag luam". Los ntawm nruj me ntsis kev tswj hwm cov khoom siv zoo, siv thev naus laus zis thiab kev tshuaj xyuas zoo, nws cov kev ua tau zoo los muab cov kev daws teeb meem kom muaj kev txhim kho kom muaj kev kho kom muaj kev kho kom zoo.
