Slurry sealing originated nyob rau hauv lub teb chaws Yelemees thiab muaj keeb kwm ntawm ntau tshaj 90 xyoo. Slurry seals muaj ntau yam kev siv thiab tseem tuaj yeem siv rau kev kho tsheb loj. Vim tias nws muaj qhov zoo ntawm kev txuag hluav taws xob, txo kev ua qias tuaj ib puag ncig thiab txuas ntxiv lub caij tsim kho, nws tau txais kev txhawb nqa los ntawm cov kws tshaj lij txoj kev loj thiab cov neeg ua haujlwm tu. Slurry sealing txheej yog tsim los ntawm cov pob zeb uas tsim nyog los yog cov xuab zeb, cov khoom siv (cement, txiv qaub, ya tshauv, pob zeb hmoov, thiab lwm yam), emulsified asphalt, sab nraud admixtures thiab dej, uas yog tov rau hauv ib tug slurry nyob rau hauv ib tug tej yam kev faib ua feem thiab kis tau A pavement qauv uas ua hauj lwm raws li ib tug foob tom qab paving, hardened, thiab tsim. Vim tias qhov sib xws ntawm cov slurry sib tov yog nyias thiab cov duab zoo li slurry, cov paving thickness feem ntau yog nyob nruab nrab ntawm 3-10mm, thiab nws tsuas yog ua lub luag haujlwm ntawm cov dej tsis zoo los yog kev txhim kho thiab kho cov pavement muaj nuj nqi. Nrog rau txoj kev loj hlob sai ntawm polymer-hloov asphalt slurry foob tau tshwm sim.

Lub slurry foob muaj cov haujlwm hauv qab no:
1. Waterproofing
Lub aggregate particle loj ntawm cov slurry sib tov yog kuj zoo thiab muaj ib tug tej yam gradation. Cov emulsified asphalt slurry sib tov yog tsim tom qab pavement yog paving. Nws tuaj yeem ua raws txoj kev nyob rau hauv txoj kev saum npoo av los ua cov txheej los nag, uas tuaj yeem tiv thaiv cov txheej los ntawm lub hauv paus txheej thiab tswj hwm qhov ruaj khov ntawm lub hauv paus txheej thiab av puag:
2. Anti-slip nyhuv
Txij li cov paving thickness ntawm emulsified asphalt slurry sib tov yog nyias, thiab cov ntaub ntawv ntxhib nyob rau hauv nws gradation yog tusyees faib, thiab tus nqi ntawm asphalt yog tsim nyog, qhov tshwm sim ntawm cov roj dej nyab ntawm txoj kev yuav tsis tshwm sim. Txoj kev saum npoo av muaj qhov ntxhib zoo. Kev sib txhuam coefficient yog nce ntxiv, thiab kev ua haujlwm tiv thaiv kev ua haujlwm tau zoo dua qub.
3. Hnav tsis kam
Cationic emulsified asphalt muaj adhesion zoo rau ob qho tib si acidic thiab alkaline ntxhia cov ntaub ntawv. Yog li ntawd, cov slurry sib tov tuaj yeem ua los ntawm cov khoom siv ntxhia zoo uas nyuaj rau hnav thiab zom, yog li nws tuaj yeem tau txais kev hnav zoo thiab ua kom ntev kev pab cuam lub neej ntawm txoj kev.
4. filling nyhuv
Cov emulsified asphalt slurry sib tov muaj dej ntau, thiab tom qab sib tov, nws yog nyob rau hauv ib lub xeev slurry thiab muaj fluidity zoo. Qhov no slurry muaj ib tug filling thiab leveling nyhuv. Nws tuaj yeem nres qhov tawg me me ntawm txoj kev nto thiab txoj kev tsis sib xws uas tshwm sim los ntawm kev xoob thiab ntog ntawm txoj kev. Cov slurry tuaj yeem siv los kaw cov kab nrib pleb thiab sau cov qhov ntiav ntiav kom txhim kho txoj kev du ntawm txoj kev.
Qhov zoo ntawm slurry seal:
1. Nws muaj kev hnav zoo dua, kev ua haujlwm tsis zoo, thiab muaj zog adhesion rau hauv qab txheej;
2. Nws tuaj yeem txuas lub neej ntawm txoj kev thiab txo cov nqi kho kom zoo;
3. Kev tsim kho ceev nrawm dua thiab muaj kev cuam tshuam tsawg rau kev khiav tsheb;
4. Ua haujlwm ntawm qhov kub thiab txias, huv si thiab ib puag ncig zoo.

Cov thev naus laus zis tseem ceeb rau kev siv slurry sealing:
1. Cov ntaub ntawv ua tau raws li cov kev cai. Cov aggregate yog ib qho nyuaj, gradation yog tsim nyog, hom emulsifier yog tsim nyog, thiab slurry sib xws yog nruab nrab.
2. Lub tshuab sealing muaj cov cuab yeej siv siab heev thiab kev ua haujlwm ruaj khov.
3. Txoj kev qub yuav tsum muaj lub zog tag nrho ntawm txoj kev qub raws li qhov yuav tsum tau ua. Cov cheeb tsam uas tsis muaj zog txaus yuav tsum tau ntxiv dag zog. Cov pits thiab tawg loj yuav tsum tau khawb thiab kho. Cov bales thiab washboards yuav tsum tau milled. Cov kab nrib pleb loj dua 3 hli yuav tsum tau sau ua ntej. Txoj kev yuav tsum tau muab tshem tawm.
4. Kev tswj xyuas tsheb. nruj nreem txiav tawm kev khiav tsheb kom tsis txhob tsav tsheb ntawm lub slurry foob ua ntej nws solidifies.
