Slurry foob yog siv cov cuab yeej siv tshuab los sib xyaw kom haum rau qib emulsified asphalt, ntxhib thiab nplua aggregates, dej, fillers (cement, txiv qaub, ya tshauv, pob zeb hmoov, thiab lwm yam) thiab additives rau hauv slurry sib tov raws li tus qauv tsim piv thiab sib npaug sib npaug. nws nyob ntawm txoj kev qub. Tom qab qhwv, demulsification, dej sib cais, evaporation thiab solidification, nws yog ruaj khov ua ke nrog cov thawj txoj kev nto los ua ib tug ntom, muaj zog, hnav-resistant thiab txoj kev nto foob, uas zoo heev txhim kho kev ua tau zoo ntawm txoj kev nto.
Slurry foob tshuab tau tshwm sim hauv Tebchaws Yelemees thaum xyoo 1940s. Hauv Tebchaws Meskas, daim ntawv thov slurry foob suav txog 60% ntawm lub teb chaws txoj kev dub, thiab nws txoj kev siv tau nthuav dav. Nws ua lub luag haujlwm tiv thaiv thiab kho cov kab mob xws li kev laus, tawg, smoothness, looseness, thiab potholes ntawm txoj kev tshiab thiab qub, ua rau txoj kev tsis muaj dej tsis zoo, tiv thaiv kev nplua, tiaj tus, thiab hnav-tiv taus sai sai.

Slurry foob kuj yog ib qho kev tiv thaiv kev tsim kho kev tsim kho rau saum npoo av. Qub asphalt pavements feem ntau muaj cov kab nrib pleb thiab cov poholes. Thaum lub saum npoo yog hnav, ib qho emulsified asphalt slurry foob sib tov yog kis mus rau hauv ib txheej nyias ntawm pavement thiab solidified sai li sai tau kom tswj tau cov asphalt qhob pavement. Nws yog kev saib xyuas thiab kho lub hom phiaj ntawm kev rov ua haujlwm ntawm txoj kev pavement kom tsis txhob muaj kev puas tsuaj ntxiv.
Qhov qeeb-kawg lossis nruab nrab-kawg sib xyaw emulsified asphalt siv hauv slurry foob yuav tsum muaj asphalt lossis polymer asphalt cov ntsiab lus ntawm li 60%, thiab qhov tsawg kawg nkaus yuav tsum tsis pub tsawg dua 55%. Feem ntau, anionic emulsified asphalt tsis zoo adhesion rau cov ntaub ntawv ntxhia thiab lub sijhawm molding ntev, thiab feem ntau yog siv rau alkaline aggregates, xws li limestone. Cationic emulsified asphalt tau zoo adhesion rau acidic aggregates thiab feem ntau yog siv rau acidic aggregates, xws li basalt, granite, thiab lwm yam.
Kev xaiv ntawm asphalt emulsifier, ib qho ntawm cov khoom xyaw hauv emulsified asphalt, yog qhov tseem ceeb tshwj xeeb. Ib qho zoo asphalt emulsifier tuaj yeem tsis tsuas yog ua kom zoo ntawm kev tsim kho tab sis kuj txuag nqi. Thaum xaiv, koj tuaj yeem xa mus rau ntau qhov ntsuas ntawm asphalt emulsifiers thiab cov lus qhia rau kev siv cov khoom sib xws. Peb lub tuam txhab tsim ntau yam ntau hom asphalt emulsifiers. Yog tias koj muaj lus nug, thov sab laj nrog peb cov neeg siv khoom.
Emulsified asphalt slurry foob tuaj yeem siv rau kev tiv thaiv kev saib xyuas ntawm txoj kev theem nrab thiab qis qis, thiab tseem tsim nyog rau kev foob qis, hnav txheej lossis txheej tiv thaiv ntawm txoj kev loj uas nyuam qhuav tsim. Tam sim no nws kuj tseem siv rau txoj kev loj.
Classification ntawm slurry seal:
Raws li qhov sib txawv ntawm cov khoom siv ntxhia, slurry foob tuaj yeem muab faib ua cov foob zoo, nruab nrab foob thiab ntxhib foob, sawv cev los ntawm ES-1, ES-2 thiab ES-3 raws li.
Raws li qhov ceev ntawm kev qhib tsheb
Raws li kev ceev ntawm kev qhib tsheb [1], slurry foob tuaj yeem muab faib ua nrawm nrawm hom slurry foob thiab qeeb qhib tsheb hom slurry foob.
Raws li seb puas muaj cov hloov pauv polymer ntxiv
Raws li seb puas muaj kev hloov pauv polymer ntxiv, slurry foob tuaj yeem muab faib ua slurry foob thiab hloov slurry foob.
Raws li cov khoom sib txawv ntawm emulsified asphalt
Raws li cov khoom sib txawv ntawm emulsified asphalt, slurry foob tuaj yeem muab faib ua cov slurry zoo tib yam thiab hloov slurry foob.
Raws li qhov tuab, nws tuaj yeem muab faib ua cov txheej txheej zoo sealing (txheej I), nruab nrab sealing txheej (hom II), coarse sealing txheej (hom III) thiab thickened sealing txheej (hom IV).
