Emulsified asphalt yog ib qho kev emultion abulsion nyob rau hauv cov roj-hauv-dej lub xeev. Nws yog ib qho kev sib txawv ntawm cov kua uas muaj kuab thiab muaj cov yam ntxwv ntawm kev tsim kho txias, tsis xav tau cua sov, kev tiv thaiv hluav taws xob thiab kev txuag ib puag ncig. Emulsified asphalt tau faib ua peb hom raws li txawv li aspultifiers eurulsifiers emulsfiers emboring, qeeb tawg thiab nrawm tawg. Lub emulsified asphalt siv nyob rau hauv micro-surfacing kev tsim kho yog bCulsified asphalt. Cationic emulsified asphalt muaj adhesion zoo rau pob zeb. Kev tsim kho micro kev siv hluav taws xob yuav tsum tau sib xyaw. Lub emulsified asphalt siv lub cationic qeeb-tawg thiab nrawm
Qeeb qeeb thiab nrawm nrawm Emulsified yog, thaum pib txheej, xws li tus txheej txheem du, xws li cov txheej txheem du, tawg, rutted, thiab pockmarked surfaces ntawm txoj kev nto.
5 txoj hauv kev los txhim kho kev tsim khoom ntawm txoj kev siv tshuab ua tshuab
Txoj kev tsim qauv yog raws li hauv qab no:
1. Txau txheej txheej txheej txheem roj ua ntej, thiab tom qab ntawd siv micro-surfacing / slurry foob paver rau paver.
2. Yog tias thaj chaw no yog qhov me me, koj tuaj yeem siv phau ntawv sib xyaw thiab paving ntawm emulsified asshalt thiab pob zeb.
3. Tom qab paving, txhuam nws tiaj tus thiab tos rau saum npoo kom qhuav ua ntej kev tsav tsheb qub.
Nws yuav tsum raug sau tseg tias qeeb-tawg thiab ceev-teeb tsa emulsified asphalt yog qhov tsim nyog rau nyias txheej txheej tsis pub dhau 1 cm. Yog tias cov tuab yuav tsum tau tshaj 1 cm, nws yuav tsum tau pua hauv txheej. Tom qab ib txheej yog qhuav, txheej tom ntej tuaj yeem raug pua. Yog tias muaj teeb meem thaum lub chaw tsim khoom, koj tuaj yeem hu rau cov neeg siv kev pabcuam rau kev sab laj.
Nyob rau hauv luv luv, emulsified asphalt, uas yog ib qho tshwj xeeb ecountion emulsion, muaj ntau cov ntawv thov kev cia siab. Hais txog ntawm kev txij nkawm, nws tuaj yeem txhim kho kev pabcuam lub neej thiab kev tawm tsam ntawm txoj kev saum npoo thiab txo tus nqi ntawm kev saib xyuas kev. Nyob rau tib lub sijhawm, emulsified asphalt kuj muaj qhov zoo ntawm kev tiv thaiv ib puag ncig thiab txuag hluav taws xob, uas yog nyob rau hauv txoj kab kev txhim kho tam sim no ntawm kev txhim kho hauv zej zog.
