Emulsion Bitumen rau Micro Surfacing yog cov khoom siv khi rau Micro Surfacing kev tsim kho. Nws cov yam ntxwv yog tias nws xav tau kom tau raws li lub sijhawm sib xyaw nrog lub pob zeb thiab lub sijhawm qhib rau cov tsheb khiav tom qab kev pua ua tiav. Txhawm rau muab nws yooj yim, nws ua tau ob lub sijhawm teeb meem. Lub sijhawm sib xyaw yuav tsum muaj txaus, thiab kev qhib tsheb yuav tsum tau nrawm, yog txhua yam.
Cia peb tham txog emulsion backumen dua. Emulsion bitumen yog cov roj-hauv-dej bitumen emulsion. Nws yog cov kua paug tsis sib xws ntawm chav sov. Nws tuaj yeem siv txias txias thiab tsis tas yuav muaj cua sov. Nws yog lub zog txuag thiab ib puag ncig phooj ywg. Emulsion Bitumen tau muab faib ua peb hom raws li cov me ntsis bitumenInifiers siv nyob rau hauv kev tsim khoom: Qeeb tawg, nruab nrab tawg. Lub emulsified bitumen siv nyob rau hauv micro-surfacing kev siv yog qeeb tawg thiab ceev teeb cationic emulsion bitumen. Hom emulsion tau npaj siab siv qeeb tawg thiab kev teeb tsa ceev bitumen emulsifier thiab ntxiv polymer modifiers. Nws tuaj yeem ua tiav lub sijhawm sib tov txaus thiab cov nyhuv hloov ceev. Cov nplaum ntawm cations thiab pob zeb yog qhov zoo, yog li cov hom cationic yog xaiv.

Qeeb qeeb tawg thiab nrawm chaw emulsion bitumen yog siv rau kev txij nkawm kev. Ntawd yog, nws yog siv thaum lub hauv paus txheej yog yeej tsis yooj yim tab sis cov txheej saum npoo yog puas, xws li txoj kev ncaj, tawg, rutted, thiab lwm yam.
Kev Tsim Kho Txoj Kev Siv: Tshuaj Tsuag Txheej Txheej Txheem nplaum ua ntej, tom qab ntawd siv micro-surfacing / slurry foob paver mus rau Paver mus rau Paver mus rau Paver mus rau Paver mus rau Paver mus rau Paver mus rau Paver mus rau Paver mus rau Paver mus rau Pave. Thaum thaj chaw me me, phau ntawv sib xyaw thiab cov paving ntawm emulsion bitumen thiab pob zeb yuav siv tau. Leveling yog yuav tsum tau tom qab paving. Nws tuaj yeem siv tau ib txwm tom qab tos rau saum npoo kom qhuav. Muaj feem xyuam rau: nyias txheej kev tsim kho nyob rau hauv 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 cov teeb meem thaum kev tsim kho, koj tuaj yeem tiv toj cov neeg siv kev pabcuam rau kev sab laj!
Qeeb-tawg thiab nrawm nrawm Emulsion Backumen yog cov khoom siv cementing rau slurry sealing thiab micro-deg paving. Nruj me ntsis kev hais lus, hauv kev tsim kho ntawm hloov kho slurry foob thiab micro-surfacing yuav tsum tau muab ntxiv nrog kev hloov kho, uas yog, hloov emulsion emulsion.
