Cov khoom siv cementing siv hauv micro-surfacing yog hloov kho emulsified bitumen. Nws cov yam ntxwv yog dab tsi? Cia peb tham txog txoj kev tsim kho ntawm micro surfacing ua ntej. Micro surfacing siv lub micro surfacing paver kom sib npaug ntawm cov pob zeb, muab tub lim (cement, txiv qaub, thiab lwm yam), hloov kho emulsified bitumen, dej thiab lwm yam khoom ntxiv rau ntawm txoj kev sib faib. Txoj kev tsim kho no muaj qee qhov zoo vim tias cov khoom siv sib txuas siv tau hloov kho qeeb-cracking ceev-teeb emulsified bitumen.
Lub micro-nto muaj zoo dua los tiv thaiv hnav thiab tiv thaiv plam. Piv nrog rau cov slurry sealants zoo tib yam, qhov saum npoo ntawm micro-surface muaj ib qho kev ntxhib los mos, uas tuaj yeem tiv taus kev sib txhuam ntawm lub tsheb thiab kev nplua thiab ua kom muaj kev nyab xeeb ntawm kev tsav tsheb. Lub hauv paus rau lub ntsiab lus no yog tias cov cement siv hauv micro-surfacing yuav tsum muaj cov khoom sib txuas zoo.
Tom qab ntxiv cov kev hloov kho rau cov emulsified bitumen zoo tib yam, cov khoom ntawm cov bitumen tau txhim kho, thiab kev sib koom ua ke ntawm micro-nto zoo tuaj. Qhov no ua rau txoj kev ntog tom qab kev tsim kho tau zoo dua durability. Txhim kho kev ua haujlwm siab thiab qis qis ntawm txoj kev pavement.
Lwm qhov tseem ceeb ntawm kev hloov kho qeeb-tawg thiab ceev-teeb emulsified bitumen siv hauv micro-surfacing kev tsim kho yog tias nws tuaj yeem tsim kho tshuab lossis manually. Vim nws cov yam ntxwv demulsification qeeb, nws ua tau raws li cov kev xav tau ntawm cov khoom sib tov. Qhov no ua rau kev tsim kho tau yooj yim, thiab txoj kev tsim kho tsim nyog tuaj yeem raug xaiv raws li qhov xwm txheej tiag tiag, tso cai rau cov phiaj xwm paving kom tiav.
Tsis tas li ntawd, cov khoom siv cementing ntawm micro nto kuj muaj cov yam ntxwv ntawm kev teeb tsa ceev. Cov yam ntxwv no tso cai rau txoj kev qhib rau kev khiav tsheb 1-2 teev tom qab kev tsim kho, txo qhov cuam tshuam ntawm kev tsim kho tsheb.
Lwm qhov taw qhia yog tias cov khoom sib txuas siv hauv kev tsim kho micro-surfacing yog kua ntawm chav tsev kub thiab tsis xav tau cua sov, yog li nws yog ib qho kev tsim kho txias. Qhov no tsis tsuas yog txhim kho kev tsim kho kom zoo, tab sis kuj txo qis kev siv hluav taws xob, uas yog raws li lub tswv yim ntawm kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig. Piv nrog rau cov tsoos kub bitumen kev tsim kho, txoj kev tsim kho txias ntawm micro-surfacing tsis tsim cov pa phem thiab tsis tshua muaj kev cuam tshuam rau ib puag ncig thiab cov neeg ua haujlwm tsim kho.
Cov yam ntxwv no yog qhov yuav tsum tau ua ua ntej txhawm rau ua kom muaj txiaj ntsig kev tsim kho thiab tseem yog cov yam ntxwv tsim nyog. Puas yog emulsified bitumen koj yuav muaj cov khoom no?
