Kev tsim kho zaum kawg ntawmEmulsified asphalt kuamuaj kev sib raug zoo nrog rau qhov chaw ib puag ncig. Qhov zoo ib puag ncig txhawb kev ruaj khov emulsification cov tshuaj tiv thaiv thiab cov txheej txheem demulsification-kho, thaum cov xwm txheej hnyav ncaj qha coj mus rau qhov tsis xws ntawm pavement thiab cov khoom pov tseg. Yog li ntawd, qhov chaw kub, huab cua, hauv av thiab qhov cua yuav tsum tau ua tib zoo xyuas ua ntej kev tsim kho kom haum rau cov yam ntxwv ntawm Emulsified Asphalt Liquid. Ambient kub sawv cev rau qhov tseem ceeb ntawm kev tsim kho kom zoo. Emulsification, demulsification, bonding thiab kho ntawm Emulsified Asphalt Liquid cia siab rau qhov tsim nyog thermal tej yam kev mob. Nyob rau hauv qhov zoo ntawm qhov kub thiab txias ntawm 10℃-35 degree, cov khoom lag luam nce mus txog nws qhov siab tshaj plaws, demulsification ua tau zoo sib xws thiab cov txiaj ntsig zoo sib xws ua tiav.
Thaum ambient kub poob qis dua 10 degree, kev ua haujlwm molecular ntawm Emulsified Asphalt kua txo qis, demulsification thiab kho qeeb heev. Tshiab nteg pavements tsis ua kom ruaj khov rau lub sijhawm ntev, yooj yim nqus plua plav thiab cov khoom txawv teb chaws, uas tom qab ntawd ua rau pavement loosening thiab tsis muaj zog sib txuas. Kev khov thiab stratification ntawm emulsion kuj tseem tuaj yeem tshwm sim nyob rau hauv qhov kub thiab txias, ua rau cov ntaub ntawv siv tsis tau kiag li. Yog tias ambient kub tshaj 35 degree, tom qab Emulsified Asphalt Liquid yog txau los yog txhuam, dej evaporates sai heev, ua rau kom sai demulsification thiab tsis sib xws hauv zos ziab. Qhov no ua rau cov txheej txheej tsis sib xws ntawm cov pavements thiab cov adhesion tsis zoo, ua raws li kev tawg thiab tev tawm tom qab lub sijhawm ua haujlwm.
Tom ntej no, kev tsim kho yuav tsum zam kom tsis txhob muaj kev cuam tshuam rau huab cua phem. Tsis txhob ua kev tsim kho rau hnub los nag lossis ua ntej pavements qhuav kom huv si tom qab los nag. Sawv ntsug dej ntawm pavements dilutes Emulsified Asphalt kua concentration thiab puas emulsion systems, tiv thaiv asphalt los ntawm kev sib raug zoo nrog puag txheej thiab ua rau sai tev tom qab kev tsim kho. Kev ua haujlwm tsis raug pom zoo nyob rau hauv cov xwm txheej gae ntawm cua-ceev zog 5 lossis siab dua. Cov cua muaj zog cua tshuab tshem tawm los yog txhuam emulsified Asphalt Liquid, nkim raw khoom, thiab nqa ntau cov xuab zeb plua plav mus rau qhov chaw uas tsis muaj kev kho mob los tsim cov interlayers thiab ua rau cov pavement ruaj khov. Kev tsim kho kuj tseem yuav tsum tau nres hauv huab cua hnyav thiab Frost, rau cov dej noo ntau dhau los kho thiab degrades ua kom zoo.
Tsis tas li ntawd, kev ua haujlwm hauv av yuav tsum ua raws li cov qauv. Cov chaw ua haujlwm yuav tsum nyob twj ywm huv, qhuav thiab qib, tsis muaj sludge, roj paug, pob zeb khib nyiab thiab cov plua plav ntab. Cov roj stains cais Emulsified Asphalt Liquid los ntawm cov kev kawm hauv paus thiab txo kev sib koom ua ke, thaum cov khoom txawv teb chaws ua rau cov khoom tsis sib xws, hollowing thiab cracking tom qab kev tsim pavement. Nyob ib puag ncig thaj chaw tsim kho yuav tsum ua kom zoo kom tsis txhob muaj kev sib kis ntawm cov chaw ua haujlwm los ntawm cov khib nyiab thiab cov plua plav ya. Kev ua pa txaus yuav tsum tau khaws cia ntawm qhov chaw tsim kho; ntuj cua sab nraum zoov txaus. Tsis txhob ua kev tsim kho hauv qab daus lossis qhov chaw nqaim kaw, qhov twg cov khoom tsis haum ntawm cov emulsion sib sau ua ke thiab cuam tshuam nrog kev ua haujlwm ntawm phau ntawv thiab cuam tshuam cov txheej txheej kom qhuav thiab khov.
Tsis tas li ntawd, kev tsim kho yuav tsum tau khaws cia kom deb ntawm qhov chaw nyob ib puag ncig, xws li cov chaw uas muaj hnub ci ci ntsa iab uas tsis muaj chaw nyob thiab thaj chaw qis qis uas muaj huab cua tsis zoo. Tshawb xyuas cov xwm txheej ntawm qhov chaw ua ntej ntawm kev tsim kho, tshem cov khib nyiab thiab dej sawv ntawm qhov chaw ua haujlwm, thiab npaj cov sijhawm tsim kho raws li huab cua huab cua. Ua ntej kev tsim kho hauv lub caij nplooj ntoos hlav me me thiab lub caij nplooj zeeg. Tsis txhob nruab hnub kub kub thaum lub caij ntuj sov thiab xaiv lub sijhawm sov so rau lub caij ntuj no. Tag nrho cov kev ntsuas no muaj kev ruaj ntseg zoo tsim kev ua tau zoo ntawm Emulsified Asphalt Liquid thiab pab kom muaj ntau yam teeb meem pavement-zoo ntawm bay.
