Yuav ntev npaum li cas peb yuav tsum tos ua ntej qhib tsheb tom qab Emulsified asphalt kua siv?

Tsis muaj universal taag sijhawm tos rau kev qhib tsheb tom qabEmulsified asphalt kuakev tsim kho. Lub sijhawm tos tiag tiag yog txiav txim siab los ntawm qhov chaw nyob qhov kub thiab txias, av noo, huab cua puag, siv txheej tuab thiab cov khoom siv ntawm Emulsified Asphalt Liquid. Kev kho tus nqi sib txawv heev nyob rau hauv cov kev ua haujlwm sib txawv, yog li lub sijhawm qhib tsheb yuav tsum raug txiav txim raws li qhov xwm txheej ntawm lub ntiaj teb tiag tiag es tsis yog cov qauv sib koom ua ke. Kev nkag mus ua ntej ua ntej ua rau pavement sticking, sanding, tev thiab deformation thiab tag nrho cov khoom tsim tawm. Raws li tus qauv zoo tshaj plaws ua haujlwm nrog qhov ntsuas kub ntawm 15℃txog 30 degree, huab cua tshav ntuj, qhov cua zoo thiab cov av noo nyob nruab nrab, kev kho mob ua haujlwm tsis tu ncua rau cov pavements tiav nrog nyias txheej txau lossis txhuam emulsified asphalt kua.
Ib mus rau ob teev tom qab kev tsim kho yog qhov pib ntawm qhov chaw teeb tsa. Nyob rau theem no, cov emulsion tiav ua ntej demulsification thiab cov dej saum npoo evaporates maj mam, tab sis cov qauv sab hauv tseem tsis tau kho nrog cov nplaum pavement. Tsis pub neeg taug kev lossis tsheb trampling lossis dov. Ob mus rau plaub teev tom qab kev tsim kho, cov txheej txheej saum npoo qhuav kom huv si yam tsis muaj qhov nplaum, thiab cov txheej txheem sab hauv yuav zoo li qub. Cov neeg taug kev tuaj yeem taug kev maj mam ntawm cov pavements, txawm hais tias lub tsheb hluav taws xob thiab tsheb tsav tsheb tseem raug txwv. Tom qab 6 mus rau yim teev, cov pavements ua kom tiav tag nrho nrog kev sib koom ua ke ntawm lub zog thiab compactness, yog li cov tsheb me me tuaj yeem hla tau ib txwm. Nees nkaum plaub teev tom qab kev tsim kho, txhua hom tsheb raug tso cai mus ncig, thiab cov chaw pavement ncav cuag qhov zoo tshaj plaws.
Lub sijhawm tos tsheb khiav yuav tsum tau ncua ntev heev nyob rau hauv qhov kub thiab txias. Thaum ambient kub poob qis dua 10 degree, los yog nyob rau hauv rainy-humid huab cua nrog tsis zoo qhov chaw qhov cua, dej evaporation los ntawm Emulsified Asphalt Liquid slows sharply thiab demulsification-kho cov txheej txheem yuav qeeb heev. Qhov chaw pib qhov chaw yuav siv sijhawm plaub mus rau rau teev, kev nkag mus rau cov neeg taug kev tau tso cai tom qab yim mus rau kaum teev, thiab kev rov qhib lub tsheb yuav tsum tau ncua mus rau 12-24 teev. Rau kev tsim kho ua tiav nyob rau hauv cov xwm txheej tom qab los nag qis hauv qhov chaw ntub dej, qhov chaw zoo li qub yuav tsum tau muab tso rau ntau tshaj 24 teev rau kev kho kom zoo. Kev khiav tsheb tsuas tuaj yeem rov pib dua tom qab cov pavements tig tag nrho qhuav thiab tsis nplaum.
Lub sijhawm qhib tsheb tuaj yeem ua kom luv luv kom tsim nyog nyob rau hauv cov xwm txheej kub qhuav. Nyob rau lub caij ntuj sov nrog kub siab tshaj 30 degree, txaus qhov cua thiab cua qhuav, dej evaporates sai heev thiab demulsification-kho efficiency txhim kho zoo kawg li. Cov khaubncaws sab nraud povtseg qhuav li ntawm ib mus rau ob teev tom qab kev tsim kho, cov neeg taug kev thiab cov tsheb me me tuaj yeem hla tom qab peb mus rau plaub teev, thiab cov tsheb khiav tsis tu ncua hauv plaub mus rau rau teev. Nws yog ib qho tsim nyog sau cia tias cov pavements tau nrawm nrawm nrawm tab sis qeeb hauv kev ua kom khov nyob rau hauv huab cua thaum nruab nrab lub caij ntuj sov. Kev txiav txim rau lub sijhawm qhib kev tsheb tsuas yog raws li qhov tshwm sim ntawm qhov chaw yuav tsum zam, thiab lub sijhawm tsis tuaj yeem raug txwv kom tsis txhob muaj cov pavement sab hauv uas tsis tau kho los ntawm kev puas tsuaj nyob rau hauv compression loads.
Txheej tuab kuj cuam tshuam rau lub sijhawm qhib tsheb. Thin-layer tack-coat thiab deservation tsim kho kom paub sai sai thiab ua raws li lub sijhawm tos tsis tu ncua. Thick-layer paving slows internal volatilization thiab prolongs curing cycles los ntawm peb mus rau tsib teev tag nrho. Hloov chaw ntawm kev suav cov sijhawm ncua sijhawm, cov xwm txheej ntawm lub cev pavement yog cov txheej txheem txiav txim siab rau kev rov qhib tsheb. Kev khiav tsheb tuaj yeem qhib tau thaum cov pavement qhuav tag, tsis nplaum, tsis muaj xuab zeb xoob thiab tag nrho cov tawv tawv. Kho lub sijhawm tos kom hloov tau yooj yim hauv kev tsim kho raws li huab cua, kub thiab txheej txheej kom tsis txhob muaj qhov tsis xws luag uas tshwm sim los ntawm kev qhib tsheb khiav ntxov ntxov thiab txuas ntxiv kev pabcuam pavement.
