Nrog rau kev loj hlob sai ntawm peb lub teb chaws kev lag luam thiab thev naus laus zis, peb lub teb chaws txoj kev tsheb thauj mus los kuj tau txhim kho zoo heev. Txawm li cas los xij, lub peev xwm thauj khoom ntawm lub tsheb kuj tseem nce nrawm, thiab cov tsheb loj loj kuj tseem nce ntxiv, uas tau ua rau muaj kev cuam tshuam loj rau kev thauj mus los. Yog li ntawd, txoj kev loj Txoj kev txij nkawm ua haujlwm tau maj mam nyiam cov neeg nyiam.
Txoj kev pavement ntawm txoj kev loj ib txwm siv cov khoom siv asphalt zoo tib yam, uas yog deb ntawm kev ua tau raws li cov qauv siab thiab cov kev cai ntawm kev thauj mus los niaj hnub rau kev loj. Yuav ua li cas npaj high-qib pavement asphalt binder los xyuas kom meej qhov zoo thiab efficiency ntawm kev loj siv yog ib lo lus nug tsim nyog tshawb nrhiav. Slurry sealing thiab micro-surfacing thev naus laus zis tau maj mam txhawb nqa raws li kev tiv thaiv kev saib xyuas nrog cov khoom zoo thiab kev lag luam.
Qhov sib xyaw ntawm emulsified asphalt slurry sib tov yog qhov nyuaj, feem ntau suav nrog cov cement, ya tshauv, ntxhia hmoov thiab additives. Cov slurry sib tov siv pob zeb los yog xuab zeb raws li qhov yooj yim aggregate, tab sis kev xaiv ntawm pob zeb thiab xuab zeb tsis yog arbitrary, tab sis yuav tsum tau mus txog ib tug tej yam gradation, thiab ces ntxiv ib co kev faib ua feem ntawm emulsified asphalt raws li ib tug binding khoom kom ua tau ib tug binding nyhuv. Yog tias qhov xwm txheej tshwj xeeb, koj tuaj yeem xaiv ntxiv ib feem ntawm cov hmoov. Tom qab tag nrho cov khoom xyaw ntxiv, lawv tau tov nrog dej hauv ib qho kev faib ua feem los tsim cov asphalt sib tov. Kev sib xyaw asphalt tsim los ntawm cov khoom siv no yog cov kua dej thiab yooj yim siv thaum tu txoj kev. Cov sib tov yog txau rau ntawm txoj kev nto los ntawm lub slurry sealing tsheb los tsim ib lub slurry foob. Cov ntsiab lus tseem ceeb ntawm kev txau yog tas mus li thiab sib xws. Qhov sib tov ua ib txheej nyias ntawm asphalt nto kho ntawm txoj kev nto, uas yog qhov zoo rau cov txheej txheem tom ntej. Lub luag haujlwm tseem ceeb ntawm cov txheej nyias nyias no yog los tiv thaiv qhov chaw ntawm txoj kev qub thiab ua rau txoj kev hnav qeeb.
Vim yog kev koom ua ke ntawm ib qho kev faib ua feem ntawm cov dej rau hauv slurry sealing sib tov, nws yooj yim rau evaporate hauv huab cua. Tom qab cov dej evaporated, nws yuav qhuav thiab tawv. Yog li ntawd, tom qab lub slurry yog tsim, nws tsis tsuas zoo nkaus li zoo-grained asphalt pob zeb, tab sis tsis cuam tshuam rau qhov pom kev ntawm txoj kev. Nws kuj tseem muaj cov khoom siv zoo ib yam li cov pob zeb zoo nkauj hauv cov ntsiab lus ntawm kev hnav tsis kam, tiv thaiv kev nplua, dej tsis qab, thiab smoothness. Slurry foob tshuab yog siv rau hauv kev loj txoj kev pavement txij nkawm vim nws txoj kev siv tshuab yooj yim, siv sij hawm luv luv, tsis tshua muaj nqi, zoo siab, dav daim ntawv thov, muaj zog adaptability, thiab lwm yam. Nws yog ib qho kev siv nyiaj txiag thiab siv tau zoo. Asphalt pavement tu tshuab yog tsim nyog rau daim ntawv thov thiab nce qib. Tsis tas li ntawd, qhov zoo ntawm cov thev naus laus zis no kuj tseem cuam tshuam nrog kev sib koom ua ke siab ntawm cov ntaub ntawv asphalt thiab cov ntxhia, muaj zog ua ke nrog txoj kev nto, muaj peev xwm los npog tag nrho cov ntaub ntawv ntxhia, muaj zog thiab ua haujlwm zoo.
