Tam sim no, feem ntau txoj kev yog paving nrog asphalt, uas muaj ntau yam zoo thiab muaj txiaj ntsig zoo dua li txoj kev cement. Yog li ntawd, ntau lub tsheb tshwj xeeb rau paving asphalt tau muab los pab rau kev paving thiab tu txoj kev. Lub emulsified asphalt slurry sealing tshuab yog ib qho ntawm txoj kev asphalt thev naus laus zis, thiab cov slurry sealing lub luag haujlwm rau kev tsim kho tshwj xeeb txo qhov nyuaj ntawm kev siv cov tshuab no.

Lub emulsified asphalt slurry sealing tsheb yog ib yam khoom tshwj xeeb rau slurry sealing siv. Nws sib tov thiab sib xyaw ntau yam khoom siv xws li cov khoom siv ntxhia tsim nyog, cov khoom ua kom zoo, asphalt emulsion thiab dej raws li ib qho qauv tsim los ua ib lub tshuab uas tsim cov slurry sib tov sib xyaw thiab nthuav tawm ntawm txoj kev raws li qhov xav tau tuab thiab dav. Cov txheej txheem ua haujlwm yog ua tiav los ntawm kev sib xyaw ua ke, sib xyaw thiab paving thaum lub tsheb sib khi mus ncig. Nws tus yam ntxwv yog tias nws yog tov thiab paved ntawm txoj kev nto ntawm qhov kub thiab txias. Yog li ntawd, nws tuaj yeem txo qis kev siv zog ntawm cov neeg ua haujlwm, ua kom cov kev tsim kho kom zoo, txuag cov peev txheej thiab txuag hluav taws xob.
Qhov zoo ntawm slurry sealing tshuab: Emulsified asphalt slurry sealing txheej yog cov slurry sib xyaw ua los ntawm cov khoom siv ntxhia zoo, emulsified asphalt, dej, fillers, thiab lwm yam, sib xyaw hauv ib qho kev faib ua feem. Raws li qhov tshwj xeeb thickness (3-10mm) yog sib npaug ntawm txoj kev nto los tsim ib txheej nyias ntawm asphalt nto kho. Tom qab demulsification, pib qhov chaw, thiab solidification, cov tsos thiab kev ua haujlwm zoo ib yam li cov txheej saum toj kawg nkaus ntawm cov nplua-grained asphalt pob zeb. Nws muaj qhov zoo ntawm kev tsim kho yooj yim thiab ceev, tus nqi qis ntawm qhov project, thiab kev tsim kho hauv nroog tsis cuam tshuam rau kev tso dej, thiab kev tsim kho choj choj muaj qhov hnyav tsawg.
Lub luag haujlwm ntawm slurry sealing txheej yog:
l. Waterproof: Cov slurry sib tov adheres rau txoj kev nto los ua ib tug tuab txheej txheej, uas tiv thaiv los nag thiab daus los ntawm nkag mus rau hauv lub hauv paus txheej.
2. Anti-skid: Lub paving thickness yog nyias, thiab cov coarse aggregate yog tusyees faib rau ntawm qhov chaw los tsim ib tug zoo ntxhib nto, uas txhim kho cov anti-skid kev ua tau zoo.
3. Hnav tsis kam: Hloov cov slurry foob / micro-surfacing tsim zoo heev txhim kho qhov adhesion ntawm emulsion thiab pob zeb, anti-flaking, high-temperature stability, thiab low-temperature shrinkage cracking resistance, extending the service life of the pavement. .
4. Filling: Tom qab sib tov, cov sib tov yuav nyob rau hauv ib lub xeev slurry nrog zoo fluidity, uas plays ib tug tej yam lub luag hauj lwm nyob rau hauv sau cov kab nrib pleb thiab leveling txoj kev nto.
