Tam sim no, feem ntau txoj kev yog pua nrog asphalt, uas muaj ntau yam zoo thiab yog qhov zoo dua txoj kev xiss. Yog li no ntau lub tsheb tshwj xeeb rau paving asphalt tau muab fij tau los pab hauv paving thiab saib xyuas txoj kev. Lub emulsified asphalt slurry seeding tshuab yog ib qho ntawm cov kev siv roj asphalt rau cov kev tsim kho kom zoo rau kev siv cov thev naus laus zis.

Lub emulsified asphalt slurry sealing tsheb yog cov khoom siv tshwj xeeb rau slurry sealing siv. Nws sib xyaw thiab sib tov ntau cov ntaub ntawv raw xws li cov ntaub ntawv me me kom ua rau cov khoom siv uas tsim tau zoo thiab muab cov khoom tsim los ntawm txoj kev raws li qhov uas yuav tsum tau dav thiab dav. Cov txheej txheem ua haujlwm tiav los ntawm kev sib txuas tsis tu ncua, sib xyaw thiab paving thaum lub tsheb sib khi yog taug kev. Nws cov yam ntxwv yog tias nws yog sib xyaw thiab pua ntawm txoj kev saum npoo ntawm qhov kub ib txwm muaj. Yog li ntawd, nws tuaj yeem txo qis kev siv zog ntawm cov neeg ua haujlwm, ceev cov kev siv kev tsim kho, txuag cov khoom siv thiab txuag lub zog.
Cov txiaj ntsig zoo ntawm slurry sealing thev naus laus zis: emulsified slurry cov ntaub ntawv, emulsified ayals, dej, fillers, thiab lwm yam. Raws li cov tuab tuab (3-10mm) yog tusyees kis rau ntawm txoj kev saum npoo los ua ib txheej asphalt saum toj kho. Tom qab demulsification, thawj qhov chaw, thiab solidification, cov tsos thiab muaj nuj nqi yog zoo ib yam li txheej txheem sab saum toj ntawm asphalt qhob. Nws muaj qhov zoo ntawm kev tsim kho yooj yim thiab kev tsim kho sai, kev siv tsheb qis, thiab kev tsim kho choj ntawm choj tau muaj qhov hnyav tsawg.
Cov haujlwm ntawm slurry sealing txheej yog:
l. Waterproof: Cov Slurry Sib xyaw ua kom khov kho rau txoj kev saum npoo av los ua ib txheej ntuj txheej txheej, uas tiv thaiv los nag thiab daus los ntawm cov txheej txheej.
2. Anti-Skid tuab yog nyias, thiab cov coarse aggregate yog tusyees faib rau ntawm cov npoo zoo, uas txhim kho cov kev ua tau zoo.
3. Hnav tsis kam: Hloov kho slurry Foob / micro-surfacing kev tsim kho kom txhim kho cov nplaum ntawm kev ua haujlwm ntawm txoj kev ua haujlwm. Cov.
4. Filling: Tom qab sib xyaw, cov sib tov yuav nyob rau hauv lub xeev slurry nrog zoo flue, uas ua rau qee lub luag haujlwm hauv kev sau cov kab nrib pleb thiab theem saum npoo av.
