Raws li peb txhua tus paub, micro-surfacing thiab slurry foob yog ob qho tib si kev tiv thaiv kev siv thev naus laus zis, thiab cov txheej txheem phau ntawv zoo sib xws, yog li ntau tus neeg tsis paub yuav ua li cas paub qhov txawv ntawm kev siv tiag tiag. Yog li ntawd, tus editor ntawm Sinosun tuam txhab xav siv lub sijhawm no los qhia koj qhov txawv ntawm ob.
1. Cov kev siv sib txawv ntawm qhov chaw: Micro-surfacing feem ntau yog siv los tiv thaiv kev saib xyuas thiab sau lub teeb rutting ntawm txoj kev loj, thiab tseem tsim nyog rau cov khaubncaws sab nraud povtseg ntawm kev tsim kho tshiab. Slurry foob feem ntau yog siv los tiv thaiv kev saib xyuas ntawm txoj kev loj theem nrab thiab qis, thiab tseem tuaj yeem siv rau hauv cov txheej txheem qis ntawm txoj kev loj uas tau tsim tshiab.

2. Cov khoom sib txawv sib txawv: Kev hnav tsis zoo ntawm cov aggregates siv rau micro-surfacing yuav tsum tsawg dua 30%, uas yog nruj dua li qhov yuav tsum tau ua tsis pub tshaj 35% rau cov khoom sib xyaw siv rau slurry foob; cov xuab zeb sib npaug ntawm cov khoom siv hluavtaws sib xyaw siv rau micro-surfacing los ntawm 4.75mm sieve yuav tsum siab dua 65%, thiab ntau dua li qhov yuav tsum tau ua ntawm 45% rau slurry foob.
3. Cov kev cai sib txawv: Slurry foob siv unmodified emulsified asphalt ntawm ntau hom, thaum micro-surfacing siv hloov ceev ceev emulsified asphalt, thiab cov ntsiab lus seem yuav tsum siab tshaj 62%, uas yog siab tshaj qhov yuav tsum tau ntawm 60% rau emulsified. asphalt siv nyob rau hauv slurry foob.
4. Cov qauv tsim ntawm cov khoom sib xyaw ntawm ob qhov sib txawv: qhov sib xyaw ntawm micro-surfacing yuav tsum tau ua kom tau raws li lub log ntub dej index ntawm 6 hnub ntawm immersion hauv dej, thaum lub slurry foob tsis xav tau; micro-surfacing tuaj yeem siv rau rutting filling, thiab nws qhov sib tov yuav tsum muaj qhov kev hloov pauv sab nraud ntawm tus qauv tsawg dua 5% tom qab 1,000 zaug ntawm dov los ntawm lub log loaded, thaum lub slurry foob tsis.
Nws tuaj yeem pom tau tias txawm hais tias micro-surfacing thiab slurry foob zoo ib yam hauv qee qhov chaw, lawv yeej txawv heev. Thaum siv lawv, koj yuav tsum xaiv raws li qhov xwm txheej tiag tiag.
