Raws li peb txhua tus paub, micro-surfacing thiab slurry sealing yog ob qho tib si kev tiv thaiv kev tiv thaiv ib puag ncig, thiab cov txheej txheem phau ntawv kuj zoo sib xws, yog li ntau tus neeg tsis paub yuav ua li cas kom paub qhov txawv ntawm qhov siv tiag tiag, yog li tus editor ntawm Sinoroader xav tau. siv lub sijhawm no Cia kuv qhia koj qhov txawv ntawm ob.

1. Muaj feem xyuam rau txoj kev sib txawv: Micro-surfacing feem ntau yog siv los tiv thaiv kev loj thiab txhaws ntawm lub teeb ruts. Nws kuj tseem tsim nyog rau cov khaubncaws sab nraud povtseg ntawm kev tsim kho tshiab. Lub slurry foob feem ntau yog siv rau kev tiv thaiv kev saib xyuas ntawm txoj kev thib ob thiab hauv qab no, thiab tseem tuaj yeem siv rau hauv qis dua ntawm txoj kev tshiab.
2. Qhov zoo ntawm aggregates yog txawv: kev puas tsuaj ntawm cov aggregates siv rau micro-surfacing yuav tsum tsawg dua 30%, uas yog nruj dua li qhov yuav tsum tau tsis pub tshaj 35% rau aggregates siv slurry sealing; cov aggregates siv rau micro-surfacing dhau los ntawm 4.75mm sieve Cov xuab zeb sib npaug ntawm cov khoom siv hluavtaws yuav tsum siab dua 65%, uas yog qhov siab dua li 45% kev xav tau thaum siv slurry sealing.
3. Cov kev cai sib txawv: slurry foob siv ntau hom unmodified emulsified asphalt, thaum lub micro nto siv hloov ceev ceev emulsified asphalt, thiab cov ntsiab lus seem yog siab dua 62%, uas yog siab dua li ntawm slurry foob. Siv emulsified asphalt siab tshaj qhov yuav tsum tau ntawm 60%.
4. Cov qauv tsim ntawm ob qhov sib tov sib txawv: qhov sib xyaw ntawm micro-surface yuav tsum tau ua kom tau raws li lub log ntub dej tom qab tau ntub dej rau 6 hnub, thiab cov slurry foob tsis tas yuav tsum tau; micro-surface mix yuav siv tau rau rut filling, thiab cov sib tov muaj ib tug load log rolling yuav tsum tau ntawm 1000 Lub lateral txav ntawm tus qauv tom qab kev ntsuam xyuas yog qis dua qhov yuav tsum tau 5%, thaum lub slurry foob txheej tsis.
Nws tuaj yeem pom tau tias txawm hais tias micro-surfacing thiab slurry sealing zoo sib xws hauv qee qhov chaw, lawv yeej txawv heev. Thaum siv lawv, koj yuav tsum xaiv raws li qhov xwm txheej tiag tiag.
