Raws li peb txhua tus paub, micro-surfacing thiab slurry sealing yog ob tus neeg sib txawv ntawm kev siv, yog li cov neeg siv kev tiv thaiv kev tiv thaiv zoo ib yam li koj qhia koj qhov sib txawv ntawm ob.

1. Muaj feem rau txoj kev sib txawv hauv txoj kev: micro-surfacing yog siv rau kev tiv thaiv kev saib xyuas ntawm kev loj thiab sau ntawm lub teeb ruts. Nws tseem haum rau kev tawm tsam plam txoj hmoov ntawm cov khaubncaws txoj kev loj tshiab. Lub Slurry Foob yog siv rau kev saib xyuas kev ntawm txoj kev theem nrab thiab hauv qab no, thiab tseem siv tau rau hauv qab ntawm txoj kev tshiab.
2. Qhov zoo ntawm aggregates yog qhov sib txawv: lub cev tsis muaj zog ntawm kev siv rau micro-surfacing yuav tsum muaj ntau tshaj 35% rau kev sib sau ua ke rau cov slurry sealing; Cov aggregates siv rau micro-surfacing hla dhau ntawm 4.75mm sab cib ntawm cov khoom siv hluavtaws yuav tsum tau siab dua li 45% uas yuav tsum tau siv rau kev sib khi slurry.
3. Cov kev xav tau sib txawv Siv emulsified asphalt ntau dua qhov yuav tsum tau ntawm 60%.
4. Cov qauv tsim txhais tau ntawm ob cov sib tov sib txawv yuav tsum ua kom tau raws li cov log ntub dej tom qab tau xau dej rau 6 hnub, thiab cov slurry foob tsis tas yuav tsum; Lub micro-sib tov tuaj yeem siv rau rut filling, thiab cov sib tov muaj lub log tsheb tau qis dua li 5%, thaum lub slurry foob txheej txheej tsis tau.
Nws tuaj yeem pom tau tias txawm hais tias micro-surfacing thiab slurry sealing zoo ib yam li nyob rau qee qhov chaw, lawv yeej txawv heev. Thaum siv lawv, koj yuav tsum xaiv raws li qhov xwm txheej tiag tiag.
