Ua ntej, lub ntsiab lus ntawm kev tiv thaiv kev saib xyuas ntawm asphalt qhob pavement qauv yog qhia, thiab tam sim no kev tshawb fawb, kev loj hlob thiab daim ntawv thov txheej xwm ntawm kev tiv thaiv txij nkawm ntawm asphalt qhob pavement qauv nyob rau hauv tsev thiab txawv teb chaws tau sau tseg. Cov kev tsim kho uas nquag siv ntawm kev tiv thaiv kev saib xyuas ntawm asphalt qhob pavement qauv tau qhia, thiab tom qab kev kho mob thiab lwm yam teeb meem tseem ceeb ntawm kev tiv thaiv kev saib xyuas ntawm asphalt qhob pavement qauv raug tshuaj xyuas thiab sau, thiab kev txhim kho yav tom ntej yog prospected.

Tiv thaiv kev txij nkawm
Kev tiv thaiv kev saib xyuas yog hais txog ib txoj hauv kev txij nkawm uas tau ua thaum cov txheej txheem pavement tseem tsis tau puas lawm. Nws txhim kho kev khiav hauj lwm ntawm cov txheej txheem pavement thiab ncua kev puas tsuaj ntawm asphalt pavement yam tsis tau nce lub peev xwm ntawm cov qauv. Piv nrog rau cov txheej txheem kev saib xyuas ib txwm muaj, kev tiv thaiv kev saib xyuas yog qhov muaj txiaj ntsig ntau dua thiab xav tau kev npaj tsim nyog kom ua tiav cov txiaj ntsig xav tau.
Txij li xyoo 2006, yav dhau los Ministry of Transport tau txhawb nqa kev siv kev tiv thaiv kev tiv thaiv thoob tebchaws. Xyoo kaum xyoo dhau los, kuv lub teb chaws txoj kev loj engineering cov neeg ua haujlwm tau pib txais thiab siv kev tiv thaiv kev saib xyuas, thiab kev siv thev naus laus zis ntawm kev tiv thaiv kev saib xyuas tau dhau los ua neeg paub tab. Thaum lub sij hawm "Twelfth Five-Year Plan", qhov kev faib ua feem ntawm kev tiv thaiv kev saib xyuas hauv kuv lub teb chaws txoj haujlwm kho tau nce los ntawm tsib feem pua ​​​​ntawm cov ntsiab lus txhua xyoo, thiab ua tiav txoj kev ua tau zoo kawg nkaus. Txawm li cas los xij, nyob rau theem no, kev tiv thaiv kev tiv thaiv kev ua haujlwm tseem tsis tau paub tab, thiab tseem muaj ntau qhov chaw yuav tsum tau kawm. Tsuas yog los ntawm ntau qhov sib txuam thiab kev tshawb fawb tuaj yeem tiv thaiv kev siv tshuab ua kom paub tab thiab ua tiav kev siv tau zoo dua.
Cov txheej txheem tseem ceeb ntawm kev tiv thaiv kev saib xyuas
Nyob rau hauv kuv lub teb chaws txoj kev loj engineering kev saib xyuas, raws li qhov ntsuas thiab qhov nyuaj ntawm txoj haujlwm txij nkawm, qhov kev saib xyuas tau muab faib ua: kev saib xyuas, kho me me, kho nruab nrab, kho loj thiab kho dua tshiab, tab sis tsis muaj kev sib cais ntawm kev tiv thaiv kev saib xyuas, uas yuav cuam ​​tshuam zoo heev rau kev siv cov kev tiv thaiv kev tiv thaiv. Yog li ntawd, nyob rau hauv kev txhim kho kev txij nkawm yav tom ntej, kev tiv thaiv kev tiv thaiv yuav tsum tau suav nrog hauv kev saib xyuas. Tam sim no, txoj kev tsim kho feem ntau siv nyob rau hauv tsev thiab txawv teb chaws rau kev tiv thaiv kev txij nkawm ntawm asphalt qhob pavement qauv xws li sealing, slurry sealing micro-surfacing, pos huab sealing thiab crushed pob zeb sealing.
Sealing feem ntau muaj ob hom: grouting thiab grouting. Grouting yog siv cov kua nplaum engineering rau kev sib khi ncaj qha ntawm qhov chaw uas muaj kab nrib pleb tshwm sim ntawm txoj kev. Txij li cov kab nrib pleb raug kaw nrog cov kua nplaum, qhov loj ntawm cov kab nrib pleb tsis tuaj yeem loj dhau. Txoj kev no tsuas yog tsim nyog rau cov kab mob uas muaj kab mob me me thiab me me tawg dav. Thaum kho, gel nrog viscoelasticity zoo thiab kub ruaj khov yuav tsum tau siv los kho cov kab nrib pleb, thiab cov kab nrib pleb uas tshwm sim yuav tsum tau kho raws sijhawm. Sealing yog hais txog cua sov qhov puas ntawm txoj kev nto thiab txiav nws qhib, thiab tom qab ntawd siv sealant los kaw cov seams hauv cov grooves.
Slurry sealing micro-surface technology yog hais txog txoj kev nthuav tawm cov khoom sib xyaw uas tsim los ntawm kev sib xyaw ntawm cov pob zeb, emulsified asphalt, dej, thiab muab tub lim rau ntawm txoj kev siv lub slurry sealer. Txoj kev no tuaj yeem txhim kho txoj kev ua tau zoo ntawm txoj kev nto, tab sis nws tsis haum rau kev kho mob ntawm txoj kev kab mob nrog cov kab mob loj.
Mist sealing thev naus laus zis siv lub tshuab asphalt txhawm rau txhawm rau txhawm rau txhawm rau hloov kho asphalt ntawm txoj kev nto los tsim cov txheej txheem dej tsis zoo. Cov txheej txheem tshiab tsim cov dej tsis zoo tuaj yeem txhim kho cov dej tsis kam ntawm txoj kev nto thiab tiv thaiv kom tsis txhob ya raws los ntawm kev puas tsuaj rau sab hauv.
Chip foob tshuab siv lub tshuab txau tsis siv neeg los siv tus nqi tsim nyog ntawm asphalt ntawm txoj kev, ces kis pob zeb ntawm qee qhov me me ntawm asphalt, thiab thaum kawg siv lub log tsheb rau yob rau hauv cov duab. Txoj kev nto kho nrog nti foob tshuab tau zoo heev nws txoj kev tiv thaiv kev ua haujlwm thiab dej tsis kam.
