Case Study: Pov Tseg Asphalt Regenerant Application in Urban Road Renovation
Kev tsim kho kev ntsuab thiab kev siv cov khoom siv rov ua dua tshiab tau nce siab hauv kev tsim kho kev lag luam, thiab kev siv cov khib nyiab asphalt pavement tau maj mam dhau los ua qhov txuas tseem ceeb ntawm kev kho vaj tse thiab kho dua tshiab. Nyob rau hauv txoj kev kho dua tshiab ntawm txoj kev hauv nroog hauv nroog, muaj cov teeb meem tseem ceeb xws li kev laus loj, tawv thiab tawg ntawm txoj kev qub, thiab kev ua haujlwm tsis zoo ntawm kev rov ua dua asphalt pavement (RAP). Peb lub tuam txhab launched ib lub hom phiajpov tseg asphalt regenerantdaim ntawv thov tswv yim rau txoj haujlwm no, thiab ua tiav qhov ua tau zoo thiab siab - rov ua dua cov ntaub ntawv pov tseg asphalt zoo.
Txoj kev tsheb ciav hlau hauv nroog tau muab tso rau hauv ntau tshaj 8 xyoo. Ntev - lub sij hawm hnyav tsheb thauj mus los, hnub ci hluav taws xob, nag yaig thiab oxidative kev laus ua rau poob loj ntawm cov khoom viscous nyob rau hauv thawj asphalt binder, thiab cov pavement qhov yooj thiab stability poob sharply. Lub koom haum ua haujlwm tau muab cov kev xav tau meej meej: los ntawm kev ua kom muaj kev tsim kho kom zoo thiab kev pabcuam lub neej ntawm txoj kev, nce qhov feem ntawm RAP rov qab siv dua, txo qis kev noj cov asphalt tshiab thiab aggregates, thiab txo cov pa phem ib puag ncig los ntawm kev pov tseg pavement pov tseg.
Pebpov tseg asphalt regeneranttso siab rau nws tus kheej tsim siab -permeability active formula, uas tuaj yeem nkag mus rau sab hauv ntawm cov laus asphalt, ntxiv rau cov khoom uas tsis muaj ntxhiab tsw, kho cov qauv colloidal puas ntawm asphalt, thiab rov ua cov qub adhesion thiab plasticity ntawm cov laus asphalt. Thaum lub sij hawm tsim kho, pab neeg tsim ua ntej crushed thiab tshuaj xyuas cov khoom siv asphalt, tom qab ntawd ntxiv cov regenerant nyob rau hauv nruj raws li qhov optimized proportions, thiab tag nrho stirred nws nrog tshiab asphalt thiab graded aggregates los npaj recycled asphalt sib tov. Tag nrho kev sib xyaw thiab kev ua haujlwm paving yog du, lub regenerant tsis muaj ntxhiab tsw ntxhiab thiab tsis muaj teeb meem tsis haum tshuaj, uas ua tau raws li tag nrho ntawm -site kev tiv thaiv ib puag ncig cov qauv tsim.
Tom qab ua tiav ntawm qhov project, qhov thib peb - kev sim thib peb thiab tom qab qhov kev tshuaj ntsuam xyuas theem ob pom tau tias txoj kev ua tau zoo raws li lub teb chaws tus qauv specifications. Kev nkag mus, ductility thiab adhesion ntawm regenerated asphalt tau ua tiav rov qab mus rau qib ntawm asphalt tshiab, cov pavement nto yog tiaj thiab compact, thiab kev tiv thaiv kom tawg, rutting thiab tev tau zoo txhim kho. Qhov project no tsis tsuas yog txhim kho kev siv cov ntaub ntawv pov tseg asphalt, txuag nyiaj ntau ntawm cov khoom siv engineering, tab sis kuj txo cov ecological siab los ntawm cov stacking thiab pov tseg ntawm cov khib nyiab pavement, tsim dual txiaj ntsig ntawm kev lag luam thiab kev tiv thaiv ib puag ncig.
Cov ntaub ntawv thov siv tau no tau lees paub qhov ua tau zoo thiab kev ua tau zoo ntawm pebpov tseg asphalt regenerantnyob rau hauv asphalt pavement recycling tej yaam num. Peb lub tuam txhab tseem yuav tsom mus rau kev tshawb fawb thiab kev tsim kho thiab kev siv thev naus laus zis ntawm cov ntaub ntawv ntsuab asphalt, thiab muab cov khoom siv txhim khu kev qha, muaj txiaj ntsig zoo thiab ib puag ncig zoo rau kev daws teeb meem thoob ntiaj teb kev saib xyuas thiab kev tsim kho cov haujlwm.
