Thaum peb taug kev ntawm txoj kev loj thiab txoj kev loj ntawm lub nroog, peb yuav tsis xav txog seb hom kev tshawb fawb thiab kev hnav khaub ncaws nyob tom qab hauv peb ko taw. High-viscosity asphalt, uas yog lub npe hu ua "dub technology" hauv kev ua haujlwm ntawm txoj kev engineering, yog maj mam ua qhov kev nyiam tshiab hauv kuv lub teb chaws txoj kev siv. Kab lus no yuav coj koj mus kawm txog kev siv thev naus laus zis ntawm kev siv hom kab mob txhab siab thiab qhia tawm cov khoom siv nrov.

1. Lub ntsiab lus ntawm high-viscosity asphalt
High-viscosity Asphalt, raws li lub npe qhia, yog hom npe hais, yog ib hom asphalt nrog cov viscant siab, uas feem ntau yog siv hauv asphalt sib tov hauv txoj kev siv. Cov khoom lag luam asphalt muaj lub viscosity siab thiab tuaj yeem ua ke zoo dua nrog lwm cov kev sib txuas ntawm txoj kev sab nraud, yog li kev txhim kho qhov ruaj khov, kav ntev thiab deformation tsis kam ntawm txoj kev. Nyob rau tib lub sijhawm, siab-viscosity Asphalt kuj tseem tuaj yeem txhim kho los ntawm kev ntxiv cov qauv hloov kho, xws li nce cov moulding lub zog thiab deformation rov qab muaj peev xwm ntawm kev sib xyaw.
2. Qhov zoo ntawm high-viscosity asphalt
1. Cov hnav zoo heev: raws li kev txiav txim ntawm tsheb thauj khoom, siab-viscosity evaphalt tuaj yeem sau cov khoob ntawm txoj kev saum npoo av, thiab txhim kho kev coj ua ntawm txoj kev nto. Qhov kev coj ua zoo tshaj plaws ua rau cov viscosity asphalt muaj qhov tseem ceeb nyob rau hauv daim ntawv thov hnyav-thauj cov kev pabcuam lub neej thiab txo tus nqi kho.
2. Cov tawg ua haujlwm tsis kam: Thaum lub sijhawm kev tsim kho, qib siab-viscosity yuav txo txoj kev tawg kom tsawg, yog li txuas ntxiv txoj kev pabcuam ntawm txoj kev.
3. Kev ua kom pom zoo los tiv thaiv kev ua haujlwm: High-viscosity asphalt muaj cov tshuaj ntxiv uas muaj cov antioxidants, uas tuaj yeem tiv thaiv kev ruaj khov ntawm asphalt thiab muaj kev ruaj ntseg ntawm cov qauv asphalt molecular. Nyob rau hauv cov cawv ntawm tej yam ntuj xws li tshav ntuj thiab kub, siab-viscosity asphalt tuaj yeem ua kom zoo ua tau zoo thiab ua kom cov kev nplij siab ntawm txoj kev siv. Kuj tsis pom zoo kev ua haujlwm tseem muaj kev pab kom txo tau cov zaus thiab them nqi ntawm kev txij nkawm thiab nce kev pabcuam lub neej ntawm txoj kev.
4. Ib puag ncig tus phooj ywg: Hauv cov txheej txheem ntau lawm ntawm cov log tsheb zoo li cov tub log tsheb kom paub cov khoom pov tseg thiab txo cov pa phem rau ib puag ncig. Thaum lub sijhawm siv cov high-viscosity asphalt, qhov kev cuam tshuam rau ib puag ncig yog qhov me me, uas yog qhov ua kom zoo rau kev ua tiav lub hom phiaj ntawm kev tsim kho ntsuab thiab muaj kev txhim kho kom ruaj khov.
3. High-Viscosity Asphalt Siv Txheej Txheem Qhia Tawm
1. Siv kev tsim khoom
Ua ntej pib kev tsim kho ntawm high-viscosity asphalt sib xyaw, cov kev npaj npaj yuav tsum tau nqa tawm. Thawj kauj ruam yog xaiv cov khoom zoo siab high-viscosity high-viscosity high-viscosity thiab additives thiab lwm cov ntaub ntawv raw raws li cov qauv yuav tsum tau ua. Qhov zoo ntawm cov khoom raw ncaj qha cuam tshuam rau kev ua tau zoo thiab kev pabcuam lub neej ntawm kev sib xyaw. Nws tseem tsim nyog los tshawb xyuas thiab xyuas kom meej tias cov khoom siv tsim kho tiav, suav nrog cov haujlwm ua haujlwm ntawm cov chaw xws li kev sib xyaw, thiab cov zaub mov. Txoj kev ua tau zoo thiab kev ua haujlwm ntawm cov khoom siv no yuav tsum tau ua kom tau raws li cov kev tsim kho tsim kho kom ua tau zoo thiab ua haujlwm zoo ntawm kev tsim kho. Thaum lub sijhawm tsim kho yuav tsum tau kaw thiab tswj hwm kom ntseeg tau tias muaj kev nyab xeeb thiab tiv thaiv kev nyab xeeb thiab ib puag ncig kev muaj kuab paug thaum lub sij hawm tsim kho.
2. Sib tov npaj
Tso cov viscosity high-viscosity, cov ntaub ntawv me thiab ntxiv rau hauv cov tov khoom hauv ib qho kev faib ua feem thiab sib xyaw. Thaum lub sij hawm sib xyaw, lub sijhawm sib xyaw thiab nrawm dua yuav tsum tau tswj hwm kom ntseeg tau tias qhov kev sib xyaw thiab kev ruaj ntseg ntawm cov sib tov. Tom qab tov tiav, cov sib tov yuav tsum tau kuaj xyuas kom ntseeg tau tias nws ua tau zoo raws li cov qauv cai yuav tsum tau ua.
3. Paving kev ua haujlwm
Ncuav cov mixed high-viscosity Asphalt sib xyaw rau hauv cov paver, thiab siv cov paver, thiab siv cov paver rau tusyees sib xyaw ntawm txoj kev sib xyaw. Thaum lub sij hawm paving txheej txheem, paving tuab thiab nrawm yuav tsum tau tswj hwm kom ntseeg tau tias qhov sib xyaw ua ke. Nyob rau tib lub sijhawm, cov txheej txheem paving yuav tsum tau raug saib xyuas kom pom thiab cuam tshuam nrog cov teeb meem raws sijhawm.
4. Dov kev ua haujlwm
Tom qab paving tiav, dov yog nqa tawm tam sim ntawd. Ua ntej, tus hlau log cov menyuam yog siv rau kev pib yob kom tshem tawm cov voids thiab tsis sib xws hauv cov dej sib tov. Tom qab ntawd lub log tsheb yog siv rau kev rov rolling los txhim kho lub ntom ntom thiab ruaj khov ntawm cov sib tov. Thaum kawg, tus menyuam vibrating yog siv rau kev siv zaum kawg los txhim kho qhov ceev thiab tiaj tus sib xyaw. Thaum lub sij hawm rolling txheej txheem, tus yob nrawm thiab tus naj npawb ntawm cov passes yuav tsum tau tswj hwm kom ntseeg tau tias kev sib xyaw.
5. Qhib tsheb
Tom qab dov tau ua tiav, nws yog ib qho tsim nyog los tos kom lub siab-viscosity asphalt sib xyaw kom txias ua ntej qhib tsheb. Thaum lub sij hawm txias txheej txheem, txoj kev sab saum toj yuav tsum tau saib xyuas kom tiv thaiv cov kab nrib pleb thiab deformation tshwm sim los ntawm qhov kub hloov. Nyob rau tib lub sijhawm, txoj kev sab saum toj uas yuav tsum tau khaws cia tsis tu ncua thiab kuaj xyuas kom ntseeg tau tias nws qhov kev ua tau zoo thiab kev pabcuam lub neej.
Daim ntawv thov ntawm high-viscosity Asphalt asphalt siv tshuab muab kev tsim kho tshiab rau kuv lub teb chaws txoj kev tsim khoom lag luam. Lub tshuab kev lag luam tshiab no yog qhov tseem ceeb hauv kev txhim kho txoj kev ua tau zoo, kev pab tsev ntawm lub neej, thiab txo tus nqi kho. Nyob rau hauv lub neej yav tom ntej, nrog kev txhim kho txuas ntxiv thiab txhim kho ntawm cov siab-viscosity thev naus laus zis mus rau hauv kuv lub teb chaws txoj kev lag luam thiab ua kom peb mus ncig ua si yooj yim dua thiab xis.
