Daim Ntawv Qhia Tag Nrho ntawm Kev Siv Bitumen 115/15
Bitumen 115/15 siv li cas
Nws yog qhov kev xaiv nrov rau ntau lub hom phiaj vim tias nws tuaj yeem siv ntau txoj hauv kev:
Bitumen ua haujlwm li cas (115/15) :Cov khoom uas ua rau bitumen 115/15
Kev nkag mus ntawm asphalt 115 15 yog muab los ntawm tus lej "15," uas sawv cev rau qhov ntsuas nkag thiab "115" rau qhov tsis muaj zog. Raws li cov lus piav qhia no, cov bitumen zoo li muaj qhov muag zoo nkauj, uas tuaj yeem siv tau rau qee lub sijhawm uas xav tau kev txav mus los. Vim nws yog thermoplastic, nws softens thaum rhuab thiab hardens thaum txias. Qhov no ua rau nws zoo meej rau qhov chaw uas qhov kub thiab txias hloov ntau zaus.
Kev tsim kho txoj kev:
Siv raws li ib tug binder nyob rau hauv asphalt sib tov ua kom lawv nyob ntev dua thiab tsis tshua muaj kev hnav los ntawm kev khiav tsheb.
Sealing: Vim tias nws tsis tso dej los, nws yog qhov zoo rau kev sib khi lub ru tsev, hauv qab daus, thiab hauv paus.
Cov txheej txheem tiv thaiv yog siv rau cov chaw hlau kom tsis txhob xeb, nrog rau cov vaj tse pob zeb ua kom lawv tiv taus cov tshuaj.
Npaj thiab tuav : Cov lus qhia txog kev khaws cov khoom
Txhawm rau tswj nws qhov zoo, bitumen 115/15 yuav tsum muab khaws cia kom raug. Txhawm rau kom tsis txhob qias neeg lossis tawg, nws yuav tsum tau khaws cia rau hauv qhov chaw qhuav, npog. Nws yog ib qho tseem ceeb uas yuav tsum tau saib xyuas qhov kub thiab txias; Qhov kub cia yuav tsum nyob qis dua 60 ° C kom cov asphalt tsis oxidize thiab tawg.
Ntxiv cua sov thiab sib tov
Nws yuav tsum tau muab cua sov sib npaug rau qhov kub ntawm 150 ° C txog 180 ° C ua ntej nws tuaj yeem siv tau. Nws yog ib qho yooj yim mus ua hauj lwm nrog thiab sib tov nrog aggregates los yog lwm yam tom qab cov txheej txheem no. Nws yog ib qho tseem ceeb heev kom tsis txhob kub ntau dhau, vim tias qhov no tuaj yeem ua rau thermal tawg lossis ua rau asphalt tsis nplaum.
Cov txheej txheem ntawm kev thov: Tsim ib txoj kev
Bitumen 115/15 feem ntau yog siv hauv kub sib xyaw asphalt (HMA) rau kev tsim kho. Nov yog cov kauj ruam koj yuav tsum tau ua kom siv cov av nkos no rau paving:
Npaj Npaj:
Txhawm rau kom paub tseeb tias cov txheej txheem asphalt tshiab tau zoo, txoj kev qub yuav tsum tau ntxuav thiab tsis muaj pov tseg. Bitumen thiab pebbles yog sib tov ntawm kub heev. Yuav kom tau txais txoj cai asphalt sib xws thiab ua haujlwm ntev, tus nqi ntawm cov bitumen nyob rau hauv lub aggregate yuav tsum tau ua tib zoo tswj.
Pw thiab Compacting: Cov kub asphalt sib tov yog nthuav tawm ntawm qhov chaw npaj, thiab cov chais siv los nias nws kom nws du thiab tuab.
Daim ntawv thov rau waterproofing
Nws tuaj yeem siv rau kev ua dej tsis zoo hauv cov ntawv kub lossis txias, raws li qhov xav tau: Thaum asphalt tau rhaub rau cov kua, nws yog siv nrog txhuam los yog tshuaj tsuag. Txoj kev no ua kom cov kua nplaum nplaum zoo thiab mus tob. Bitumen emulsions lossis kev daws teeb meem tuaj yeem siv rau ntawm qhov chaw uas tsis nyiam cua sov hauv huab cua txias. Cov no yooj yim dua los ua haujlwm nrog, tab sis lawv yuav xav tau sijhawm ntxiv los kho.
Txheej uas tiv thaiv
Yog tias koj xav tiv thaiv cov vaj tse hlau lossis pob zeb, bitumen 115/15 yog qhov kev xaiv zoo heev. Nws ua haujlwm zoo tshwj xeeb tshaj yog nyob rau hauv kev lag luam chaw uas muaj tshuaj tiv thaiv thiab kev tiv thaiv dej yog qhov tseem ceeb.
Ntxuav nto:
Cov npoo yuav tsum tsis muaj xeb, av, thiab cov xim qub ua ntej lawv tuaj yeem pleev xim. Ib txoj hauv kev ua qhov no yog siv kev sib tsoo lossis tshuaj ntxuav yog ib txoj hauv kev kom ua tiav qhov no.
Txhawm rau siv, asphalt tuaj yeem txau, txhuam, lossis dov rau hauv av. Nws yuav siv ntau tshaj ib txheej kom tau lub thickness thiab tus nqi ntawm kev tiv thaiv koj xav tau.
Nco ntsoov koj txoj kev nyab xeeb.
Cov Khoom Siv Tiv Thaiv Tus Kheej (PPE): Cov pa taws thiab kub kub uas los ntawm kev ua haujlwm nrog Bitumen 115/15 tuaj yeem tsim teeb meem. Nws yog ib qho tseem ceeb uas yuav tsum hnav PPE zoo, xws li tsom iav, hnab looj tes, thiab khaub ncaws uas tuaj yeem tiv taus cua sov. Nyob rau hauv cov chaw uas tsis muaj cua txaus, tej zaum koj yuav tau hnav tiv thaiv ua pa.
Txais thiab tuav cov khoom
Txhawm rau kom tsis txhob muaj xwm txheej, nws yog ib qho tseem ceeb uas yuav tsum tau ua thiab txav kub bitumen kom raug. Xyuas kom tseeb tias tag nrho cov cuab yeej koj siv tuaj yeem tswj tau qhov kub thiab txias, thiab cov thawv uas koj siv rau kev nqa yog insulated thiab kaw kom tsis txhob txeej.
Kev xav ntawm ib puag ncig
Bitumen yog cov khoom siv roj av, thiab ob qho tib si ua thiab siv nws muaj txiaj ntsig rau lub ntiaj teb. Yuav tsum muaj cov kauj ruam los txo cov pa phem thiab xyuas kom cov thoob khib nyiab pov tseg kom zoo. Bitumen yuav tsum tau rov ua dua kom tsawg dua cov khoom siv tshiab thiab kev puas tsuaj tsawg dua rau lub ntiaj teb. Qhov no muaj tseeb tshwj xeeb thaum tsim kev.
Recycling thiab Ua Ntsuab
RAP, los yog rov siv dua asphalt pavement, yog ib qho kev xaiv hauv eco-phooj ywg uas rov siv cov bitumen thiab aggregates los ntawm cov kev taug kev qub. Qhov no tsis tsuas yog txuag cov peev txheej ntuj xwb tab sis kuj txo qis cov pa hluav taws xob hauv tsev cog khoom uas los ntawm kev ua cov khoom siv asphalt tshiab.
Kev tu thiab lub neej ntev
Txhawm rau ua kom cov tsev cib siv tau ntev dua, lawv yuav tsum tau khaws cia tsis tu ncua. Qhov no suav nrog kev txhim kho cov kab nrib pleb hauv txoj kev, npog qhov chaw, thiab txhaws hauv cov poholes. Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau, nws yuav tsum tau kuaj xyuas cov dej tsis tu ncua.
Kho thiab kho
Thaum kev puas tsuaj tshwm sim, nws yog ib qho tseem ceeb uas yuav tsum tau kho tam sim ntawd kom tsis txhob muaj qhov tsis zoo. Qhov no tuaj yeem txhais tau tias kho lossis rov kho txoj kev. Rau cov tsev, qhov no tuaj yeem txhais tau tias ntxiv cov txheej txheem dej tsis zoo los yog ua rau kev tsim kho kom muaj zog.
Kev xav ntawm Tus Nqi
Nyob rau hauv lub sij hawm ntev, Bitumen 115/15 yog tus nqi-zoo vim nws siv sij hawm ntev thiab tsis xav tau kev tu ntau, tab sis nws tuaj yeem kim rau nruab thaum xub thawj. Qhov no suav nrog tus nqi ntawm cov cuab yeej, kev ua haujlwm, thiab cov khoom siv raw. Tab sis tus nqi feem ntau tsim nyog vim tias cov khoom siv tau ntev thiab ua haujlwm zoo.
Kev txheeb xyuas qhov sib txawv
Bitumen yog cov khoom siv zoo vim nws yog qhov sib xyaw zoo ntawm tus nqi thiab kev ua haujlwm zoo. Thaum siv los pav txoj kev, piv txwv li, nws ua rau saum npoo smoother thiab kav ntev dua lwm cov ntaub ntawv paving. Qhov no txo ​​qis tus nqi kho mob thiab ua rau txoj kev nyab xeeb dua.
Txhim kho nyob rau hauv thev naus laus zis
Kev tsim kho tshiab hauv kev siv tshuab bitumen suav nrog kev tsim cov hloov kho bitumen uas muaj cov polymers kom nws hloov tau yooj yim thiab siv tau ntev. Nrog rau cov kev hloov no, lub tarmac tuaj yeem ua haujlwm zoo dua nyob rau hauv huab cua hnyav thiab muaj tsheb ntau.
Yuav Ua Li Cas?
Cov kauj ruam tom ntej rau kev siv tshuab bitumen yog ua kom tsis muaj teeb meem rau lub ntiaj teb. Ob lub tswv yim tshiab zoo siab uas tuaj yeem ua rau cov roj av ntau dua ib puag ncig yog kev tsim cov bio-bitumen los ntawm cov peev txheej ntuj thiab kev siv cov khoom siv rov ua dua tshiab.
Nyob rau hauv xaus
Niaj hnub no, bitumen 115/15 yog ib yam khoom tseem ceeb rau lub tsev thiab kev lag luam vim nws muaj ntau yam thiab siv tau ntev. Los ntawm kev nkag siab txog nws cov khoom thiab kev siv kom raug, peb tuaj yeem ua kom nws cov txiaj ntsig zoo nrog qhov cuam tshuam tsawg. Bitumen yuav yog ib feem tseem ceeb ntawm kev tsim cov infrastructure ntawm lub neej yav tom ntej tsuav yog peb pheej los nrog cov tswv yim tshiab thiab ua kom cov cuab yeej siv bitumen zoo dua.
Txhawm rau nce cov thev naus laus zis tshiab thiab cov qauv tshiab yog qhov tseem ceeb rau cov neeg uas xav kawm ntxiv txog asphalt lossis siv nws hauv lawv cov haujlwm. Txais kev coj tus cwj pwm zoo ib puag ncig thiab nrhiav txoj hauv kev tshiab los siv bitumen zoo dua thiab ua tau zoo.
