Kev kho txoj kev thiab kho cov khoom lag luam asphalt thaj yog cov khoom siv yooj yim thiab yooj yim thiab yooj yim thiab yooj yim thiab yooj yim thiab yooj yim thiab yooj yim thiab yooj yim thiab yooj yim thiab yooj yim Cov hauv qab no yog cov lus qhia ntxaws ntxaws:
1. Cov lus txhais thiab muaj pes tsawg leeg
Asphalt txias thaj khoom, tseem ua kom txias dua cov khoom siv los ntawm kev sib xyaw ua ke, yog cov tshuaj sib cais, cov khoom ntxiv tshwj xeeb thiab cov pob zeb). Cov ntaub ntawv no tau sib xyaw raws li qee qhov kev faib ua feem ntawm kev ua kom asphalt ua "asphalt txias repllingishing kua", thiab tom qab ntawd sib xyaw nrog cov khoom siv thaum kawg ua cov ntaub ntawv tiav.
2. NTA THIAB ZOO
Hloov kho, tsis tag ua kom tiav cov khoom siv hluav taws xob: asphalt ntim cov khoom siv yog hloov kho kev sib xyaw zoo nkauj, uas muaj qhov zoo ntawm kev txhaj tshuaj ncaj qha.
Cov khoom siv hluav taws xob zoo: ntawm qhov kub thiab txias, asphalt thaj khoom siv yog kua thiab tuab, nrog cov khoom ruaj khov. Nws yog cov khoom tseem ceeb raw rau txias thaj ntau lawm.
Ntau yam ntawm daim ntawv thov: nws tuaj yeem siv nruab nrab ntawm -30 ℃ thiab 50 ℃, thiab tuaj yeem siv tag nrho cov huab cua. Nws yog qhov haum rau kev kho ntau hom kev nyob rau hauv ib qho huab cua thiab ib puag ncig, Maas pob zeb ntau, chaw nres tsheb, tshav dav hlau khiav, thiab choj. Cov xwm txheej xws li cov pob qij txha nthuav dav, pothoctive ntawm kev loj, kev loj thiab hauv zej zog kev loj, kev sib koom tes hauv zej zog thiab sau cov raj xa khoom, thiab lwm yam.
Tsis muaj cov cua sov yuav tsum muaj: piv nrog kub sib tov, asphalt thaj tov, asphalt thaj chaw tuaj yeem siv tsis tau muaj cua sov, txo cov hluav taws xob noj thiab cov pa hluav taws xob.
Yooj yim rau kev khiav lag luam: Thaum siv, tsuas yog hliv cov khoom txias rau hauv lub pits thiab compact nws nrog lub cuab yeej duav lossis cov cuab yeej ua ke.
Kev ua tau zoo heev: asphalt thaj ua khoom muaj cov khoom muaj siab thiab cohesion, tuaj yeem tsim cov qauv txheej txheem tag nrho, thiab tsis yooj yim rau tev thiab txav.
Yooj yim cia: Tsis tas yuav muab cov khoom siv rau cov khoom siv asphalt tuaj yeem muab khaws cia rau kev siv tom ntej.

3. Cov kauj ruam tsim khoom
Cov lauj kaub ntxuav: txiav txim siab qhov chaw nyob ntawm qhov chaw khawb, thiab zeb lossis txiav cov chaw ib puag ncig. Ntxuav cov gravel thiab pov tseg cov khib nyiab nyob rau hauv thiab ib ncig ntawm lub qhov taub yuav tsum tau kho kom txog thaum muaj cov khoom tawg thiab tawv. Nyob rau tib lub sijhawm, yuav tsum tsis muaj av nkos, dej khov lossis lwm cov khib nyiab hauv qhov taub. Thaum grooving, lub hauv paus ntsiab lus ntawm "kev kho xwmfab rau cov pits txuas ntxiv rau cov pits nruam
Kev txhuam hniav interface NTUG SEUMER / emulsified asphalt: txhuam cov neeg sawv cev ntawm Asly Cov nyiaj tau pom zoo yog 0.5 kg ib square meter kom haum ntawm qhov haum thiab txhim kho cov dej tsis zoo ntawm cov pob qij txha ua ke.
Sau lub qhov: Sau txaus asly asphalt thaj khoom cov khoom rau hauv lub qhov taub kom txog rau thaum tus muab tub lim yog li 1.5 cm saum toj hauv av. Thaum kho cov kev hauv nroog, cov lus tawm ntawm cov khoom siv txias tuaj yeem nce li 10% lossis 20%. Tom qab sau, qhov chaw nruab nrab ntawm lub qhov yuav tsum yog siab me ntsis ntau dua li cov npoo puag ncig thiab hauv cov duab arc. Yog hais tias qhov tob ntawm lub qhov saum npoo av loj dua 5 cm, nws yuav tsum tau sau nyob rau hauv txheej thiab compacted txheej los ntawm txheej, nrog 3 mus rau 5 cm ib txheej ua kom tsim nyog.
Kev sib koom tes: Tom qab paving tusyees, xaiv cov cuab yeej ua kom tsim nyog thiab cov hau kev tsim nyog cov cuab yeej ua kom haum raws li qhov loj me, qhov loj me thiab qhov chaw ntawm thaj chaw kho. Rau potholes nrog thaj chaw loj dua, cov menyuam tuaj yeem siv rau kev ua kom tau; Rau potholes nrog thaj chaw me me, lub tshuab tamping hlau tuaj yeem siv rau kev ua kom sib dhos. Tom qab cov kab ke, cov chaw kho yuav tsum muaj qhov chaw du, tiaj tiaj tsis muaj log log, thiab ib puag ncig thiab fab ntawm lub qhov yuav tsum tau sib cav thiab tsis xoob. Yog tias cov neeg mob tso cai, tus paver tuaj yeem siv rau kev ua haujlwm. Yog tias siv lub tshuab paving tsis muaj, ib lub forklift tuaj yeem siv los nqa lub hnab nqa, qhib hauv qab chaw nres nkoj tawm, thiab rov qab ua kev tsim kho. Thaum tso cov khoom siv, tus kheej txhuam nws tiaj tus thiab ua raws li thawj zaug dov. Tom qab dov, txias nws txog li 1 teev. Nyob rau lub sijhawm no, visually pom tias tsis muaj dej txias rau saum npoo lossis xyuam xim rau lub log Hub cim thaum dov. Yog tias tsis muaj kev txawv txav, cov menyuam me me tuaj yeem siv rau qhov kawg ntov. Qhov thib ob dov yuav nyob ntawm cov degree ntawm solidification. Yog tias nws tseem ntxov dhau lawm, yuav muaj log log. Yog tias nws yog lig dhau lawm, lub tiaj tiaj yuav cuam tshuam vim yog cov solidification ntawm txoj kev saum npoo. Manually tsuas yog txiav cov npoo thiab xyuam xim rau seb muaj lub log nplaum. Yog tias muaj lub log nplaum, cov menyuam yuav ntxiv cov dej xab npum kom ntub nws kom tshem tawm cov khoom daig rau lub log steel. Yog tias lub log tsis txaus siab yog qhov loj, txuas lub sijhawm txias kom tsim nyog. Tom qab tu thiab kab ke, ib txheej ntawm cov hmoov av lossis cov xuab zeb tau zoo tuaj yeem yog cov khoom siv tu kom zoo kom cov xuab zeb ntxuav tau tuaj yeem sau cov khoob. Qhov saum npoo ntawm kev kho lub qhov muag yuav tsum yog tus, tiaj, thiab dawb ntawm lub log log. Cov ces kaum ib ncig ntawm lub qhov yuav tsum tau sib xyaw thiab yuav tsum tsis muaj looseness. Kev ua kom raws kev txhim kho txoj hauv kev zoo tib yam yuav tsum ncav cuag ntau dua li 93%, thiab kev ua raws qib kev kho kom tau nce ntxiv dua 95%.
Qhib kev tsheb khiav: cov tsheb taug kev thiab cov tsheb tuaj yeem dhau tom qab thaj chaw kho tau zoo dua thiab ua tau raws li cov kev mob rau kev qhib tsheb. Cov neeg taug kev tuaj yeem hla dhau tom qab dov ob mus rau peb zaug thiab cia nws sawv ntsug rau 1 txog 2 teev, thiab cov tsheb tuaj yeem qhib cov tsheb nyob ntawm txoj kev ua kom ncaj.
IV. Daim Ntawv Thov Kev Pab Cuam
Asphalt txias thaj khoom siv tau siv dav los sau txoj kev tawg, kho peebsoles thiab kho cov kev daws teeb meem ntev thiab muaj zog ntev. Nws tuaj yeem siv rau kev tu ua haujlwm ntawm txoj kev, xws li kev tswj hwm, cov chaw hauv nroog, thiab cov chaw sib txuas, thiab lwm yam scenes.
Hauv cov ntsiab lus, kev kho txoj kev thiab kho cov khoom siv asphalt asphalt yog ib txoj kev tsim kho cov khoom siv nrog kev ua tau zoo thiab muaj kev cia siab thov kev cia siab.
