Ob hom ntawm asphalt mixing nroj tsuag muaj nuj nqi los yog kev ua haujlwm zoo sib xws. Lub hauv paus ntsiab lus ntawm txhua hom asphalt cog yog tib yam piv txwv li los tsim cov kub sib tov asphalt. Qhov sib txawv nyob rau hauv txoj kev uas cov khoom kawg yog npaj. Qee qhov kev ua haujlwm ntawm ob hom asphalt nroj tsuag yog:
- Ntau qhov sib txawv ntawm cov khoom ntim khoom thiab pub rau hauv cov thawv.
- Kev ntsuam xyuas ntawm cov sib sau ua ke. Hauv hom nruam cov aggregates raug tshuaj xyuas kom tshem tawm ntau dhau. Thaum nyob rau hauv batch hom cov aggregates raug tshuaj xyuas kom cais lawv mus rau hauv sib txawv compartments.
- Qhuav thiab cua sov ntawm aggregates.
- Melting cia thiab hloov bitumen
- Kev khaws cia thiab hloov pauv cov ntaub ntawv muab tub lim.
- Bitumen, aggregates thiab muab tub lim cov ntaub ntawv yog hnyav nyob rau hauv batch hom nroj tsuag. Qhov twg hauv cov nroj tsuag tsis tu ncua lawv tau ntxiv thiab tswj los ntawm kev hloov pauv zaus.
- Tshem tawm cov kub sib tov asphalt mus rau hauv lub tsheb lossis lub chaw cia khoom.
- Tswj vaj huam sib luag yog ib txwm muaj rau ob hom. Nws tswj cov kev ua ub no ntawm cov nroj tsuag thiab muab peb cov lus ceeb toom ntawm cov tsis tseem ceeb.
Plaub Yam Tseem Ceeb ntawm Asphalt Mixing Cog Ua Haujlwm:
Muaj qee qhov hauv paus uas muaj rau txhua qhov asphalt sib xyaw cov nroj tsuag. Lawv yog cov hauv qab no:
- Qhuav thiab cua sov ntawm aggregates.
- Qhov hnyav ntawm aggregates, bitumen thiab muab tub lim.
- Sib tov aggregates nrog bitumen thiab muab tub lim.
- Tso cov kub sib tov asphalt.
Hauv txhua hom asphalt cog qhov tseeb ntawm qhov hnyav yog qhov tseem ceeb. Yuav tsum muaj qhov sib npaug thiab raug qhov hnyav ntawm cov aggregates, bitumen thiab minerals. Thaum qhov hnyav sib xws, peb tau txais cov khoom kawg uas xav tau uas yog raws li qhov kev cia siab thiab cov qauv. Nws pab tsim txoj kev zoo dua raws li cov cai teev tseg. Cov nroj tsuag asphalt muaj peev xwm khaws cov zaub mov txawv. Peb tuaj yeem hloov pauv siv cov zaub mov txawv rau cov ntawv thov sib txawv raws li qhov xav tau. Txawm hais tias nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias kev khaws cia thiab kev siv ntau yam zaub mov txawv yog qhov tseem ceeb thaum koj cuam tshuam nrog ntau tus neeg siv khoom. Thaum koj muaj zaub mov txawv ntawm cov neeg siv khoom sib txawv khaws cia nrog koj, nws yooj yim los xaiv cov ntawv qhia tshwj xeeb uas xav tau. Thaum daim ntawv qhia xav tau raug xaiv nrog ob peb clicks nws muaj peev xwm ua rau AMP tsim cov khoom zoo ntawm kub sib tov asphalt.
Kev vam meej ntawm ib qho asphalt mixing cog yuav tsum muaj kev sib npaug txaus thiab kev sib koom ua ke ntawm tag nrho cov khoom. Txij li thaum asphalt cog yog kev sib xyaw ua ke ntawm cov khoom siv tshuab thiab hluav taws xob. Nws yog ib qho tseem ceeb uas tag nrho cov Cheebtsam ua hauj lwm nyob rau hauv tandem muab cov kev xav tau. Nws yog qhov ua tau kom tau txais kev sib npaug thiab sib npaug los ntawm kev soj ntsuam ceev faj thiab kev tswj hwm. Nws yog ib qho tseem ceeb los xyuas tag nrho cov khoom cog ua ntej pib. Nws yog ib qho tseem ceeb uas yuav tsum tau ua txhua hnub, txhua lub lim tiam, kev saib xyuas txhua hli raws li tau piav qhia los ntawm cov chaw tsim khoom ib ntus. Tag nrho cov khoom xws li aggregates, roj, bitumen yuav tsum tau kuaj xyuas kom zoo ua ntej siv. Thaum ceev faj tau pom nws yog ib qho yooj yim los ua cov khoom sib tov zoo los ntawm cov nroj tsuag kub sib tov ntawm txhua lub tuam txhab zoo.
Atlas yog Is Nrias teb raws li cov chaw tsim khoom thiab xa tawm ntawm asphalt tov cog.
Dab tsi yog cov khoom sib xyaw ntawm kub asphalt?
Kub mix asphalt muaj cov pob zeb sib txawv, pob zeb, bitumen thiab cov khoom siv khi. Kub mix asphalt yog npaj los ntawm cua sov bitumen, aggregates thiab sib tov nyob rau hauv siab kub.
Dab tsi yog 2 hom asphalt?
2 yam tseem ceeb ntawm asphalt yog kub mix thiab txias mix hom. Kub mix asphalt yog npaj kub thiab pw ua ntej nws txias. Kev sib xyaw txias asphalt tsis yog cua sov - nws yog tsim los ntawm kev sib xyaw emulsion, dej thiab cement. Aggregates siv nyob rau hauv txias mix asphalt yog unheated.
Dab tsi yog qhov txawv ntawm asphalt thiab bitumen?
Bitumen yog cov khoom siv raw khoom siv los tsim cov khoom kub asphalt. Asphalt yog kev sib xyaw ntawm aggregates, xuab zeb thiab bitumen ntawm qhov kub thiab txias. Bitumen ua raws li cov khoom siv hauv kev tsim cov asphalt cement.
