Asphalt nroj tsuag yog cov khoom tseem ceeb hauv kev tsim kho thiab txij nkawm, ua ke, sib xyaw, thiab ua kom zoo nkauj, ua kom muaj kev cai Asphalt uas tau ua raws li cov haujlwm. Lawv cov kev tswj kom sov thiab kub ua kom muaj peev xwm ua tau zoo dua qub txhim kho qhov zoo thiab ruaj khov ntawm asphalt mixtures. Siv dav hauv infrastructure tej yaam num xws li txoj kev loj, lawv ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa kev thauj mus los thiab ua kom zoo ntawm txoj kev ua haujlwm zoo.
Asphalt nroj tsuag, raws li qhov tseem ceeb ntawm txoj kev kev tsim kho kev tsim kho, muaj lub luag haujlwm npaj kev siv asphalt asphalt, cov khoom siv tseem ceeb. Hauv kev tsim kho loj, siab {- Zoo Equalt sib tov yog qhov tseem ceeb ntawm txoj kev durability, thiab tsav kev nplij siab. Cov haujlwm tseem ceeb ntawm asphalt nroj tsuag tau cuam tshuam hauv cov chaw tseem ceeb hauv qab no:
Asphalt ua: cov haujlwm tseem ceeb ntawm asphalt nroj tsuag yog kom ua haujlwm asphalt. Siv cov cua sov ua tau zoo, asphalt, uas yog cov khoom khov los yog semi- pa dej kub, ua haujlwm zoo rau kev ua kom zoo rau kev ua tiav. Lub chaw tseem ceeb ntxiv cov chaw cia khoom siv tau cov chaw asphalt hauv kev sib txuas ua ke thiab tiv thaiv kev cuam tshuam vim kev cuam tshuam dab tsi rau kev ua haujlwm sophalt.
Aggregate Ua: ntau yam aggregates, xws li gravel thiab xuab zeb, yog qhov meej meej. Cov tshuaj ntsuam, kev ntsuas, thiab kev sib xyaw ua ke ntawm kev sib txawv ntawm kev sib txawv raws li kev tsim kho cov qhab nia. Cov cuab yeej kuaj xyuas qib siab yog cov khoom sib xyaw ua ke ntawm txhua qib ua tau raws cov qauv qauv thiab ua tau haujlwm ruaj khov ntawm kev ua haujlwm ntawm asphalt. Thaum lub sij hawm thauj mus los, muaj txiaj ntsig kev thauj khoom siv tau siv kom nrawm dua thiab raug xa cov txheej txheem sib xyaw ua ke rau cov chaw sib xyaw, sib ntsib cov kev xav tau ntawm kev tsim khoom txuas ntxiv.
Kev sib xyaw: ua tiav kev sib xyaw ntawm asphalt thiab aggregeg yog qhov tseem ceeb. In a specially designed agitator, asphalt and aggregate are thoroughly blended under high-temperature, high-speed mixing. Los ntawm kev ua kom zoo xws li cov duab, kaum sab xis, thiab nrawm ntawm cov kab ke uas aslyly coated ntawm lub ntsej muag sib xyaw, ua rau muaj kev sib xyaw zoo nkauj nrog kev ua tau zoo heev. Qhov kev sib xyaw ua ke no sib xyaw ua ke sib xyaw ua ke sib xyaw ua ke, thiab kev tawm tsam zoo heev, thiab kev tawm tsam dej ua kom zoo, ua tau zoo txuas lub neej ntawm txoj kev tom qab paving.
Kev tswj kom zoo: nruab nrog cov series ntawm kev ntsuas kev tswj hwm zoo. Ib qho kev tswj hwm qhov kub thiab txias thiab hloov kho qhov kub ntawm asphalt, thiab tiv thaiv cov kev hloov pauv ntau ntxiv los ntawm kev hloov pauv hloov pauv ntawm kev cuam tshuam cov sib tov zoo. Daim ntawv qhia txog kev siv hluav taws xob kom raug yog tswj tau cov khoom nyoos, xws li asphalt thiab agregate, kom assuring qhov tseeb ntawm cov sib xyaw sib xyaw. Tsis tas li ntawd, cov cuab yeej ntsuas zoo yog nruab rau kev coj ua tiag tiag {3} Thaum muaj ntau yam txuj ci ua tiav kev sib xyaw ua tiav, ntws tau muaj txiaj ntsig, thiab cov ntsiab lus tsis muaj txiaj ntsig. Yog tias muaj ib qho teeb meem zoo tau tshawb pom, cov tsis muaj peev xwm tuaj yeem hloov kho kom sai li kom ntseeg tau tias qhov zoo ntawm asphalt sib xyaw ua kom tiav cov kev xav tau.
