Asphalt sib xyaw ua ke ib qho kev ua haujlwm tseem ceeb thaum lub sijhawm tsim cov khoom lag luam asphalt raw khoom. Cov qauv ntawm cov khoom siv no yog qhov yooj yim thiab tsim nyog, thiab nws ua tau raws kev ua haujlwm ntawm kev lag luam niaj hnub. Yog li no, ntau qhov chaw muaj kev lag luam tam sim no siv asphalt mix nroj tsuag kom tiav cov kev tsim khoom thiab kev tsim khoom ntawm asphalt. Tam sim no, txhawm rau pab kom muaj kev lag luam sib txawv kom ua tiav kev ua haujlwm tau zoo thaum siv cov cuab yeej siv, kev faib tawm cov khoom siv tau nce ntxiv. Tam sim no txawb thiab txhim kho cov khoom siv asphalt siv tau siv dav thiab kev ua tiav cov khoom siv asphalt ntawm kev siv qhov chaw nyob thaum lub sijhawm siv, yog li nws tsis yoog raws li cov khoom siv txawb.

Yog li dab tsi yog qhov zoo ntawm cov khoom siv hluav taws xob asphalt sib tov ua ke? Ntau cov khoom lag luam tam sim no tsom rau cov khoom siv txawb thaum cov khoom siv asphalt Cov kev sib xyaw nrog cov khoom siv hauv cov khoom siv tau siv cov qauv tsim qauv, yog li kev ua haujlwm ntawm cov pa tau ruaj khov thiab txhim khu kev qha thaum ua haujlwm, thiab kev ua haujlwm tseem ceeb yog kuj tseem muaj zog.
Thaum lub sij hawm ua ntau lawm cov asphalt sib tov cog, lub vijtsam vibrating kuj tseem ntxiv. Qhov sib ntxiv ntawm cov cuab yeej no tuaj yeem txhim kho kev ua haujlwm ntawm cov cuab yeej siv thiab siv tau zoo tsis txhob muaj qhov tshwm sim ntawm kev ua tsis zoo. Thaum lub sijhawm ua haujlwm ntawm cov khoom siv, cov txheej txheem ziab thiab lwm yam haujlwm ua haujlwm tiav los ntawm lub hnab plua plav tshem tawm cov cuab yeej tshem tawm. Txoj kev tsim qauv no tseem zoo zam qhov poob ntawm cov cua sov thiab txhim kho lub zog ua haujlwm tag nrho.
Tam sim no kev nqis peev thiab application ntawm asphalt sib xyaw cov nroj tsuag tau muab cov kev mob yooj yim rau ntau yam lag luam ntau lawm. Cov khoom siv muaj kev ua tau ruaj khov, cov thev naus laus zis siab dua, thiab tuaj yeem txuag lub zog, yog li tus nqi siv yuav siab dua rau yav tom ntej.
