Nws tseem yog qhov tseem ceeb rau kev saib xyuas txhua hnub thiab saib xyuas ntawm asphalt sib tov nroj tsuag. Qhov ntau ntawm cov plua plav yuav tsim tawm thaum lub sijhawm ua haujlwm. Yog tias cov hmoov av no poob rau ntawm cov khoom tseem ceeb ntawm cov khoom siv, lawv yuav cuam tshuam rau cov haujlwm ntawm cov khoom siv. Cov cuab yeej yuav muaj nyob rau hauv zoo kawg thauj thaum nws nyob hauv qab kub thiab ua haujlwm txuas ntxiv mus ntev. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau ntub cov khoom siv, khij lub ntsuas hluav taws xob vibrating, roj av, pub xa hluav taws xob, thiab ntxuav lub qhov rooj paug. Qhov no tuaj yeem ua kom muaj kev ua haujlwm ib txwm ntawm cov cuab yeej siv, txhim kho cov kev sib xyaw zoo li asphalt sib tov, thiab txuas ntxiv cov kev pabcuam lub neej ntawm cov khoom siv.

Nrog kev tsim kho tas mus li ntawm cov kev tsim kho qib high-qib kev txhim kho thiab kev sib dhos thiab cov khoom siv rho tawm ntau ntxiv kuj tau txhim kho maj. Rau kev teeb tsa ntawm loj-teev asphalt tov cov nroj tsuag, nws yog ib qho tsim nyog kom them sai sai rau kev xaiv thiab cov txheej txheem kev teeb tsa ntawm lub hauv paus thiab khoom siv. Nyob rau tib lub sijhawm, nrog kev hloov ntawm txoj kev tsim kev tsim kho txoj kev tsim kho, nws tseem tsim nyog yuav tsum tau ua tiav cov khoom siv tau ua tiav, uas muaj cov yam ntxwv ntawm kev ua haujlwm yooj yim thiab ua haujlwm siab ua haujlwm.
Feem ntau, raws li cov cuab yeej siv tseem ceeb, asphalt sib xyaw ua ke ib cov nroj tsuag ua si lub luag haujlwm tseem ceeb hauv kev tsim kho. Los ntawm kev teeb tsa tsim nyog, kev tswj kev nyab xeeb txhua hnub thiab txij nkawm, peb tuaj yeem ua haujlwm zoo rau kuv lub teb chaws txoj kev siv tsheb thauj khoom.
