Asphalt khoom ua si lub luag haujlwm tseem ceeb hauv kev kev siv.
Ua ntej, asphalt cov khoom siv tau zoo tsim cov khoom siv asphalt. Nws sib tov ntau cov ntaub ntawv raw, xws li asphalt, crushed hmoov, nyob rau sab xis ua proportions, kom muaj kev sib xws, ua kom zoo nkauj thiab sib xyaw ua ke zoo. Qhov no yog qhov tseem ceeb rau cov thauj khoom - kev coj tus kabmob thiab kev ruaj khov ntawm txoj kev. High -} Cov sib xyaw ua tau zoo tiv thaiv cov kab nrib pleb, peebsoles, thiab lwm yam kev puas tsuaj dhau mus, ntau dua kev siv txoj kev ua haujlwm lub neej.
Thib ob, loj- nplai ntau zog muaj peev xwm ntawm asphalt cov khoom siv tau raws li kev xav tau ntawm txoj kev kev tsim kho. Loj - teev txoj kev yuav tsum muaj ntau ntau ntawm asphalt sib tov. Cov khoom siv asphalt tuaj yeem tsim lawv sai sai thiab tsis tu ncua, txhim kho kev tsim kho cov txiaj ntsig thiab txuag sijhawm thiab nqi. Tsis tas li ntawd, nws cov kev ua haujlwm siab ntawm kev siv tshuab thiab qhov yooj yim kev ua haujlwm txo cov kev cuam tshuam ntawm kev tiv thaiv kev siv zog, thiab txhim kho kev nyab xeeb kev nyab xeeb.
Tsis tas li ntawd, cov cuab yeej siv asphalt tuaj yeem kho cov tsis tau tsim kom tau raws kev tsim qauv sib txawv. Piv txwv li, kev sib tov sib tov thiab cov khoom ntawm cov sib tov tuaj yeem kho raws li cov seem ntawm txoj kev xws li cov seem ntawm txoj kev ntawm txoj hauv kev thiab qib.
Tsis tas li ntawd, cov khoom siv tau ua tiav yog ib puag ncig phooj ywg. Nws siv roj zoo zoo thiab hmoov av los ntawm cov txheej txheem ntau lawm, txo cov pa phem ib puag ncig thiab sib ntsib hauv ntiaj teb kev tiv thaiv.
Hauv ntej, Asphalt cov khoom siv ua lub luag haujlwm tseem ceeb hauv kev kev siv. Los ntawm kev sib xyaw ntawm cov khoom nyoos rau kev tsim cov khoom tiav, nws muaj qhov cuam tshuam zoo ntawm txoj kev zoo thiab tsim kev siv tau.
