Asphalt nws cov khoom siv asphalt yog lub tshuab siv los loj ua asphalt qhob. Vim tias nws cuam tshuam los ntawm ntau yam los ntawm ntau yam thaum lub sijhawm cov txheej txheem ntau lawm, nws yuav tsis muaj qee cov teeb meem tom qab siv. Niaj hnub no, lub rooj sab laj yuav qhia rau koj cov hau kev ntawm kev kho cov khoom puas ntawm asphalt sib tov ua khoom siv.

Asphalt sib xyaw ua ke cov khoom siv tau ntsib cov teeb meem sib txawv, thiab nws cov kev daws teeb meem kuj txawv. Piv txwv li, ib qho ntawm cov teeb meem asphalt ntawm asphalt tov khoom yog qhov tsis muaj zog thiab kev puas tsuaj ntawm qhov chaw. Nyob rau lub sijhawm no, cov qauv tsim nyog yog pib txhim kho los ntawm kev tsim khoom ntawm qhov chaw.
Asphalt sib xyaw ua ke cov khoom siv nres tsheb tuaj yeem hloov kho los ntawm kev txhim kho lub smoothness ntawm cov ntu seem hla-kev lim dej kom txo tau cov kev ntxhov siab ntawm qhov chaw. Nitriding thiab kev kho cua sov kuj tseem siv tau los txhim kho kev ua haujlwm ntawm asphalt tov khoom siv. Cov hau kev no tuaj yeem txo cov nyhuv ntawm kev nkees thiab kev puas tsuaj.
Ntxiv nrog rau qhov chaw qaug zog, asphalt sib xyaw khoom yuav tseem yuav pom qhov sib txawv vim kev sib txhuam. Lub sijhawm no, cov khoom siv-resistant yuav tsum tau siv kom ntau li ntau tau, thiab qhov tshwm sim ntawm kev sib txhuam yuav tsum tau txo kom ntau li ntau tau hauv cov duab asphalt sib tov khoom siv. Yog tias cov khoom siv tau ntsib qhov chaw puas tsuaj los ntawm kev corrosion, tom qab ntawd cov khoom siv tiv thaiv xeb xws li chromium thiab zinc tuaj yeem siv rau phaj ntawm cov hlau seem. Txoj kev no tuaj yeem ua lub luag haujlwm ntawm kev tiv thaiv qhov chaw corrosion.
