Kev txiav txim siab cov khoom yog ib theem tsim nyog nyob rau hauv cov txheej txheem txheej txheem ntawm asphalt sib tov, thiab nws tseem yog ib qho ntawm cov khoom tseem ceeb tshaj plaws, vim tias muaj kev pabcuam lub neej ntawm tag nrho cov khoom siv. Feem ntau, thaum peb txiav txim siab cov khoom siv ntawm lub tshuab, peb feem ntau siv cov yam ntxwv ntawm kev ua haujlwm nruab nrab yog qhov asphalt sib xyaw cog yog qhov tseeb tib yam.

Yog tias tsis muaj cov kev xav tau tshwj xeeb, cov hlau sib xyaw zoo sib xws yog ua rau cov pa roj carbon hlau feem ntau yog li qhov kub tshaj 350 ℃, thiab tus nqi yog tsawg. Txawm li cas los xij, kev sib xyaw ua ke ntawm cov nroj tsuag tsis tuaj yeem siv cov khoom siv no. Asphalt yog ib yam tshuaj nrog cov kev ua kom sov zoo, nws tsis tau raws li qhov yuav tsum tau ua nyob rau hauv cov nqe lus ntawm kev kub siab tiv taus, thiab carbon steel muaj kev tsis zoo corrosion.
Hauv kev pom ntawm cov dej num saum toj no, stainless hlau asphalt mixers lossis cov ntaub ntawv kab khob yuav siv tau. Tab sis tsis muaj teeb meem dab tsi ib, muaj ntau cov ntaub ntawv qhia ntxaws ntxiv, yog li cov qauv tshwj xeeb yuav tsum tau txiav txim siab raws li nws cov kev sib xyaw ua ke, sib tov txias thiab corrosiveness.
