Cov hom hloov pauv ntawm cov cuab yeej siv tau tuaj yeem faib ua ntau hom. Hloov cov khoom me me tuaj yeem faib ua peb hom: Cov hom ua haujlwm ua haujlwm, thiab hom ua haujlwm txuas ntxiv raws li cov kauj ruam kev ua haujlwm. Rau ntau hom kev hloov kho bitumen dab tsi yog qhov yooj yim kev nkag siab txog cov khoom?

Raws li daim ntawv tshwj xeeb ntawm bitumen cov khoom siv, bitumen emulsion cov khoom muaj kev ua tau zoo. Nws muaj peev xwm ntau lawm thiab cov qauv cuam tshuam rau kev siv tshuab ntawm cov khoom siv. Cov cuab yeej no puas tuaj yeem ua phooj ywg zoo thiab txuag hluav taws xob?

Nrog rau kev txhim kho sai sai ntawm kev lag luam kev lag luam, kev loj, raws li kev txhim kho kev sib raug zoo, tau pab nyiaj txiag zoo ntau rau kev txhim kho kev lag luam. Kev noj qab nyob zoo thiab kev txhim kho kev loj yog qhov tseem ceeb hauv kuv lub teb chaws txoj kev lag luam.

Raws li cov txheej txheem sib txawv ntawm cov txheej txheem sib txawv ntawm kev hloov kho tsob ntoo asphalt ntxiv, nws tuaj yeem faib ua ob hom: batch ua haujlwm thiab ua haujlwm tas mus li. Cov khoom tso tsheb hlau luam kub tshiab yog lwm yam tshiab ntawm bitumen cov khoom tso tsheb hlau luam thiab hluav taws xob tua hluav taws xob nrawm.

Hais txog qhov ntsuas qhov tseem ceeb rau Asphalt pavement siv tau zoo, Henan Crainosun kev lag luam hnyav kev lag luam yuav piav qhia qee yam kev paub:

Asphalt kis sib txuas yog cov khoom siv txhua yam siv los hloov cov phau ntawv hnyav ua haujlwm. Hauv Asphalt kis sib kis cov tsheb, nws tuaj yeem ua tau zoo tshem tawm cov pa phem ib puag ncig thiab yog siv dav hauv ntau txoj kev tsim kho ntau thiab kev kho mob. Nyob rau tib lub sijhawm, asphalt kis tus qauv tsheb tau txais cov txheej txheem tsim nyog thiab ua kom pom tseeb tshwj xeeb thiab qhov dav. Tag nrho cov hluav taws xob tswj ntawm lub asphalt kis tsheb thauj khoom yog ruaj khov thiab ntau ntau yam. Cov kev ua haujlwm uas xav tau ntawm Asphalt kis cov tsheb thauj khoom muaj raws li hauv qab no:
