Asphalt mixing nroj tsuag yog ib qho ntawm cov khoom siv tseem ceeb tshaj plaws rau kev tsim cov khoom asphalt. Yog hais tias nws ua tsis tau, cov zis ntawm cov khoom yuav inevitably txo. Qhov no yog lub nra hnyav uas tsim nyog yuav tsum tau saib xyuas, yog li muaj teeb meem dab tsi tshwm sim hauv asphalt sib xyaw cov nroj tsuag?

Feem ntau yog cov khoom lag luam tsis ruaj khov thiab kev ua haujlwm qis ntawm cov khoom siv. Tom qab kev txheeb xyuas, nws paub tias cov laj thawj tseem ceeb rau hom kev ua tsis tiav no yog raws li hauv qab no:
1. Kev faib ua feem ntawm cov khoom siv tsis raug;
2. Cov khoom siv raw khoom tsis zoo;
3. Cov nqi hluav taws xob qis hauv cov khoom siv;
4. Kev teeb tsa tsis raug ntawm cov cuab yeej ua haujlwm tsis zoo.
Tom qab txiav txim siab qhov laj thawj twg yog qhov ua rau, coj cov kev daws teeb meem sib xws.
Ntxiv nrog rau kev ua haujlwm qis, qhov tso tawm qhov kub thiab txias ntawm asphalt mixing cog yog qee zaum tsis ruaj khov thiab tsis tuaj yeem ua tau raws li qhov xav tau ntawm qhov kub thiab txias. Qhov ua rau ntawm qhov teeb meem no yog qhov ntsuas kub tsis raug, thiab qhov loj ntawm cov nplaim taws yuav tsum tau hloov kho kom zoo dua qhov teeb meem no.
