Thaum lub sij hawm kev tsim kho txoj kev, asphalt mixers yog khi rau siv, thiab txhua leej txhua tus yuav tsum paub txog qhov no. Ntxiv rau qhov zoo ntawm lub tshuab tag nrho, kev xaiv thiab siv cov khoom siv kuj tseem ua lub luag haujlwm tseem ceeb, uas yuav cuam tshuam rau kev tsim kho thiab cov nqi tsim khoom. Siv lub vijtsam hauv asphalt tov khoom ua piv txwv rau cov lus piav qhia ntxaws.

Tsis muaj teeb meem dab tsi ntawm cov khoom sib xyaw ua ke nws yog, yog tias qhov zoo ntawm cov khoom siv hlau ntawm vibrating npo mesh, qhov tsim nyog loj ntawm lub mesh thiab mesh qhov, thiab qhov tseeb ntawm lub mesh tsis raug coj mus rau qhov tseeb, qhov sib xyaw ua haujlwm yuav tsis ua. ua kom zoo ua ntej. Qhov no ntxiv cuam tshuam rau kev siv asphalt. Yog li ntawd, kev xaiv cov ntxaij vab tshaus zoo thiab hnav-tiv taus yog qhov yooj yim rau kev sib xyaw cov khoom siv high-yield thiab high-zoo asphalt, thiab nws kuj tuaj yeem txo cov nqi.
Qee lub tuam txhab asphalt tov khoom siv lub tshuab tsim khoom siv cov ntxaij vab tshaus ua los ntawm cov hlau zoo tib yam uas pheej yig dua thiab tsis quav ntsej cov kev cai tshwj xeeb hnav-resistant steel hlau braiding thiab cov txheej txheem edging, uas ua rau lub neej luv luv thiab cuam tshuam rau kev ua haujlwm ntawm lub tsev.
