Peb lub tuam txhab muaj ntau xyoo ntawm kev paub hauv kev tsim cov khoom siv biutmen. Cov khoom siv muaj cov yam ntxwv ntawm cov kev tiv thaiv sai, tsis muaj barrel dai rau asphalt, lub cev qhuav dej zoo, kev nyab xeeb slag tshem tawm, thiab kev ntseeg tau yooj yim.

Thaum lub asphalt mixing cog yog siv, yuav ua li cas tswj cov dej noj, ua kom nws nkag siab ua ke tau zoo ib yam li asphalt sib tov nroj tsuag. Lawv yog ob qho khoom siv tshaj lij rau cov khoom siv. Txhawm rau kom ntseeg tau tias qhov zoo ntawm cov pob zeb ua tau raws cov qauv, tsis yog peb yuav tsum them sai sai ntawm cov khoom nyoos, tab sis kuj tau siv cov khoom lag luam ntawm cov pob zeb yuav tsum tau npaj.

Tus ncej kawg Foob ntawm lub tov rau asphalt tov hom, uas yog tsim los ntawm ntau txheej ntawm cov ntsaws ruaj ruaj xws li cov ntsaws ruaj ruaj xws li ntsaws ruaj ruaj xws li cov tshuab roj hmab thiab cov ntsaws ruaj ruaj. Qhov zoo ntawm lub foob cuam tshuam rau kev ua tau zoo tag nrho ntawm tag nrho cov khoom sib xyaw.

Tsis muaj teeb meem dab tsi cov khoom siv, tom qab siv nws rau ib lub sijhawm, qee qhov teeb meem loj thiab me me yuav ua rau muaj teeb meem xws li kev sib tw me me. Peb paub tias rau kev siv bitumen cua sov cua sov, kev tsim kho ntawm txoj kev tsim kho ntawm tus choj, kev xaiv ntawm txoj kev siv tshuab thiab cov khoom lag luam zoo. Cov no yog cov laj thawj tseem ceeb cuam tshuam rau lub tiaj tus ntawm txoj kev nto.

Cov kauj ruam los hloov lub stator ntawm cov zeb zeb colloid: /

1. Txo txoj kev kov ntawm cov zeb zeb zeb, tig rov qab ua rau viav vias rov qab thiab sab xis ntawm ob sab tom qab nws tau nqa nws.

Tam sim no nyob rau ntawm lub chaw tsim kho, suav nrog kev tsim kho kev tsim kho tshuab, ib qho ntawm cov khoom siv siv yog asphalt tov cog. Nws tuaj yeem hais tias nws tuaj yeem siv rau ntau qhov sib xws thiab cov teb, thiab nws tuaj yeem muab qee yam kev pab rau kuv lub teb chaws cov qauv kev tsim kho. Ntawm chav kawm, hauv cov txheej txheem ntawm kev siv, nws yog qhov tsim nyog los ua txoj haujlwm zoo hauv ntau qhov, yog li siv cov nroj tsuag tov tuaj yeem muaj kev nyab xeeb dua.
