Thaum xaiv cov cuab yeej siv, peb yuav tsum saib tus nqi ua tau zoo ntawm cov khoom siv thiab kev ua haujlwm ua haujlwm. Tom qab ntawd cov emulsification chav siv nyob rau hauv cov khoom siv emulsification tseem ceeb dua rau cov khoom siv ntau lawm. Cia peb saib ntawm tus txheej txheem ua hauj lwm ntawm pawg emulsification.

Asphalt sib tov ua nroj tshuag cog yog mas tsim ntawm cov kab ke, cov khoom siv hluav taws xob, cov khoom siv kub, cov khoom siv tshem tawm, tsis siv neeg tswj hwm.

Cov ntaub ntawv siv hauv asphalt mixtures muaj ntau hmoov av. Thaum cov khoom siv ua haujlwm, yog tias cov hmoov av nkag mus, nws yuav ua rau muaj kuab paug. Yog li ntawd, cov cuab yeej tshem tawm plua plav yuav tsum tau muab ntsia, thiab tam sim no lub hnab plua plav tshem tawm yog txoj kev tseem ceeb. Kev nyab xeeb yog qhov teeb meem kev txiav txim siab. Muaj cov txheej txheem kev nyab xeeb zoo.

Nrog kev yuav tsum tau ua kom muaj zog ceev kom tsim tau lub neej zoo thiab paub txog kev txhim kho tshiab, kev tsheb tsheb hauv tsheb muaj ntau dua thiab tseem ceeb dua. Yooj yim thiab ua tau zoo txheej txheem txaus, txuag, txuag asphalt cov khoom siv tau ua rau tib neeg lub siab, thiab kev txhim kho cov khoom siv asphally, thiab kev txhim kho cov khoom siv asphally, thiab kev txhim kho cov khoom siv asphalt Cov khoom siv inehalt yog siv rau tshav kub yaj asphalt thiab tawg asphalt hauv dej nrog cov khoom me me los ua ib qho emulsion. Feem ntau ntawm lawv tam sim no nruab nrog xab npum kua tso tsheb hlau luam, yog li ntawd xab npum ua kua tuaj yeem raug muab faib rau hauv cov zeb zeb colloid.

Sinoroadoer Kev siv kho thiab kho cov neeg siv tshuab kis las, peb tau tas li tshiab thiab txhim kho cov khoom siv khoom lag luam. Ntawm no peb xav qhia peb lub tuam txhab cov khoom hauv kev nthuav dav:

Nrog zoo tsim kev sib xyaw thiab kev tsim kho cov xwm txheej, lub durability thiab kub ruaj khov ntawm kev ua asphalt ntawm kev txhim kho. Yog li no, sbs asphalt thiab dechalt asphalt muaj cov kev yuav sib txawv hauv kev thauj mus los, chaw cia khoom thiab kev siv deg. Tsuas yog siv raug kho xwb tuaj yeem ua tiav cov nyhuv xav tau.
