Cov xwm txheej ua haujlwm ntawm asphalt sib tov cog muaj feem xyuam rau ntau yam. Txhawm rau kom txuag tau lub zog noj ntawm cov asphalt mixed nroj tsuag, cov neeg ua haujlwm yuav tsum nrhiav cov kev daws teeb meem los ntawm cov teeb meem tau ntsib hauv kev ua haujlwm tiag tiag.
Ua ntej tshaj, kho cov ntsiab lus ya raws thiab qhov loj ntawm cov pob zeb hauv cov chaw nres tsheb asphalt sib tov.

Hauv kev ua haujlwm ntawm asphalt mixing noj, muaj ntau cov roj yuav tsum tau noj, thiab cov ntsiab lus noo nyob hauv cov ntaub ntawv raw yuav muaj feem xyuam rau cov peev txheej ntawm cov peev txheej. Raws li kev txheeb cais, txhua zaus cov neeg noo noo ntawm cov pob zeb nce los ntawm ib qho feem pua ​​ntawm cov khoom siv yuav nce li ntawm 12%. Yog li ntawd, yog tias koj xav txuag hluav taws xob tau siv hluav taws xob, tom qab cov neeg ua haujlwm yuav tsum tswj hwm cov ntaub ntawv noo noo, thiab tuaj yeem siv qee qhov kev ntsuas kom zoo ntawm cov khoom siv raw.
Tom qab ntawd cov kev ntsuas uas yuav tsum tau ua yog:
1. nruj tswj cov khoom zoo kom tsis txhob cuam tshuam rau kev tsim khoom tom qab;
2. Rhais cov vaj tse kom txhim kho qhov muaj peev xwm ntawm lub xaib thiab txo cov ntsiab lus ya raws li ntau tau, yog li kev txhim kho kev ua haujlwm ntawm asphalt tov. Txuag roj noj ntawm asphalt sib tov chaw nres tsheb;
3. Tswj qhov loj ntawm pob zeb.
Thib ob, xaiv cov roj kom tsim nyog rau Asphalt sib tov cog.
Xaiv cov roj xis yog qhov tseem ceeb rau kev txhim kho kev sib txuas ua ke ua haujlwm. Feem ntau cov roj hauv kev ua lag luam niaj hnub no suav nrog: Ua kua roj, gaseous ruels, thiab khoom roj. Hauv kev sib piv, cov roj muaj cov kev sib txuas ua haujlwm siab, muaj txiaj ntsig siab hauv siab, thiab tsis ruaj khov. Qhov tsis zoo yog tias tus nqi siab dua, yog li nws feem ntau siv hauv kev sib xyaw me me thiab nruab nrab ntawm asphalt xyaw. Khoom roj tau muaj kev ruaj khov tsis zoo, tuaj yeem yooj yim ua rau muaj kev huam yuaj, thiab yog tsis yooj yim los tswj nws qhov kub, yog li nws tsis tshua siv. Liquid fuel has high calorific value, low impurity content, good controllability, and relatively cheap cost.
Thib peb, kho cov roj atomization ntawm lub xeev ntawm asphalt sib tov chaw nres tsheb.
Cov nyhuv atomization ntawm cov roj kuj cuam tshuam nrog cov teeb meem kev siv hluav taws xob. Yog li no, tswj tau ib lub xeev atomization zoo yuav txhim kho kev siv roj kev ua haujlwm tau zoo. Feem ntau, cov chaw tsim khoom yuav hloov kho lub xeev atomization hauv lub sijhawm, yog li cov neeg ua haujlwm los ntawm kev sib xyaw asphalt
