Rau cov neeg siv khoom siv, cov khoom siv siv yog qhov tseem ceeb ntawm txhua tus neeg siv. Peb yuav tsum xa cov tseem ceeb rau qhov txuas no hauv cov txheej txheem ntau lawm. Cov chaw tsim khoom hauv lub rooj huv sab laj tom qab no yuav tshawb xyuas qhov ntau ntawm emulsifier siv.

Thaum lub emulsified asphalt cov khoom siv yog emulsifying asphalt, tus asphalt kub yog qhov zoo dua nyob rau saum 130 ° C kom muaj kev zoo dua qub; 2. Qhov nyiaj ntawm emulsifier feem ntau yog 8-14 ‰ ntawm emulsified asphalt, asphalified asphalt (asphalt cov ntsiab lus ntau dua 50%), thiab qhov kub yog 60-70 ° C. Cov emulsifier yuav tsum tau siv nyob rau hauv nruab nrab thiab sab saud ntawm kev tsim khoom, 10 kg ib tuj ntawm emulsified asphalt, lossis 20 kg ib tuj dej (asphalt cov ntsiab lus yog 50%); Tus nqi ntawm yuav-3 emulsifier feem ntau yog 18-25 ‰ ntawm emulsified asphalt (18-25kg ib tuj ntawm emulsifi cov ntsiab lus kub yog 60-70 ° C. Cov emulsifier yuav tsum tau siv nyob rau hauv lub sauv thiab qis txwv ntawm cov tshuaj rau thawj zaug tsim tawm kom ua tiav ntau lawm. 24 kg ib tuj ntawm emulsified asphalt, lossis 48 kg ib tuj ntawm dej (50% asphalt cov ntsiab lus), tuaj yeem txo raws li cov kev mob tiag tiag tom qab kev tsim nrawm.
