Qalab kala duwan ayaa fure u ah in la bilaabo wax soo saarka. Farsamayaqaannada xirfadleyda ah ee Gaoyuan ayaa ku bari doona tallaabooyinka bilawga ah ee qalabka emulsion bitumen, iyagoo rajeynaya inay bixiyaan hawlgal ku habboon wax soo saarka:
1. Fur furaha daamurka oo fur waalka ka baxa taangiga isku darka emulsifier.
2. Bilow emulsifier-ka, isla markaana, emulsifier-ga lama kululayn, oo isha kuleyliyaha (hagaha saliidda ama uumiga) waa la damiyay.

3. Bilow bamka gear emulsifier, oo qiyaas xawaaraha lagu dejinayo 60-100 rpm
4. Ku dheji qalabka daamurka 360-500 rpm
5. Hagaaji farqiga u dhexeeya stator iyo rotor ee emulsifier-ga. Guud ahaan, qaybaha asfaltku waa kuwa yaryar intii suurtagal ah. Iyadoo la tixgelinayo nolosha adeegga emulsifier iyo stator, waxay kuxirantahay culeyska, ilaali kormeerka codka ee mashiinka, samee ammeter. Qiimaha hadda waa inuu ka yaraado 29a. Inta lagu jiro habka wax soo saarka, marka heerkulku kordho, jidhku wuu balaadhin doonaa, waxayna u badan tahay inuu dib u hagaajiyo farqiga (guud ahaan, gaabyada stator iyo rotor ee emulsifier ayaa lagu hagaajiyay warshadda).
6. Bilow bamka gaarsiinta alaabta.
Dhowr tillaabo oo fudud oo tixraac ah, sii wad inaad fiiro gaar ah u yeelato madalkeena, wax badan oo akhrin ah ayaa laguu soo bandhigi doonaa.
