Habka diyaarinta ee qalabka bitumen ee wax laga beddelay, xakamaynta heerkulka ayaa aad muhiim u ah. Haddii heerkulku uu aad u hooseeyo, qaniinyada ayaa noqon doonta dhumuc weyn, dareere yar, oo ay adagtahay in la soo saaro; haddii heerkulku uu aad u sarreeyo, dhinaca kale, waxay keenaysaa in bitumen ay gabowdo. Isla mar ahaantaana, heerkulka gelitaanka iyo ka-soo-baxa qashin-qubka emulsified wuxuu noqon doonaa mid aad u sarreeya, taas oo saameyn doonta xasilloonida emulsifier-ga iyo tayada bitumen-ka emulsified. Waxa kale oo ay tahay in qof kastaa fahmo waa in bitumen ay tahay qayb muhiim ah oo ka mid ah bitumen-ka emulsified, oo guud ahaan xisaabiya 50%-65% wadarta tayada bitumen-ka.

Marka la buufiyo ama la qaso qaniinyada emulsified, waxaa la damiyaa bitumen-ka emulsified, ka dib markii biyaha ku jira ay soo baxaan, waxa dhabta ah ee dhulka ku hadhay waa bitumen. Sidaa darteed, diyaarinta bitumen ayaa si gaar ah muhiim u ah. Intaa waxaa dheer, qof kastaa waa inuu sidoo kale ogaadaa in marka geedka bitumen ee emulsified la soo saaro, viscosity of bitumen ayaa hoos u dhacaya marka heerkulku kordho. Kor u kaca 12°C kasta, viscosity-kiisa firfircoon wuxuu ku dhawaad ​​labanlaabmaa.
Inta lagu jiro wax soo saarka, bitumen saldhigga beerashada waa in marka hore la kululeeyo si dareere ka hor emulsification la fulin karo. Si loola qabsado awoodda emulsification ee micronizer-ka, viscosity firfircoon ee bitumen-ka saldhigga beerashada guud ahaan waxaa lagu xakameynayaa inuu noqdo 200 cst. Heerkulka hoose, ayaa kor u kacaya viscosity, markaa bamka bitumen wuxuu u baahan yahay in la cusboonaysiiyo. iyo cadaadiska micronizer-ka, laguma dayi karo; laakiin dhinaca kale, si looga fogaado uumiga iyo uumiga biyaha badan ee alaabta la dhammeeyey inta lagu guda jiro wax soo saarka ee Emulsified bitumen, taas oo u horseedi doonta demulsification, iyo sidoo kale ay adag tahay in la kululeeyo substrate beerashada bitumen aad u sarreeya. micronizer guud ahaan waa la isticmaalaa. Heerkulka alaabta la dhammeeyey ee albaabka laga soo galo iyo ka bixista waa inuu ka hooseeyaa 85°C.
