The temperature of the emulsion during production is -95-85 degrees Celsius below 100 degrees Celsius
The total temperature of the two phases for the emulsion with bitumen 60: 195 degrees Celsius, the viscosity of the bitumen should be less than 2 poise.

Types of emulsions
Cationic emulsion:
If an electric potential is established between two electrodes immersed in an emulsion containing particles with a positive charge of bitumen, they migrate towards the cathode. Their pH is usually between 2-5 .
Anionic emulsion:
If an electric potential exists between two electrodes immersed in an emulsion containing bitumen negatively charged particles, they migrate towards the anode. The pH of these emulsions is usually between It is 9-11.
Emulsion failure
After spreading the bitumen and contacting the materials, the water is separated from the bitumen and a film of bitumen remains on the aggregates. Ambient temperature
- humidity
- absorption capacity of materials
- wind speed
- time interval between execution and opening of traffic
