USB-2V Foamed bitumen laboratory system
The USB-2-V laboratory unit is designed for production of small samples of foamed bitumen for improving the material formula.
Foamed bitumen is a mixture of air, water and bitumen. Small amount of water (about 2-3% from bitumen weight) is added to hot bitumen, resulting water evaporation, what causes foaming of bitumen in the saturated steam.
Formulas may be improved by changing of physical conditions, such as pressure and temperature.
The USB-2-V is useful as for asphalt mixing production facilities with small laboratories as for big company laboratories.
