Making bitumen emulsions
Today, two methods for preparing bitumen emulsions are common in road construction, which are:
1- Continuous method
2- Modular method
The main difference between these two methods is that in the preparation of bitumen emulsion by continuous method, bitumen phase and aqueous phase are instantly prepared and injected into the production system. If in the modular method, the aqueous phase is prepared separately in two modules or the bitumen phase is mixed instantly in a colloidal mill. In the bitumen emulsion production process, the emulsion solution and bitumen are passed through the mill to make the emulsion. The pumps introduce the emulsion solution of bitumen into the mill. Emulsion solution consists of water, emulsion, acid and, if necessary, stabilizer, which are mixed carefully and in appropriate proportions to obtain a uniform solution with the desired degree of acidity. The bitumen used can be pure bitumen or bitumen mixed with an oil solvent such as kerosene or diesel or vegetable oils. The emulsion is removed from the hot mill. Therefore, before transferring to the storage tank, it must be entered into heat exchangers to reach the appropriate temperature and then enter the storage tank.
The emulsion temperature during manufacture should never exceed 100 ° C and should be kept between 85 and 95 ° C. In order to avoid local temperature rise, the temperature difference between the bitumen and the emulsion solution should be as small as possible. The bitumen must be hot enough to be pumped. For emulsions with 60% bitumen, the set temperature of the two phases should be considered around 195 ° C and the temperature of the emulsion at the outlet of the mill should be around 90 ° C. Before producing bitumen emulsion, a suitable formula should be selected to make it according to the application and related properties and relevant standards.
