Definitions
- the present invention relates to formulations, and in particular formulations based on surfactants, useful in particular for the preparation of bitumen emulsions, and more specifically to the preparation of bitumen emulsions for severe-emulsions.
- the present invention also relates to the bitumen emulsions prepared with said formulations, as well as their implementations for the preparation of serious-emulsions and other types of emulsions.
- bituminous emulsions The market for surfactants for bitumen emulsions is today constantly growing, and especially for the market of serious-emulsions. These additives are of particular importance for this type of bituminous emulsions in that they play an important role not only in the stability of the bitumen emulsions but also in the robustness of the bituminous mixes prepared from said emulsions.
- US 3859227 discloses slow-breaking cationic bituminous formulations comprising at least one alkylphenol alkoxylated.
- alkoxylated alkylphenols are strictly controlled, these products being considered today as possibly posing risks to human health.
- US Pat. No. 6,840,991 shows that lignosulphonates are not the most suitable for the preparation of stable bituminous emulsions; indeed, the formulations presented based on lignosulphonates have only relatively poor granule coating characteristics.
