Emulsion Bitumen Supplier
Bitumen Emulsion consists of three basic ingredients: bitumen, water, and an emulsifying agent. Based on specifications it may contain other additives, such as stabilizers, coating improvers, anti-strips, or break control agents. It is well known that water and asphalt will not mix, except under carefully controlled conditions using highly specialized equipment and chemical additives.
Anionic and Cationic emulsifiers are all available, which will successfully emulsify bitumen and provide storage stable emulsions. Cationic emulsifiers offer additional advantages, which arise from the fact that most naturally occurring aggregates are negatively-charged in aqueous media, and have a capacity to absorb Cationic Emulsifiers. Choice of emulsifier type, and emulsion formulation enables the rate of breaking of the Emulsion to be controlled. The emulsifiers remain in the cured seal and are concentrated at the interface between bitumen and aggregate and act as antis tripping agents.
