Bitumen Emulsion

Product Details

Emulsified Bitumen usually consists of bitumen droplets suspended in water. This dispersion under normal circumstances would not take place, also everyone knows, oil and water don’t mix, but if an emulsifying agent added to water asphalt will remain dispersed. Most emulsions used for surface treatments. That`s enable using lower temperatures (45°C-70°C). This is much lower than 150-190°C used for hot mix asphalt cements. The lower application temperatures will not damage asphalt and are much safer for field personnel. In bitumen emulsion production, water treated with emulsifying agent and other chemicals. It pumped to colloid mill along with bitumen. The colloid mill breaks bitumen up to tiny droplets. Emulsifying agent migrates to asphalt-water interface and keeps droplets from coalescing. Emulsion then pumped to storage tank.
