Materials | Free Full-Text | Effects of the Water-Based

The process of water-based foaming of bitumen produces binders that can be incorporated in cold recycled asphalt mixes and pavement upper structural layers made of half-warm mix asphalt prepared at 100-130 °C. During the foaming process, cold water and air act on hot bitumen (160-170 °C), which results in the explosive vaporization of water leading to changes in the binder structure.
