A Study on Moisture Susceptibility of Foamed Bitumen Mix

With the growing concern on global warming, there is a constant demand for technologies which can help reduce emissions. One such technology is warm mix asphalt (WMA) which reduces the mixing and compaction temperatures of the pavement materials leading to less energy consumption, fewer emissions, better workability, and reduced aging. One of the WMA techniques is foaming of bitumen which ...
