Properties of WMA–foam mixes based on major mechanical tests

摘要: Abstract One of the main advantages warm mix asphalt (WMA) used as an alternative to conventional hot (HMA), is reduce mixing and compaction temperatures. This laboratory study was conducted with aim determining physical properties WMA mixes produced using foam bitumen technology (WMA–Foam), while applying different The effect method on also investigated. WMA–Foam were produced, adding a soft coarse aggregate particles at first stage, then hard bitumen, transformed into making device, directly added aggregates next stage. Compaction performed separately both Marshall gyratory compactors (GC) Stability void contents samples determined two major parameters for characterizing mixes. Moisture susceptibility rutting potential we...
