Effects Of Aging Condition, Preconditioned Temperature And Anti-Stripping Agent On The Adhesive And Cohesive Behaviour Of Asphalt Binder And Mastics

Warm Mix Asphalt (WMA) has gain wide acceptance by asphalt industry especially in the United States due to its ability to lower asphalt mixing and compaction temperatures by 20°C to 55°C compared to the conventional Hot Mix Asphalt (HMA). This characteristic makes WMA a greener technology as less em...
