Enhancement of road pavement material using conventional and nano-crude oil fly ash

 · The percentage of conventional and nano-ash used in asphalt mixes was varied from 0 to 15% of asphalt binder. The use of nano-fly ash increases the rutting factor by 0%, 33%, 61% and 38% at 0%, 5%, 10% and 15% nano-fly ash content, respectively. The nano-fly ash improves the rutting factors and bearing load capacity of flexible pavement mixes ...
