Waste Phosphate in Hot Mix Asphalts to Improve Rutting Resistance

Fillers have an important role in rutting phenomenon on highways. Investigating the rutting behavior of hot mix asphalts containing phosphate waste filler is the purpose of this research. The results compare with mixtures that contain lime stone filler (standard mixtures). The Marshall characteristics were improved for mixtures which contain waste phosphate comparing to standard mixtures. The Wheel tracking machine (WTM) results revealed that phosphate waste filler improved the rutting resistance 1.6 times as compared to the standard mixture.
