  • Asphalt layers subjected to distress due to weather and excessive application of repetitive loads which results in failure causes the fatigue and rutting. Hot mix asphalt (HMA) layer should be prepared with new materials such that durability of pavement increases and shall withstand the excessive application of repetitive load. The use of nanomaterials shall provide solution in an effective process for improving performance characteristics. In the present study nanosilica was prepared and modified with bitumen binder to understand the performance characteristics. The nano structure was synthesized with microscopic observation. Rheological properties of modified binder when investigated and observed that inclusion of silica has increased the visco-elastic properties of the binder which provides better fatigue and rutting properties. The mixes prepared with modified bitumen exhibited better resistant for rutting and moisture sustainability.
