Nanotechnology has been gradually penetrated into the field of asphalt modification. Seemingly magic effects of nanomaterial have been brought to improve the performance of asphalt. Pavement failure is characterized by many factors of failures. Any improvement in service life of road pavements will be off course of a great economical advantage and any modifications of asphalt are attempts to extend the service life and improve the performance of asphalt pavements This paper investigates the feasibility of using Nano silica particles to enhance the physical properties of asphalt binder. Properties of bitumen mixes change with time of ageing which starts from bitumen manufacturing temperature which leads to distress of the pavement with ever changing climate. This study aims to improve the understanding effect of bitumen on short term ageing on its properties. In order to resist the ageing process, the modifier Nano-silica the particles are added in suitable doses and the engineering properties are scientifically evaluated in the laboratory checked for its effectiveness.
