Role of nanotechnology in bituminous road pavements

Abstract

Recently, nanotechnology is an emerging area of research in almost all branches of science and engineering. Nanotechnology deals with structure having dimension 1nm to 100 nm, plays vital role in improving the properties of the materials used for several applications. Recently nanotechnology has been effectively used in the field of bituminous road pavement treatments. The important objectives of the road pavements are to provide safe surface on which vehicle can travel easily and more safely. Pavements are mainly exposed two type of load namely travel and environment. Large number of vehicle running on the road due to their load gets affected. Similarly due to environment conditions also the road gets affected. Good pavements can be constructed using existing treatment and technique. Nanotechnology can be effectively used in bituminous road pavements towards longevity and safety of road pavements. Road pavements are of microscopic structure and nanotechnology deals with nanostructure material. In this paper we through light on the nanoscale how can affect the microscopic properties and behaviour in the bituminous road pavements.
