Moisture Damage of Bituminous Pavements and Application of Nanotechnology in Its Prevention

Chakravarty, Hillol / Sinha, Sanjeev

This review paper gives a brief overview of moisture damage and the materials used to prevent it. It has been observed that bituminous mixes suffer from durability issues such as moisture damage and oxidation. Even the usage of conventional antistripping materials such as lime and liquid antistripping agents (LAS) are not able to prevent the moisture damage completely. The studies supporting the effect of particle sizes of additives on the moisture resistance of bituminous mixes was the motivation behind the investigation of the use of nanomaterials for this global problem. The scope of this review is to understand the mechanism of moisture damage and the use of nanotechnology for its prevention. This study is an effort to look into the recent use of some nanomaterials in bituminous mixes for the development of mixes with better durability against moisture-induced damages. This review also focuses on the important nanocharacterization tools that are employed to understand the moisture damage of bituminous mixes at the nanoscale.
