ABSTRACT
Moisture damage of flexible pavements hinders construction of durable pavements. Siliceous aggregates are found to aggravate the damage. Hydrated Lime (HL) fillers provide resistance to such damage. In this study, purely siliceous aggregates were considered, and the increment of resistance to moisture damage was studied using nano hydrated lime (NHL). NHL was synthesized using planetary ball milling. A comparative study was carried out on the improvement of moisture damage resistance using both HL and NHL particles. It was observed that although mix fails for unmodified mixes, addition of HL and NHL particles reduce the moisture susceptibility and results in development of moisture resistance mixes. Mix prepared with 1% addition of NHL showed best results in terms of resisting moisture damage.
