EVALUATION OF RECYCLED AGGREGATES & FLY ASH USED IN FLEXIBLE PAVEMENTS: A MODEL STUDY

Ggregates are used majorly in the formation of road which is formed by crushing natural rock. Studies show that there are several alternate materials which can be used for replacement. Recycled aggregates from removed road sections, construction and demolition wastes are one of those alternatives. Generally this wastes end up in landfill creating a major environmental challenge to be solved. With emerging trends in technology various innovative ways can be created which are prudent and ecofriendly. The present paper aims in varying the strengths of flexible pavements in which recycled aggregates are used as partial replacement of natural aggregates. Marshall's stability test is used to study the strength variations.
