Abstract:-The use of alternative materials in geotechnical applications is gaining attention due
to environmental and economic concerns. One such material, Recycled Concrete Aggregate
(RCA), has emerged as a potential substitute for natural aggregates in earth dam filters. RCA,
derived from demolished concrete structures, offers sustainable benefits by reducing construction
waste and minimizing the extraction of virgin aggregates. This study investigates the feasibility of
using RCA as a filter material in earth dams by evaluating its permeability, grain size distribution,
hydraulic performance, and long term durability. A key concern in using RCA for filtration is its
ability to meet conventional filter design criteria, including adequate permeability and particle
stability to prevent clogging or excessive migration of fines. Laboratory testing and field trials
have been conducted to compare RCA’s performance with traditional aggregates in terms of
gradation, porosity, and durability under different hydraulic conditions. Results indicate that well
processed RCA can exhibit comparable or even superior filtration properties, making it a viable
alternative for sustainable dam construction.
