The pond ash (class F) as an individual material is unsuitable for utilization in pavement constructions due to few undesirable physico-mechanical properties. Treatment of pond ash by suitable additives like cement and lime would improve its usability. The present study is intended to determine the strength and stiffness properties such as Unconfined Compressive Strength (UCS), California Bearing Ratio (CBR) and Resilient modulus (M R ) of both untreated and lime-treated pond ash for its

... t subbase application. The experimental investigation illustrates the enhancement in UCS, CBR, and M R properties of lime-treated pond ash compared to untreated/virgin pond ash specimens. Further, a significant improvement was observed at lime content about 8%, which can be considered as optimum addition to pond ash for pavement constructions.
