Abstract

The need for sustainable and cost-effective materials for road construction has led to better
attention in the use of agricultural waste products for soil stabilization. This review examines
the geotechnical properties of lateritic soil modified with Rice Husk Ash (RHA), focusing on its
appropriateness for road applications. It discusses the effects of RHA on key soil properties like
compaction characteristics, Atterberg limits, California Bearing Ratio (CBR), Unconfined
Compressive Strength (UCS), and permeability. The review findings from various studies
indicate that RHA significantly improves the strength and stability of lateritic soils, making it a
promising stabilizing agent in pavement construction.
