        abstract = {The increasing traffic intensity and axle loads on rigid pavements necessitate high-performance concrete with improved fatigue resistance and durability. Conventional pavement concrete is often vulnerable to cracking and surface deterioration under repeated wheel loading. This study investigates the flexural fatigue performance of nano-silica modified concrete for rigid pavement applications. Concrete mixes incorporating varying percentages of nano-silica (0%, 1%, 2%, and 3%) were prepared along with supplementary cementitious materials. The experimental program included compressive strength testing, full-scale wheel load fatigue testing, Falling Weight Deflectometer (FWD) analysis, Load Transfer Efficiency (LTE) evaluation, abrasion resistance, and impact resistance tests. Results indicate significant improvement in strength, stiffness, fatigue life, and durability with nano-silica incorporation. The optimum performance was observed at 2% nano-silica content. Enhanced microstructure due to the nano-filler effect and pozzolanic reaction contributed to improved crack resistance and reduced deflection. The study confirms nano-engineered concrete as a promising material for durable and sustainable rigid pavements.},
