Wear resistance of high-volume fly ash concrete (HVFA) intended for pavement applications is presented in this paper. In India, the yearly production of fly ash is more than 100 million tons. The majority of fly ash is of Class F type, out of which 20-25% is being utilized in cementbased materials. In order to increase its percentage utilization, an investigation was carried out for its large scale utilization. Concrete mixes were prepared by replacing cement with 40, 50, and 60% of fly ash. Experiments were conducted for fresh concrete properties, compressive strength and wear resistance. Test results indicated that wear resistance of concrete having cement replacement up to 40% was comparable to that of normal concrete. Beyond 40% fly ash content, the concretes exhibited slightly lower resistance to wear compared to non-fly ash concretes. There is very good correlation between wear resistance and compressive strength (R2 value between 0.8482 and 0.9787 respectively) depending on age.
