particles using the packing volume concept developed by Tons and Goetz [24]. They found a significant increase in asphalt mix stability with increasing geometric irregularities of the aggregate particles [23]. 4. Conclusions The present study was undertaken to investigate the effect of fractal dimension on mechanical properties of asphalt concrete. The test results indicated that there is a strong correlation between fractal dimension of coarse aggregates and mechanical properties of asphalt concrete. Hence, it may be said that the fractal dimension of aggregates is used for determination of mechanical properties of asphalt concrete. References 1. Kuo CY, Frost JD, Lai JS, Wang LB.
