Cracking is one of the main failure mechanisms of asphalt pavements. This study investigates the effects of aggregate gradation on the cracking performance of hot mix asphalt (HMA) mixtures at two stages, i.e., the cracking initiation and cracking propagation stages.
The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load. The test consists of subjecting the specimen of aggregate in standard mould to a compression test under standard load conditions (Figure 1 ).

Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.
