8.2.4 Shape of aggregates Aggregates which happen to fall in a particular size range may have rounded, cubical, angular, flaky or elongated particles. It is evident that the flaky and elongated particles will have less strength and durability when compared with cubical, angular or rounded particles of the same aggregate.

VSI Crushers: Vertical Shaft Impactor (VSI) crushers use a high-speed anvil rotor that accelerates the aggregate and crushes it into cubic shapes. They are popular for producing good aggregates in good shape. Function and operation: Aggregate crushers are designed to handle huge rocks extracted from quarries or demolition sites.

Therefore, aggregate shape is one of the important properties that must be considered in the mix design of asphalt pavements to avoid premature pavement failure. The shape of aggregate particle has a significant influence on the performance of the bituminous pavement. Particle shape can be described as cubical, flat, elongated and round.
