The Benefits of Cubical Aggregate AsphaltPro Magazine ...

During crushing and screening, cubical-shaped aggregate particles are created, along with so-called flat or elongated shaped particles, and fines. Since the advent of Superpave mixes in the late 1990s, mix designs have limited the percentage of flat or elongated particles allowed in a mix.

Effect of crusher operation on coarse aggregate shape A

For crushed aggregate, cubical or nearly cubical particles are preferred. As the number of flat and elongated particles increases, concrete workability decreases and water needed to achieve a given slump increases. Coarse aggregate shape also af-fects concrete strength through a complex relationship of aggregate-to-cement-paste bonding properties.
