If the aggregates are flat and/or elongated, they can fracture, thus creating a void in the mix. Cubical-shaped products lock together better as a skeleton within the matrix, providing a better-performing mat under compaction, while reducing voids in the mix. The cubical shape is a better product for both bituminous asphaltic concrete and ...

Abstract. It is well known and taken for granted that the efficiency of energy use by comminution (i.e. breaking, crushing, grinding) equipment is very low, typically less than 10%. Most of the process input power is dissipated as heat and noise and ineffective deformation of the material to be processed and the device itself.
