3.7.3 Particle Shape

The particle shape of material will affect compaction as particles tend to pack more efficiently when better shaped. Long, thin particles may fracture during placement and compaction and also affect the workability of the material, making it difficult to achieve satisfactory compacted density. Some micaceous fines components may meet normal grading requirements but, because of their plate-like and flake-like shape and elastic properties, interfere with the compaction process.
