1. Why Aggregate Shape MattersAggregate shape is one of the most critical factors determining the performance of concrete and asphalt mixtures. Cubical particles pack tightly within the mix matrix, maximizing inter-particle contact area and friction, which directly translates to higher compressive strength and improved structural stability. Conversely, flaky or elongated particles (those with a length-to-thickness ratio exceeding 3:1) create a bridging structure within the mix, increasing void c...
