Aggregate Gradation

Aggregate gradation refers to the distribution of particle sizes within a mixture of materials like gravel, sand, and crushed stone used in construction. It determines how well these particles are sorted across different sizes, from small to large. Proper gradation ensures the mixture compacts tightly, providing strength and stability to structures like roads and concrete. If the particles are too uniform or poorly distributed, it can lead to weaknesses or gaps, while an optimal gradation promotes durability and load-bearing capacity. Essentially, aggregate gradation is about achieving the right balance of particle sizes for optimal performance of construction materials.
