Aggregate base course is an engineered mixture of coarse and fine aggregate designed to support heavy loads and is used in many applications such as foundations for highways and buildings as well as support of equipment on unpaved surfaces such as job site roads and oil well pads. Coarse.

Gradation and Size Pavement Interactive

The particle size distribution, or gradation, of an aggregate is one of the most influential aggregate characteristics in determining how it will perform as a pavement material. In HMA, gradation helps determine almost every important property including stiffness, stability, durability, permeability, workability, fatigue resistance, frictional resistance and moisture susceptibility (Roberts et ...

Choosing Decorative Aggregate The Concrete Network

Aggregate size and shape vary, too. The size, which can range anywhere from 3/8 inch to 2 inches or more in diameter, largely determines the depth of exposure. Aggregate shape affects the surface pattern and texture. Rounded aggregates provide the best coverage and a smoother surface while angular aggregates add more texture and dimension.
