What is Base Aggregate and why it is important?
Base aggregate is the crushed, well graded, aggregate layer, typically ¾" -0, placed in the construction process just prior to placing the base lift of asphalt (in thick asphalt design sections) or the final working asphalt surface in sections of 3" of asphalt or less.

Understanding Aggregate Base Course in Construction
Aggregate Base Course is typically composed of three primary materials: Aggregates; Aggregates are the key component of ABC and are usually made up of crushed stone, gravel, or sand. These materials are carefully selected to meet specific size and gradation requirements, ensuring optimal compaction and load-bearing capabilities.

The Aggregate Manufacturing Process | General Kinematics
While most people think about the construction industry when they hear the word aggregate, the truth is that nearly every product manufactured contains one or more aggregates as their base ingredient. There are even some aggregates — such as barite, bentonite, and calcite – that are valuable to the medical and health industries.
