Crushed Aggregate Stone: Unveiling the Basics. At its core, crushed aggregate stone refers to a versatile construction material derived from crushing large rocks, boulders or gravel. The process involves breaking down these raw materials into smaller, uniform pieces, resulting in aggregates with varying sizes and textures.
Aggregates are the most basic material used in construction. They provide the foundation for roads, bridges, and buildings, while also making up more than 90 percent of an asphalt pavement and up to 80 percent of a concrete mix. On average, 38,000 tons of aggregates are necessary to construct one lane mile of interstate highway.

2.1.2 Fine Aggregates. The material passing the 5 mm No. 4 sieve is known as fine aggregate. Fine aggregate consists of screenings, sand, soil, or other finely divided mineral matter that is processed or naturally combined with the coarse aggregate. 2.1.3 Gradation Requirements.
They use high-speed impacts to make materials even smaller and more even in size. This gives you control over how your crushed materials turn out. A jaw crusher is a sturdy machine that breaks down big rocks and ores into smaller pieces. It has two main parts: a fixed jaw that doesn't move and a swinging jaw that does.
