Aggregates are often overlooked when we talk about the construction industry today. There not appealing or any fun to look at.

That said, aggregates are – quite literally – the building blocks of our society. Aggregate production dates back to the Roman Empire, and it has been critical to the growth of our world ever since.

Aggregates are the most basic material used in construction. They provide the foundation for roads, bridges, and buildings, while also making up over 90% of an asphalt pavement and up to 80% of a concrete mix. On average, 38,000 tons of aggregates are necessary to construct one lane mile of highway. Construction of the average home requires 400 tons of aggregate, while the average size school or hospital requires 15,000 tons.

That’s a huge impact for some 'rocks'.
