Aggregate is essential to our daily lives. Every Californian uses over 22,000 pounds of aggregate each and every year. Over 2 billion tons of aggregate is used annually to build our roads, bridges and other essential infrastructure.
It takes 15,000 tons of aggregate required to build a school or hospital. Over 38,000 tons of aggregate is used in 1 mile of four lane highway. 90% of aggregate is used within 90 miles of its place of extraction.
