Here are four of the more common types of construction aggregates. Gravel. In 2023, we used 120,000,000 metric tons of gravel in the United States alone. Gravel is created when stones are eroded over long periods in water or through sedimentation. These processes break them into smaller pieces naturally over time.
These aggregates are mixed with water and a binder to create a wet mix, which is then compacted and laid as a base layer during road construction. Generally, the aggregates used in WMM should be hard, durable, and resistant to weathering to provide a stable and long-lasting base for the road. Aggregate . Physical Requirements:
