What is a typical formulation for asphalt concrete?

The formulation for asphalt concrete typically consists of a combination of aggregates, asphalt binder, and additives. Aggregates make up the bulk of the asphalt concrete and can include various sizes and types of materials such as gravel, crushed stone, and sand, which provide structure and strength. The asphalt binder, which is a petroleum product, acts as a binding agent that holds the aggregates together and provides durability. Additives may also be included to enhance specific properties of the asphalt concrete, such as improving its performance in extreme temperatures or increasing resistance to moisture.

This formulation is crucial for ensuring the pavement can withstand traffic loads, weather conditions, and other environmental factors over time. The correct answer reflects the standard composition used in the construction and maintenance of roads and highways.
