What are aggregates? Aggregates are raw materials that are produced from natural sources and extracted from pits and quarries, including gravel, crushed stone, and sand. When used with a binding medium, like water, cement, and asphalt, they are used to form compound materials, such as asphalt concrete and Portland cement concrete.
The energy required to extract, produce, and refine paving materials is a huge contributor to the energy required for road construction, whether they are constructed using asphalt or concrete. As a result, the embodied energy of each material tells us a lot about the total requirements of road construction.
