Bitumen is typically mixed with aggregates (like sand and gravel) to form asphalt concrete, which is used for paving roads. The process involves: 1. Heating: Bitumen is heated to a liquid state (150−180 °C) to reduce its viscosity. 2. Mixing: The hot liquid bitumen is then thoroughly mixed with heated aggregates in a specialized asphalt mixing plant. This ensures each aggregate particle is coated with a uniform layer of bitumen. 3. Compaction: The resulting hot mix asphalt is transported to the site and laid in layers, then compacted using rollers to achieve a dense, durable surface.

Solved: How is bitumen mixed | Chemistry

The process involves:

Heating: Bitumen is heated to a liquid state ( $150-180 \text{ }^\circ\text{C}$ ) to reduce its viscosity.
Mixing: The hot liquid bitumen is then thoroughly mixed with heated aggregates in a specialized asphalt mixing plant. This ensures each aggregate particle is coated with a uniform layer of bitumen.
Compaction: The resulting hot mix asphalt is transported to the site and laid in layers, then compacted using rollers to achieve a dense, durable surface.
