👉Flexible Pavement Layers

💫Surface Course (Asphalt): Top layer that provides a smooth riding surface and protects the pavement from traffic and weather.

💫Base Course: Strong aggregate layer that distributes vehicle loads to lower layers.

💫Subbase: Intermediate layer that improves drainage and provides additional support.

💫Subgrade: Natural soil foundation that supports the entire pavement structure.

🚧Together, these layers ensure strength, stability, and durability of the road.

👉Flexible Pavement Layer System

1. Subgrade (Soil) – Natural ground that supports the entire pavement structure.

2. Geotextile Fabric – Separates soil and aggregates, improving stability and drainage.

3. Granular Sub-Base – Distributes loads and prevents excessive settlement.

4. Aggregate Base Course – Provides structural strength and load-bearing capacity.

5. Hot Mix Asphalt Binder Course – Intermediate asphalt layer that adds strength.

6. Hot Mix Asphalt Surface Course – Top riding surface, ensuring smoothness, safety, and durability.

Together, these layers distribute traffic loads safely to the underlying soil and increase pavement life.
