👉UNDERSTANDING ROAD LAYERS
💫Every strong and durable road you drive on rests on a powerful structure beneath, not just asphalt!
🏷Here’s the breakdown
1. Pavement (Surface Layer):
This is the visible top layer made of asphalt or concrete providing a smooth, safe, and waterproof surface for vehicles.
2. Base Course:
The load distributor! It transfers traffic loads from the surface to the lower layers. Usually made of crushed stones or gravel.
3. Sub-base:
Acts as a cushion and improves drainage. It reduces stress on the subgrade and prevents pumping of fine materials.
4. Subgrade:
The foundation of the entire pavement system made up of compacted natural soil. Its strength and stability determine the performance of the whole road.

what about the capping course
