What happens here
After the binder course has cooled sufficiently, a final layer of hot asphalt (surface course) is applied. This layer typically uses a finer aggregate mix for a smoother riding surface and is also laid using the asphalt paver. The process mirrors that of the binder layer: dump trucks feed the paver, which spreads the asphalt to the specified thickness. Workers follow behind to fine-tune edges, ensure proper transitions, and address any minor imperfections, preparing for the final compaction.
Goal: Apply the final, smooth, and durable asphalt layer
Tools and materials
- Asphalt Paver Cedarapids P385 — Spreading hot asphalt evenly to create the surface layer
- Dump Truck — Transporting hot asphalt mix to the site and feeding it into the asphalt paver
- Rakes — Manually smoothing and shaping asphalt at edges and around obstacles
- Shovels — Moving small amounts of asphalt for touch-ups
- Hot Asphalt Mix — The final layer providing a smooth and durable surface
