This project rebuilt and recycled the existing road surface using a process called Stabilized Full Depth Reclamation (SFDR).

How it works

  1. Break it down: Machines grind up the old asphalt and some of the gravel underneath.
  2. Strengthen it: Special materials like cement or asphalt emulsion are mixed in to make the recycled base stronger.
  3. Pack it tight: The new mix is compacted to form a solid, durable foundation for the road.
  4. Resurface: A new layer of asphalt is paved over the surface.

Benefits

This process saves money, protects the environment by reducing waste and truck traffic, and creates stronger, more durable roads by reusing the existing surface.
