Road Treatment: Reconstruction
A reconstruction project consists of:
1. Removal of existing road surface
2. Reconstructing or rehabilitating the road bed
The road bed is the layer below the road surface. It can be reconstructed with similar material or it can be rehabilitated by pulverizing and mixing cement into the existing structural section to a depth of approximately 1 foot. Replacing or rehabilitating the road bed increases the structural capacity of the road section to a level that is required for long term performance.
3. Placement of new road surface
The new road surface is typically 2 inches of asphalt concrete placed on top of the road bed.
