Milling & Stabilization Paving
The milling and stabilization process is an excellent paving method when the existing road base is poorly constructed, too thin, and/or the paved surface is in very bad condition.
Milling and stabilization is a multi-step process that requires special equipment and highly experienced staff which North American Paving can bring to the project.
The first step is to scoop the existing road pavement and base into the milling machine, seen here.
The machine grinds the material into the proper size, and discharges it back onto the roadway surface.
This a close-up of the milling machine. Note the “lid” on the scoop. It holds the material in place while the machine grinds the paving and road base into the appropriate size.
After the pavement and road base are milled to the appropriate size, the roadway must be properly graded and smoothed.
The next step is to apply Portland cement on top of the milled surface, shown above and below.
In both photos, you can see where the cement has been added by noting the color of the road surface. The portion that is a darker tan color is where the cement has been applied to the surface.
The next step is to scoop the milled material and the Portland cement back into the milling machine so that they can be thoroughly mixed.
After the the two materials are mixed, they are discharged back onto the roadway surface.
After the milled material and the Portland cement have been mixed and placed back onto the road surface, the proper amount of water must be added to the road surface.

The last step is to roll the surface to ensure that it is smooth and compacted.
The finished results --- a smooth, properly prepared surface that will provide many years of reliable use.
