How It Works – FDR with Cement / Stabilizers
“Now we use the Zipper and do full-depth reclamation (FDR) with a cement and lime mixture. Water is added with a water truck and it is all mixed together with a grader. After compaction the street is left to cure for a couple of days. Finally sealcoat is applied as the wearing course. This isn’t just a surface treatment, it’s full-depth and we saved 48% of what it would have cost to do a surface treatment. I expect these new streets will last at least 10-15 years.”

Chemical Stabilization with Cement, Lime, Fly Ash, etc.
Pulverize asphalt with a predetermined portion of the base.
Apply stabilizer to the surface of the pulverized roadbed.
Thoroughly mix stabilizer into the road base. Water can be injected through onboard sprayer.
Additional water can be added.
Grade and reshape the crown of the road.
Compact, compact, compact with sufficient moisture. When cured it can be paved or sealed.
