How to Perform Base Stabilization - AsphaltPro Magazine

The depth at which you are stabilizing will determine the size of roller required. Typically, base stabilization ranges from 6 to 14 inches. “Our stabilizers will mix up to 24 inches deep, but you can only process how deep you can compact,” White said. “Most contractors’ rollers can compact around 10 to 12 inches.”.
