Soil Stabilization benefits

  • Stabilization increases the sheer strength value of soils, thus adding support.
  • Stabilization helps to control shrink-swell properties associated with many soils, thereby improving the load-bearing capacity of sub-grade intended to support pavement sections, building pads etc.
  • Additional benefits include lower permeability, higher resistance values and potential reduction in base and pavement thickness due to the strength gains achieved by stabilizing the subgrade.
  • Lime and cement modification can cut costs and save time on project schedules by reducing soil drying time or eliminating the need for costly unsuitable material removal and replacement.

    Soil Stabilization process

  • A specially designed reclaiming machine pulverizes the existing subgrade surface to a pre-determined depth providing a homogeneous mixture.
  • An additive (Portland Cement, Lime, LKD, Fly ash) is then spread across the pulverized surface.
  • The additive is blended with the subgrade material until the desired properties are achieved. (Water addition rates may require adjustments throughout the project due to material variability)
  • The new base is shaped by a motor grader to the proper profile and compacted to the specified dry density as determined in the previously completed mix design. (In-place density testing performed by a field technician during the compaction process verifies proper compaction.)
