Base Stabilization is used in new construction and reconstruction to improve the physical and load bearing properties of an aggregate base layer. In areas of low supply of quality aggregates, Base Stabilization can reduce material needs, conserving natural resources and reduce costs. Base Stabilization is similar to Full Depth Reclamation with the major difference being that Base Stabilization deals with aggregate layers where FDR incorporates bituminous layers with underlying granular materials. 

  1. 20% to 40% Cost Savings
  2. 20-60% Reduction in Trucking of Materials
  3. 100% Reuse of Material on In-place Projects
  4. Same day return to light traffic for In-place Projects
  5. Up to 25 years of life extension. The limiting factor for service life of base stabilized pavements is typically the service life of the surface course and not the stabilized mixture itself.
  6. Structural Layer (a) Coefficients of base stabilized layers depends on the stabilizing agent used and vary from 0.15-0.25 for cementitious stabilization to 0.20-0.30 for bituminous stabilization.

Issues Addressed

  • Limited availability of quality aggregates  
  • Expensive aggregate costs 
  • Inadequate structural integrity
  • When performed in-place can address the same issues as FDR


  • Reduces base layer thickness by increasing the structural integrity of the base
  • Can reduce base layer and/or concrete or asphalt surface thickness
  • Enhances existing aggregate properties
  • Reduces trucking
  • When performed on existing pavements, it has the same attributes as FDR
