A new guidebook provides guidance on base stabilization methods for new construction and Stabilized Full Depth Reclamation (SFDR), and the selection of suitable nonproprietary stabilization additives for individual specific projects.
Base stabilization are techniques that amend base aggregate material, through the incorporation of a stabilizing additive, to produce a homogeneous base layer with enhanced characteristics for strength, stability, and durability. Improvements to strength and stability translate into improved performance of the supported pavement structures.
Significant improvements have been made in base stabilization practice that include design specifications and methodology, experience with the selection of stabilizing additives, and equipment for distribution and uniform blending of additives. For the rehabilitation of existing pavements, the stabilization of base material has delivered performance as good as or better than reconstruction at a reduced cost. Many additive products exist to stabilize base materials for roadway construction, but it is not always clear which additive is the right one to use.
