Reduced Moisture SusceptibilityUnstabilized Granular BaseHigh water tableFull Depth Reclamation BaseMoisture infiltrates base:• Through high water table• Through capillary action• Causes softening, lower strength, andreduced modulusFull Depth Reclamation:• Reduces permeability• Helps keep moisture out• Maintains high level of strength andstiffness even when saturated
Reduced Fatigue CrackingAsphaltSurfaceUnstabilized BaseHigh deflection due tolow base stiffnessResults in high surface strainsand eventual fatigue crackingFull Depth Reclamation BaseHigher stiffness offull depth reclaimedbase produces lowerdeflectionsResulting in lowersurface strains andlonger pavement life
