A cost-effective, long-lasting greener alternative to deep rehabilitation or removal and replacement techniques. Full Depth Reclamation (FDR) is an engineered rehabilitation technique in which the full thickness of the asphalt pavement and a predetermined portion of the underlying materials (base, subbase and/or subgrade) is uniformly pulverized and blended to provide an upgraded, homogeneous material. The reclaimed materials may be improved and strengthened by using Mechanical, Chemical or Bituminous stabilization. FDR isn't only for roads in poor condition, it is also a viable design process for increasing the structural capacity of a pavement in good condition.
40 to 80% less expensive than alternative reconstruction techniques
Importing and exporting of materials can be reduced by 90%
Reuses up to 100% of existing materials
Same day return to light traffic
Up to 25 years of life extension. The limiting factor for service life of FDR treated pavements is typically the service life of the surface course and not the FDR mixture itself.
Structural Layer (a) Coefficients of FDR mixtures depends on the stabilizing agent used and vary from 0.14 for pulverization and mechanical stabilization to 0.15-0.25 for cementitious stabilization to 0.20-0.30 for bituminous stabilization.
All forms of cracking and rutting
Reduced ride quality due to pavement distress
Loss of surface integrity due to raveling, potholes and bleeding
Excessive shoulder drop off
Inadequate structural capacity
Eliminates all existing surface distresses
Stabilization turns a deficient pavement structure into a new homogeneous section with increased structural capacity
Reduces impact on underground utilities and structures
Conserves non-renewable resources and reduces trucking
Deteriorated subgrade or base can be reshaped to restore surface profile and drainage
Cost savings compared to other rehabilitation methods
Reduces community impacts, traffic disruptions and user inconvenience
Reduces contractor change orders resulting from unstable soil/base conditions
