FULL DEPTH RECLAMATION
REUSE EXISTING MATERIAL
CORRECT SUBGRADE DEFICIENCIES
LKD (lime kiln dust)
CKD (cement kiln dust)
Full Depth Reclamation (FDR) is a rehabilitation process that rebuilds worn out asphalt pavement by blending existing roadway materials with a stabilizing additive. The existing asphalt and aggregate base materials are first blended with a predetermined portion of the underlying subbase, then water is added to achieve optimal moisture content for compaction. A stabilizing additive appropriate to existing conditions is applied at a rate according to an engineered mix design. The materials are mixed to form a homogeneous base. After shaping and grading the new base is compacted to produce a strong, durable base ready for pavement.
Chip Road (from 7 Mile Rd. to 8 Mile Rd.)
Bay County, MI
Faced with tight budgets and a network of roads in dire need of repair, Bay County Road Commission officials were looking for efficient, economical treatement of aging roads damaged by heavy truck and farm equipment traffic they were not designed to handle. Working on a mile stretch of county road Wadel Stabilization performed full-depth reclamation with cement stabilization to produce a new 12" stabilized base. With minimal disruption to area residents, in just a days time WSI left a mile stretch of road graded, compacted, and ready for a chip seal wearing course. FDR allowed existing roadway materials to be reused, eliminating the need to remove old roadway materials and avoiding the cost of purchasing, hauling, and placing new materials. Soil stabilization using Portland cement applied at 3% provided a new base with increased structural capacity and moisture resistance.
