• Abstract:
  The Wisconsin Department of Transportation (WisDOT) spends approximately 10 percent of
  
  its improvement project budget on embankment construction each year. A critical aspect of
  
  embankment construction is stability. It is needed to provide an acceptable foundation for
  
  pavement construction and will contribute to the long-term performance of the pavement structure.
  
  To achieve this, WisDOT developed specifications for embankment density and has developed
  
  specifications to limit the thickness of embankment lifts placed during construction. The current
  
  specifications limit lift thickness to 0.20 meters (8 inches) for most soil conditions. However, if granular
  
  soils are used and density measurements are being made, a 0.30-meter (12-inch) lift thickness may be
  
  allowed. The 8-inch lift limit is by far the most common application on departmental projects. The
  
  0.20-meter (8-inch) lift limit has been the standard for WisDOT construction for many years. This limit
  
  was based on practical field experience with contractor methods and equipment. It has been accepted as
  
  a reasonable soil thickness that would contribute to adequate embankment compaction without excessive
  
  testing and inspection by WisDOT staff.
