• Abstract:
  In the summer of 2008 two CKD stabilization test sections were constructed on the I-75/I-96 Gateway roadway
  
  reconstruction project in Detroit near the Ambassador Bridge.
  
  Through observation and testing, CKD adequately stabilized both subgrade test sections. One test section
  
  consisted of a predominantly silty clay soil and the other had a mixture of sand over silty clay. Dynamic Cone
  
  Penetrometer (DCP) test results showed a substantial increase in subgrade soil strength through CKD
  
  stabilization. On average CKD stabilized areas showed an 885% strength gain though stabilization relative to
  
  the existing soil strength. Lime stabilized areas showed an average increase of 531%.
  
  Based on the test sections it was concluded that CKD has advantages and disadvantages in comparison to Lime
  
  stabilization. CKD stabilization did result in higher and quicker soil strength gain which could accelerate
  
  construction activities. Also, incorporation has environmental benefit since this “by-product” material has
  
  historically been disposed of in a landfill. However, CKD material has more risk in that it is less predictable in
  
  nature because it is a ‘by-product”. The material is finer which poses more dusting concerns. And there are
  
  tighter construction restrictions due to early set time.
  
  Also of concern, previous laboratory work done by others has shown mixed results in long term strength loss of
  
  CKD treated soils if it becomes saturated due to capillary rise of ground water. A long term performance
  
  monitoring program is in place for the two test sections and Lime stabilized areas to observe strength changes
  
  through time.
