• Abstract:
  Due to rising costs of good quality acceptable materials for remove/replace options and traditional ; subgrade stabilization materials, MDOT is in need to identify potential recycled materials to treat ; unacceptable subgrade soils. Use of recycled materials may not only provide less costly ; alternatives for subgrade stabilization, their use may also alleviate landfill disposal challenges. ; This research study is aimed at identifying short-term and long-term advantages and ; disadvantages associated with subgrade stabilization using recycled materials such as Cement ; Kiln Dust (CKD), Lime Kiln Dust (LKD), flyash, concrete fines and mixtures of LKD and FA. An ; extensive laboratory testing program was conducted to determine suitability of the above recycled ; stabilizers for subgrade stabilization for common problematic soils found in Michigan. The ; laboratory investigative program involved determining the basic soil properties, developing mix ; designs to select proper stabilizer percentage for each soil type, CBR testing to determine ; pavement design parameters, and laboratory freeze/thaw testing to determine durability of ; stabilized subgrade sections. A limited field investigation was performed to assess insitu ; performance of stabilized subgrades. Based on the findings of both investigations, stabilizers ; were selected for long-term subgrade stabilization for different soil types and their associated ; pavement design inputs were determined. A design matrix with cost considerations was also ; developed to aid the selection of subgrade treatment options.
