Abstract
This study focused on the consolidation characteristics of two soils stabilized with class C fly ash (CFA), lime and plastic waste. Three groups of specimens were prepared: the first group consisted of specimens prepared with 10% class C fly ash and 6% lime and then cured for 28 days; the second set of specimens was prepared with recycled plastic waste with a plastic to soil ratio (PSR) of one; and the last group consisted of specimens prepared with raw soils and compacted at near optimum moisture content and maximum dry unit weight. The last group was considered a baseline to assess the effect of CFA, lime and plastic waste on the consolidation characteristics. Results showed that CFA, lime and plastic waste stabilization reduced the compressibility of soil. In addition, both the compression index (Cc) and swelling index (Cs) decreased due to CFA, lime and plastic waste stabilization. The percentage changes in Cc and Cs varied with the type of stabilizing agents.
