• Description:
  The concept and feasibility of stockpiling and reusing hydrated lime-soil mixtures to stabilize particular areas on stabilization projects after the mixing contractor has departed were examined. In chemical stabilization of subgrades, situations often arise where additional areas need to be stabilized after the specialty contractor and mixing equipment have left the project. Field and laboratory investigations were performed to determine if a soil mixed with hydrated lime during routine lime subgrade stabilization could be mixed, stockpiled, and used later. In laboratory studies, hydrated lime-soil mixtures were stockpiled loosely in the laboratory. CBR specimens of the stockpile material were remolded and soaked at selected times. Values of CBR increased with increasing times. Those studies storngly indicated that hydrated soil-mixtures could be stockpile and reused.
