ABSTRACT:
This specification discloses method and apparatus for treating surface layers of the earth to obtain stabilization, build strength and permeability characteristics; characterized by slaking quicklime (CaO) in a mixing tank to form an elevated temperature, hydrated lime [Ca(OH).sub.2 ] slurry and working the resulting elevated temperature lime slurry into the surface of the earth at the local where the stabilization of the soil is to be achieved. This achieves a cost reduction, has greater reliability in obtaining materials, achieves better results, saves energy and extends the soil-stabilization season into cold weather previously considered prohibitive. Also disclosed are the details of preferred embodiments for admixing the unslaked lime.
