CHEMICAL STABILZATION • Mixing or injecting additives: • Two types Standard stabilizers : lime, Cement, sodium silicate, calcium chloride, bituminous materials and resinous materials. Non standard stabilizers: Sulfonated Oils, Ammonium Chloride, Enzymes, Mineral Pitches and Acrylic Polymers.
Selection of stabilizer • Selecting the stabilizer type depends on number of factors including: • 1. gradation, • 2. plasticity index (PI), • 3. Availability and cost of the stabilizer and appropriate construction equipment • 4. Its long term effect on strength etc.
