FIELD: building, particularly to consolidate motor road bed, paving or slopes. ^ SUBSTANCE: method involves serially treating ground with 20% aqueous saponified tall pitch mixed with waste oil from motor car engines at t=50-100°C up to emulsion obtaining and with 10% aqueous calcium chloride solution; leaving ground as it is to provide full polymerization and compacting ground under pressure of not less than 15.0 MPa. Ratio between saponified tall pitch and waste oil is 1.0:0.01-0.1. Ratio between above emulsion and aqueous calcium chloride solution is 1:0.28-0.3. The invention is disclosed in independent claims. ^ EFFECT: increased strength and frost-resistance of consolidated ground. ^ 8 cl, 1 ex, 5 tbl |
