Abstract: With the expansion of built-up areas, some part is alienated due to the impossibility or great complexity of construction work on it. The search for ways to strengthen weak soils is very relevant. Furfural-aniline resin (FAS) is the most studied and most often used to strengthen soils in road and airfield construction. It has hydrophobic and structure-forming properties. The manifestation of one or another property depends on the number of FAS that is introduced into the soil. When treating soils with slightly acidic and acidic reactions with small (up to 2 %) doses of FAS, the latter does not exhibit structure-forming properties, but only hydrophobizes the soil. When more than 2 % of FAS is introduced into the soil, structure-forming properties begin to manifest. The effectiveness of strengthening the soils of the FAS depends on their chemical, mineral and granulometric composition, the content of easily soluble salts, organic substances in them, as well as other factors.

Keywords: weak soils, road and airfield construction, synthetic polymers, chemical reinforcement.
