Summary
An improvement, strength and deformation characteristics of saline loess soils are discussed in the paper. Using the results of
laboratory tests in field conditions, a recommendation has been developed on the use of stabilizers to improve the properties of
loess soils used in calculation of road pavements design. Studies have been conducted to substantiate the design characteristics of
the working layer of the subgrade built of saline soils with account of hydro-thermal regime; the development of design solutions;
the improvement of the methods for determining humidity and functional dependencies based on the determination of their
indices; the improvement of saline soils properties; the development of stabilizing surfactants “Bitumen emulsions”
Keywords: Saline soil; Stabilization; Water resistance; Bitumen emulsions; Surfactants; Loess soils; Compressive strength;
