Abstract. The essence of soil moisture stabilization technology lies in the introduction of reagents that bind moisture, chemically or physically remove excess moisture from the soil during compaction, thereby ensuring an optimal moisture regime for road structures. This allows for subsequent soil stabilization using mineral binders if necessary. This study addresses the task of extending the duration of action of dust suppression and soil moisture stabilization materials through the application of multifunctional surfactants. The results of successful field trials using dry chloride mixtures with surfactants on low-traffic roads are reported. The effectiveness of dust suppression and soil moisture stabilization materials through the use of multifunctional surfactants has been confirmed. Soil samples stabilized with such salt mixtures containing water-soluble amines remain intact.

Experimental implementation of dust suppression materials based on magnesium chloride hexahydrate and anhydrous calcium chloride with an amine-group surfactant was conducted on road sections in the Moscow and Volgograd regions. As a continuation of this work, it is advisable to investigate the potential use of these materials as corrosion inhibitors, antioxidants, and anti-caking agents.
