FIELD: construction.
SUBSTANCE: invention relates to road construction and can be used for dust control of roads and airfields with crushed stone, gravel and sand, and ground paving. The method of treatment of dusting surfaces includes the surface treatment with aqueous solution of calcium chloride. Before the calcium chloride treatment the surface dusting material is pre-mixed to the depth 3.5 cm with the natural zeolite having a particle size 0.5-5 mm and a consumption rate 1.2-1.5 kg / m2. Then, the surface is moistened with water, held within 24-30 hours and treated with 25-40% aqueous solution of calcium chloride.
EFFECT: increase of the period of de-dusting action due to increasing the water retention capacity of the coating and reducing the salt elution.
