Abstract

a promising direction in solving the problem of obtaining high-quality asphalt concrete is the use of mineral fillers, including from industrial waste. The article considers the use of OEMK slag as a mineral powder in the asphalt concrete mix. The influence of hydrophobization of mineral powder by GF Preparation on moisture absorption and its structuring ability to change the maximum shear stress from the content of mineral powder before and after hydrophobization was studied. It is established that the treatment of the filler provides the necessary hydrophobicity of the mineral material, reduces the bituminous capacity, water saturation, porosity of the asphalt binder, and increases its strength and water resistance. The results of studies of the main characteristics of asphalt concrete on the example of a mixture of type G III of the brand showed that as a result of hydrophobization, the strength, water resistance, water saturation, and swelling of the composite significantly increase
