Abstract

During operation, the asphalt concrete pavement is subjected to various destructive influences associated with external natural, climatic and operational factors, which can cause its premature failure. Over the past 10 years, there has been a significant increase in the fleet of vehicles in the Republic of Belarus, and, consequently, the intensity of traffic on the roads with a proportional increase in wear and destruction of their coatings. This situation is exacerbated by extended turnaround times for a number of transport facilities. The need to protect asphalt concrete pavements from the effects of external aggressive environments determines the search for new technological solutions in the creation of necessary materials, the range of which is quite wide. Existing protective compositions differ both in purpose and in the content of components. Modern research in the field of protective treatments for asphalt concrete pavements of highways, as well as technological processes used in road organizations, can effectively extend their service life. At the same time, the current research work, proven technological processes, as well as the well-known works of scientists in this field offer an insufficient number of sound technical and design solutions that allow for direct preventive protection of pavements and use for this purpose available, including secondary, materials. For more effective protection of pavements from the complex effects of water and traffic loads in the autumn-winter and spring-winter period, it is necessary to develop and implement alternative technologies, one of which is the treatment of road surfaces with the Protect-01 hydrophobic prophylactic composition. The paper presents the results of studies of the effect of treatment with the Protect-01 hydrophobic preventive composition on water saturation (decrease by 30–40 %,) frost resistance (increase by 10–12 %) and residual porosity (decrease by 12–25 %) of cores from asphalt concrete mixtures, as well as its optimal formulations.
