The effect of the structure-forming modifying additive Plastobit based on synthetic waxes for the physical and mechanical properties of bitumen and asphalt concrete

The purpose of this work is to study the changes in the physico-mechanical characteristics of organic binders modified with additives based on synthetic waxes, their effect on polydisperse organomineral compositions (asphalt concrete). National projects such as "Safe, high-quality roads" and "Creating a comfortable urban environment" are aimed at bringing transport and operational characteristics up to standard, restoring and improving public roads and the road network, as well as the largest urban agglomerations. The use of a modifying additive will allow them to extend the interrepair time of the highway and reduce the development of plastic deformations. Using well-known methods and modern scientific and technical laboratory equipment, comparative tests were carried out, which made it possible to identify patterns of change in the physical and operational characteristics of fine organomineral compositions. Based on the studies carried out and the laboratory results obtained, recommendations for the use of a modifying additive were formulated and given, which was reflected in practical application at the facilities of reconstruction and repair of highways during the installation of the upper layers of coatings.
