Abstract
This article presents the results of experimental studies of the influence of adhesive additives on the basic properties of modified bitumen and asphalt concrete mixtures based on it. The introduction of adhesive additives improves the basic properties of bitumen, which are necessary for obtaining high-quality asphalt concrete mixtures. Modification of bitumen increases adhesion to glass and crushed stone. Using methods of mathematical planning of experiments, experimental and statistical models of water saturation and compressive strength of asphalt concrete mixtures at temperatures of 20°C and 50°C were obtained. The introduction of modifying additives can significantly reduce the water saturation of asphalt concrete mixtures and increase strength at temperatures of 20 °C and 50 °C.
