The article provides an overview of modern research aimed at improving the durability of concrete pavements of highways through the use of mineral additives and modifying components. The results of field and laboratory tests of high-volume fly ash concretes (HVFA), mixes with ground granulated blast furnace slag (GGBS), silica fume, and composites reinforced with polypropylene fibers are reviewed. Analysis of international studies shows that replacing 30-80% of Portland cement with additives significantly reduces permeability, increases frost, sulfate and corrosion resistance, and decreases the carbon footprint of concrete pavements. It is noted that combining HVFA with polymer fibers additionally enhances crack resistance and ensures stable performance characteristics. Based on the generalized data, it is demonstrated that the use of modified cement concretes is a promising direction for improving pavement durability under aggressive environmental conditions and significant temperature fluctuations.
