Efficiency of Restoration of Cement Concrete Pavements Using Wearing Courses

The paper presents the results of research on the efficiency of restoring the performance characteristics of cement concrete pavements using wearing courses. International and national experience in the application of thin and ultra-thin layers is analyzed. The effectiveness of technologies such as microsurfacing, slurry seal, and thin asphalt layers is evaluated. The economic and operational advantages of preventive maintenance are substantiated. In 2025–2026, a test of cold high-crushed asphalt concrete Road Pave was conducted in the Kyiv region. The mixture was laid in a layer of 15 mm at an air temperature of +10°C on a wet concrete surface. After two weeks of operation, the condition of the site was assessed as excellent, no crushed stone was recorded. This confirms the possibility of using cold technologies for the operational protection of concrete slabs. The main efficiency factors: technical condition of the surface; traffic intensity; climatic conditions; quality of materials and technology of work. The economic efficiency of using wearing layers consists in reducing costs by 35–45%; postponing major repairs from 2–4 to 10–15 years; increasing the efficiency of using limited resources. The scientific novelty lies in the established dependence of the efficiency of wearing layers on: the condition of the surface; type of technology; composition of the mixture. The feasibility of using micro-covers as an optimal solution for cement concrete surfaces is substantiated. The practical significance of the results obtained lies in the use used in the development of regulatory documents; in the practice of operating highways and in planning repair measures in the SUSP or HDM system. The most promising direction for Ukraine is the development of cold mix compositions with increased adhesion, clarification of DSTU requirements for surface treatments, diluted bitumen, cold asphalt concrete mixtures, preventive maintenance of CСP and training of qualified personnel of road workers capable of meeting the level of modern technologies
