USE OF INNOVATIVE TECHNOLOGIES IN THE CONSTRUCTION OF ROAD PAVEMENTS

Abstract

Problem statement. Ukraine, on its way to European integration, faces the challenge not only of joining the European Union, but also of adapting its infrastructure to high European quality standards. After the end of the war, it is necessary not only to rebuild the destroyed roads, aerodromes and buildings, but also to guarantee the sustainability and durability of infrastructure facilities. One of the key industries where innovations can make a significant difference is road construction. Asphalt and concrete are the most common building materials in the construction of flexible and rigid pavements. Innovative technologies for repairing cracks in asphalt and concrete road pavements are constantly evolving. New methods and materials are being sought for more efficient and long-term maintenance of the road surface. The use of advanced technologies allows us to improve the quality of repairs, extend the service life of roads and reduce their environmental impact. Innovative approaches to crack repair help to ensure safety and comfort on the road for all road users. The purpose of the article is to analyze foreign experience in the application of effective innovative technologies in the construction of road pavements and to substantiate the feasibility of using a self-healing top layer of flexible and rigid asphalt and concrete pavements in Ukraine based on the analysis of their properties. Conclusions. The inclusion of self-healing properties in asphalt concrete pavements is an effective method for increasing their service life and achieving environmental friendliness of pavements. Existing and advanced self-healing technologies suitable for use in asphalt pavements, namely, the inclusion of healing agents, induction heating, and hybrid technologies, have been investigated. The mechanisms of self-healing of concrete have been studied: autogenous, based on autonomous bacteria, and based on autonomous capsules. Research on self-healing pavements is aimed at developing a smart and efficient pavement system capable of self-assessment and automated crack repair. The choice of technology should be based on its ability to effectively repair damage and cracks in asphalt and concrete, providing long-term and reliable protection.
