Road pavements are an integral part of modern infrastructure, playing a crucial role in ensuring the efficiency of automotive transport, enhancing road safety, and promoting economic development. In any country, road pavements must be of high quality and durability, as their lifespan, operating conditions, and maintenance costs largely depend on the materials used, particularly the composition of concrete. The demand for concrete materials is also increasing, as they are one of the most widely used construction materials. The growing need to enhance the quality of concrete and enrich it with environmentally friendly materials, along with the necessity to address global challenges such as climate change and resource depletion, makes the improvement of concrete composition for road pavements a pressing issue. European countries have established a number of important standards for developing road infrastructure. These standards are primarily designed to ensure the quality of road pavements, enhance safety, and improve the efficiency of vehicles. As part of the European Union, many countries have implemented common rules and standards for road pavements and concrete materials. These standards aim to ensure the strength of pavements, their long-term 105 SCIENCE AND INNOVATION IN THE EDUCATION SYSTEM International scientific-online conference performance, and their environmental cleanliness. The innovative technologies used in the concrete production process in European countries, as well as architectural and engineering styles, create unique characteristics for road pavements adapted to local conditions. The main objective of this article is to develop an optimal concrete composition for road pavements and study European practices. Throughout the article, modern trends, innovative approaches, and challenges in the production of road pavements in Europe will be analyzed. To achieve this objective, the following tasks have been set: Analyzing the types of concrete used for road pavements in European countries.Investigating the process of developing optimal concrete compositions. Identifying the possibilities for adapting European standards and technologies to local conditions. Considering the ecological aspects of concrete and examining the use of innovative materials. Studying the types of concrete used for road pavements and their characteristics is essential for constructing effective and long-lasting road structures. Various types of concrete developed in European countries, such as plain concrete, reinforced concrete, Portland concrete, and special concretes, differ in their technical and economic properties. In this context, the analysis of the strength, durability, and other mechanical properties of each type of concrete will provide the necessary knowledge to improve the concrete composition used in local conditions. The process of developing an optimal concrete composition is complex and depends on many factors. Within this task, particular attention will be given to the criteria for determining the composition, such as the operating conditions of the product, strength, stability, and economic aspects. Through practical examples and experimental research, optimal results can be achieved by combining various materials and aggregates. The process of developing optimal composition will be expanded with new approaches aimed at enhancing the durability of concrete and considering ecological aspects. The standards currently implemented for the production and use of road pavements in European countries are of significant importance for their application in local conditions. Within this task, studying European standards and comparing them with local conditions is necessary to find the most effective solutions and implement new technologies. Through innovative approaches that 106 SCIENCE AND INNOVATION IN THE EDUCATION SYSTEM International scientific-online conference are suited to local conditions, the quality of road pavements can be improved, and efficient resource utilization can be ensured. Today, it is essential to consider ecological aspects in concrete production. This task involves examining the po
