ВЛИЯНИЕ МОДИФИКАТОРОВ НА СВОЙСТВА АСФАЛЬТОБЕТОННЫХ СМЕСЕЙ ДЛЯ ДОРОЖНЫХ ПОКРЫТИЙ КАЗАХСТАНА

Abstract

The development of road infrastructure determines the level of economic and social development of the country. The authors' scientific approach to studying and solving the quality of road surfaces involves improving the properties of asphalt concrete by modifying the mixture. This study analyzes different types of modifiers for asphalt concrete used in the construction of road pavements in Kazakhstan. The choice of modifiers was made on the basis of an environmentally friendly solution for the production of additives based on recycled plastic, polymers and crumb rubber obtained from waste car tires. Particular attention is paid to methods for assessing the properties of modified mixtures. An analysis of the results of physical and mechanical tests of various samples with modifiers in laboratory conditions is also carried out. Conclusions about the conditions for using the considered modifiers were obtained based on the results of the study. In general, the article emphasizes the importance of using modified asphalt concrete to improve the safety and efficiency of traffic on the roads of Kazakhstan.
