SYNTHESIS OF MODIFIERS FROM PETROCHEMICAL WASTE FOR ASPHALT CONCRETE MIXTURES

Abstract

In this work the synthesize of organic amine-derived surfactant from petrochemical waste are considered, which will be used as a modifying additive for improved performance properties of asphalt concrete coatings. The relevance of this study is determined by the problem of solutions in the field of secondary processing of various waste products of petrochemical production for the purpose of their subsequent application for the synthesis of a new product. Recycled materials can be successfully used for the road construction industry as part of asphalt concrete coatings. This approach will significantly reduce the level of environmental pollution, and is also beneficial from an economic point of view.Using the method of probabilistic-deterministic planning of the experiment the modes of obtaining various compositions of amine derivatives by the reaction of amination of higher aldehydes with gaseous ammonia in the presence of lower aldehydes are optimized. The synthesis products are recommended for use as modifiers for the development of asphalt concrete mixtures with improved structural and mechanical characteristics. Due to the introduction of the synthesized AC-1 modifier at the level of 0.1-0.2%, the structural and mechanical characteristics of asphalt concrete mixtures are improved, which allows the use of this cost-effective modifier in the production of road surfaces with improved performance properties.
