CURRENT STATE OF METHODS FOR DETERMINING THE ADHESIVE AND COHESIVE PROPERTIES OF ROAD BITUMEN

Abstract

The sphere of transport infrastructure is developing rapidly, which underlines the importance of stable properties of bitumen in the construction of road surfaces. A necessary condition for improving the quality of the bitumen binder is its high adhesionto the surface of the mineral filler. The adhesion of bitumen with mineral filler is an important indicator that characterizes the quality of the asphalt concrete mixture, the performance characteristics of the asphalt concrete coating and its resistance to damage. An adequate assessment of these characteristics becomes a key factor in ensuring the durability and reliability of road surfaces. The article analyzes the current state of methods for determining the adhesive and cohesive characteristics of bitumen and mineral filler. The aimof the work is a thorough analysis of various methods used to evaluate the adhesive and cohesive properties of bitumen, with subsequent identification of their advantages and disadvantages. An overview of both traditional and modern approaches used to determine these characteristics is given to better understand the structure and behavior of bituminous materials. Conclusion. The article emphasizes the need for further research and development in the field of methods for determining the adhesive and cohesive properties of bitumen, considering modern requirements for road infrastructure. It is necessary to develop scientific and practical approaches to improving existing regulatory documents considering the characteristics of bituminous materials.It can be concluded that it is necessary to develop new accurate reproducible methods using computer technologies that automate data collection and processing and reduce the likelihood of errors.
