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

Abstract

Introduction. 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 adhesion to 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 aim of 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.
