Abstract
- The method and equipment for determining the mechanical properties of different road bitumen were developed in KhNAHU. The method has three schemes of deformation and fracture of binders, which are located in thin layers. As a result, the following quality parameters of bitumen can be defined: the limiting tensile strength, specific energy fracture, the limiting shear strength (cohesive strength) and the glass transition temperature. The paper shows the dependence of these parameters on the change in thickness of bitumen films, the strain rate (load) and temperature. Information about the cohesive strength of asphalt with different viscosities and different structural types (“Sol” “Gel” and “Sol-Gel”) is shown here. Bitumen composition has different influence on its strength, so comparisons of cohesive binder properties with the same consistency were made. [ABSTRACT FROM AUTHOR]
