The article presents results of research on the possibility of reduction of technological temperatures of highly modified binders by using as an additive a fluxing agent of plant origin, developed at the Warsaw University of Technology. The work presents the results of dynamic viscosity tests within the temperature range of 90°C to 180°C for original binders and binders aged using the RTFOT method, modified by adding a fluxing agent of plant origin. On the basis of dynamic viscosity test results, process temperatures for production and compaction of mineral-asphalt mixes with the binding agents being analyzed. Moreover, characteristics of binders were assessed, which define their behavior under high technological temperatures on the basis of multiple stress creep recovery (MSCR) tests. The research results obtained indicate that it is possible to reduce the process temperatures of mineral-asphalt mixes with highly modified binders by liquefying the binder with an additive of plant origin while retaining high resistance to permanent deformations. The MSCR test results prove that mineral-asphalt mixes containing binders highly modified with additives of plant origin can meet the requirements for extremely high traffic loads.References
