Performance of rubber bituminous asphalt mixes at hot and warm production temperatures.

In the production of asphalt mixtures, the possibility of recycling rubber grits has appeared for decades. A rubber bituminous mixture appearing as a special Hungarian patent greatly reduced the viscosity problems of rubber bitumen mixtures, resulting in a bitumen type that is easily transportable and does not require special equipment, The asphalt mechanical properties of the MOL rubber bituminous mixture are excellent both in the field of plastic deformation, cold behavior, and fatigue properties, so they are real competitors to polymer-modified bituminous mixtures. New research possibilities have emerged for use at reduced production temperatures, as a so-called WMA asphalt mix, in which case the first experimental – wheel tracking and cold behavior test - results are also encouraging.
