In the context of several solutions that can be used to improve the performance of asphalt mixtures during their service life, the paper presents a case study in which asphalt mixtures are manufactured using some recycled materials such as glass, plastic and rubber. The level of performance will be quantified both by the rheological properties measured by conventional tests (viscosity, permanent deformation etc.), but also by some tests that take into account the change in response over time and that lead to variation curves for the stiffness modulus, yielding and fatigue resistance etc. Asphalt mixtures with different percentages of recycled materials will be studied and the results obtained from dynamic and rheological tests before and after the aging process will be compared and interpreted. Determining the degree of influence of recycled materials on the aging resistance of modified asphalt mixtures and characterizing the dynamic and rheological properties can lead to optimizing the percentages of additions and choosing the most advantageous solution based on multi-criteria analyses in different climatic and stress conditions.
