Ecological asphalt mixtures

This article presents experimental results obtained on road materials and their improvement from the use of non-biodegradable waste, such as polystyrene and tire rubber. A dense hot mix was analyzed, which is of great use in flexible pavements. A chemical and rheological analysis of the modified binders with non-biodegradable waste was performed. In this phase of research the asphalt mixture’s response to effects such as rutting, fatigue and the alteration of the dynamic modulus was proved depending on the modifier used. For the analysis of the studied mixture, the aggregates, the asphalt and the modifiers were characterized. The trials were conducted for chemical stability, deformation, fatigue and dynamic modulus. Finally, the obtained results were analyzed and the benefit, the improvement and proper utilization of the investigated mixture are presented. The scope of this phase of the research is to observe this new material’s response for asphalt mixtures.
