Abstract:

The article addresses the challenges and methodologies for enhancing the properties of asphalt concrete utilized in the Republic of Armenia. Environmental factors, including abrupt temperature fluctuations, precipitation, and black ice, coupled with the escalating load on road surfaces, necessitate the development of high-performance asphalt concrete. To this end, both local mineral resources and various industrial waste materials have been investigated for their potential to augment the properties of bitumen. It has been determined that the most effective additive-modifiers are synthesized from waste materials, specifically aluminum palmitate and aluminum oleate. These additives enhance bitumen properties and are likely to fortify the chemisorption bonds at the interface between bitumen and the mineral phase. The study further examined the variation in bitumen properties based on the type and quantity of synthesized additive-modifiers incorporated. Results indicate that the most substantial improvement in modified bitumen is achieved at a concentration of 3 mass percent of the additives relative to the weight of the bitumen.
