The Use of Polymer Materials in the Composition of Asphalt Concrete
Abstract. The research presented in the article shows the possibility of using some polymer materials in the composition of asphalt concrete. The analysis of scientific works in the field of asphalt concrete design shows the efficiency of using plastic waste to obtain asphalt concrete with specified physical, mechanical and operational properties. This technology allows not only to reduce the amount of accumulated plastic waste, but also to improve the condition of highways by increasing the strength of asphalt concrete. Polymers PP and LDPE were selected for the study. As PP samples, we used a nonwoven material used for the production of disposable medical masks, which is suitable for creating linear or dispersed reinforcement of asphalt concrete. LDPE was used as the second polymer sample. The obtained asphalt concrete samples differ from the traditional composition by their increased compressive strength at high temperatures while maintaining plasticity at low temperatures.
