Description
Summary:AbstractConsumption of resources is increasing as the world’s population and industrialization rise, so that natural resources are being exhausted. Therefore, the use of waste and recycled materials is very important to achieve environmental and economic benefits. This study assessed the effects of compaction energy and the role of a binder on the properties of two control groups (A and B) of hot-mix asphalt used for surface layers, prepared according to European Standards. Group A consisted of stone dust, subfractional glass, and a binder. Group B comprised stone dust, subfractional stone aggregate, and a binder. Laboratory testing determined the effect of the observed variables on the density of asphalt samples and ratio of air voids and voids filled with bitumen. The findings indicate that the compaction energy and glass fraction in the asphalt mixture had a significant influence.
