Experimental assessment of recycled asphalt-bonded materials

Abstract

In general, nature needs to be protected. For that reason, waste and landfills should be prevented. In order to minimize these negative effects on the environment, it is necessary to use recycled materials. Hence, the paper's objective is focused on material recycling which presents a suitable form of material reusing. During recycling, materials that have already been used are incorporated into new constructions. Constructional waste is generated during the production of certain materials and the erection stage. Besides, it is undesirable and difficult to dispose of. Moreover, it creates a financial cost that burdens and affects individual construction processes and, finally, creates a negative impact on the environment. Therefore, recycling plays an important role in waste disposal. Material reuse is the process by which material is employed for construction without any modification. The benefit of recycled material usage lies in efficient material processing, economic savings, simplification of technological procedures, and reduction of the carbon footprint. During recycling, some properties of the asphalt material are modified. One of the most affected is the fraction because of the aggregate crush. It is an experimental assessment of recycled asphalt mixtures materials and their comparison with materials that do not contain recycling. The article compares the different properties of mixtures with and without R-material. It defines the influence of the presence of R-material on the properties of asphalt mixtures.
