Use of asphalt cracks as filling in geotechnical applications

In our increasingly crowded world, the consumption of natural resources such as water, oil, minerals and forests is increasing rapidly and these resources are rapidly depleting. The asphalt compound used in road construction, maintenance and repair is a very expensive material produced from natural resources, but it is also an extremely valuable and usable material in the form of asphalt crumb after it is excavated from the roads. In this context, the use of asphalt crushed asphalt as a filler in geotechnical applications should be a common task of all sector representatives, legislators and public institutions in order to protect natural resources, prevent environmental pollution and save the economy. Materials such as asphalt crumb can be recycled and reused by appropriate physical and chemical processes. This process protects natural resources while also ensuring that materials of economic value are brought back into the economy. In this study, the recyclability of asphalt crushed asphalt obtained from IBB was investigated for use as backfill material in geotechnical applications. Experiments have been conducted and examples from field applications are given. In order for the recycling system to be established in Turkey, necessary infrastructure works and legal regulations should be made as in Europe, and entrepreneurs should be supported to the necessary extent. In this way, a sustainable recycling system can be established and a significant contribution can be made to the protection of natural resources. RAP material can be used as backfill material in some applications, but it is important that the applications should be accompanied by laboratory tests and field quality control tests.
