The usability of bayburt trass with recycled asphalt pavement in bituminous hot mixtures

The general view in today's world is to use existing resources more efficiently and effectively. The rapid increase in the number of motor vehicles and the development of new roads and / or the deterioration of the existing roads constitute an important place in this sense, but it is very important to reduce the material consumption and costs. This has led to the need to recycle waste materials or the materials previously used. In this study, a new bituminous hot mixture was obtained by laying together the Bayburt trass as a waste material and the asphalt mixture obtained by excavating from a road surface that has completed its service life and obtained as a wear layer on an active highway. Core samples were taken from the coated wear layer for one year. Marshall stability and flow, indirect tensile strength, indirect tensile elastic modulus and dynamic creep tests were performed on the samples. From the test results, it has been determined that the materials can be used in bituminous hot mixtures.
