Abstract
Today, 3D construction printing is a new way to automate the manufacture of structures made of concrete and similar compounds. Wall structures are created in layers using software trajectory extrusion. This technology is widely used in civil engineering, landscape design, as well as in other areas of production where it is necessary to create complex shapes from concrete, as well as quickly create products. However, today 3D printing technology is not used in road construction, in particular, road repair and restoration work. The main purpose of this article is to consider 3D printing technology for the tasks of carrying out road repair and restoration work, as well as to compare this technology with existing methods of repairing road structures. To assess the effectiveness of 3D printing technology for road repair and restoration work, a multi-criteria analysis is used to determine the most effective technology. Based on the results of the conducted research and multi-criteria analysis, it was found that carrying out road repair and restoration work using 3D printing is an effective and profitable technology compared to traditional methods. The results obtained make it possible to use 3D construction printing for road repair and restoration work. This technology can be combined with existing pavement repair options.
