The next phase of the research will involve evaluating the deformed state of the restored pipes through injection technology under the influence of dynamic loads. 5. Conclusions The static experimental tests on pipes, where the load-bearing capacity and integrity were restored using a two component epoxy material through injection, led to the following conclusions: 1. The maximum vertical deformations of the rehabilitated pipe at the onset of crack formation were 4.83 mm at the top, 4.92 mm at the bottom, and 2.69 mm at the side. Subsequently, at the moment of pipe destruction, the maximum vertical deformations reached 7.05 mm and 8.09 mm, with horizontal deformations measuring 7.68 mm. 2. The utilization of crack injection technology with two-component epoxy materials proves effective in restoring the integrity and load-bearing capacity of concrete pipes. As such, this technology can be reliably applied to pipes already in operation. References Bęben Damian, 2013. Evaluation of backfill corrosivity around steel road culverts.
