Study of deformation properties of road foundations of the mixed type intended for the movement of mobile complexes for monitoring and transporting raw materials

Analysis of the conditions of movement of mobile robotic complexes showed that about 70% of the time of movement is made up of sand, gravel and sandy areas. In winter, it is covered with snow. An unsolved problem is the traffic conditions during the transition period, namely, movement on snow-sandy...
