Rut (roads) - Wikipedia

A rut is a depression or groove worn into a road or path by the travel of wheels or skis. Ruts can be formed by wear, as from studded snow tires common in cold climate areas, or they can form through the deformation of the asphalt pavement or subbase material. The main reason is heavy loaded truck acts more pressure than assumed during the construction of roads.
