The article presents a new mathematical model that describes the soil ground with plenty of discrete obstacles. Analysis of roughness allowed to identify the main types: the wave, triangle, cylinder, pock. We analyzed specific types of roads with plenty of threshold obstacles, namely: forest roads, broken asphalt road, «stone-road». As a result of measurements roughness distributions versus their length were obtained. It is concluded that exponential distribution law is the most appropriate for the mathematical modeling. First time new mathematical relationships to determine the dependences of the distribution of characteristic roughness were shown. These dependencies allow to use the data to predict the vibrational loading of vehicle in conditions of the ground of this type. The limitations are conditions of the smooth running and geometric mobility of vehicle.
