Abstract
In order to avoid long-term waterlogging of the structural layers of the pavement and base, it is necessary to prevent the accumulation of large amounts of free water in them by installing a shallow drainage system that allows water to be quickly drained from the road structure and ensures its strength. This also necessitates the determination of the efficiency of shallow drainage structures under the influence of vehicles. The article examines the technological parameters for the arrangement of road base layers – sand layers with drainage pipes. The dynamics of the change in the area of the stamp of a pneumatic roller of different weights depending on the change in tire pressure is presented. Based on the finite element method, the stressstrain state of atypical road structures weakened by tubular drains made of materials of various origins was investigated
