Abstract—
A model is developed to identify the main factors and analyze their influence on normal displacements of a roadway surface under the action of a moving load. The model takes into account a multilayer road structure and rheological properties of the ground. The upper layers of asphalt concrete are modeled as a relatively rigid layer, the disconnected layers between the asphalt concrete and the ground are modeled by a base with a Winkler layer, and the soil is considered a viscoelastic half-space. The influence of the sliding velocity, interlayer adhesion, and rheological properties of the ground on surface deformation is analyzed. The effect of reducing maximal surface displacements with increasing sliding velocity is obtained. The developed computational program is designed for use in interpreting measurements of road surface displacements with equipment that provides the surface with a uniform load moving at a constant velocity.
