Abstract
The article is devoted to modeling the asphalt-concrete layers stress-strain state of flexible pavement. For most of the materials used in the technique, plastic deformations only depend of the acting forces values and of their application order, but not on the duration of the action and not on the speed which the load is applied. Asphalt concrete, as thermoplastic composite material is in a different position. In asphalt-concrete materials operating conditions when temperatures elevated, the relationship between forces and displacements is significantly time-dependent. Therefore, a task is set about determining the internal forces (stresses), deformations (displacements for points) of arbitrary shape body with its arbitrary load.
