Abstract
Taking account of the fact that there is complex space load on the carriageway of the South highway stream crossing it is reasonable to use numerical method for determination of stain and tension pavement condition based on the solution of elasticity theory equations – Finite Element. The application of numerical modeling is determined by the fact that load patterns are becoming more complicated and require spacial concept in order to enhance the quality of overpass pavement design. Atypical example for deformation fields distribution in one of the bridge crossing sections under traffic load is provided. The analysis of the investigation results enables us to conclude that the minimum tension stress in the pavement will be at the pavement thickness 90 mm and stamp diameter 300 mm. under this condition the tension in the pavement will not exceed 3.7 MPa.
