20.4 × 14.7 m. The pavement composition in cross -section is shown in Fig. 2. The ADINA program system is used for calculations ADINA (2017) .

Fig. 2. (a) concrete pavement composition; (b) computational model of pavement.

The Fig.2 shows the pavement layers as: CS- concrete slab, CA II.- crushed aggregate, SCI – stabilized course, PC – Portland cement and SS- subgrade soil. Vertical displacements and internal forces were investigated as an output of the calculation. Positive nomenclature for shell stress resultants is plotted in Fig. 3.
