IMPACT OF DEFECTS AND DESTRUCTION ON THE CHANGE IN THE BEARING CAPACITY AND DURABILITY OF RIGID PAVEMENT STRUCTURES

Igor Gameliak Anna Kharchenko Andrii Dmytrychenko

Various theoretical models and formulas are considered, in particular the Winkler-Zimmermann hypothesis and the Westergaard method, for calculating the stresses and deflections of slabs under loading in the center, at the edge and at the corner. The main type of failure of rigid road pavements is the chipping of the corners of the slabs, which is often observed in concrete without reinforcement. The analysis shows that the most dangerous location of the load is at the corner of the slab, where the stresses are 1.8 times greater than in the center
