- Abstract
A method of estimating the stress-strain state of road pavements resulting from the effect of operating loads was developed. For solving the above mentioned problem, mathematical models of deformation, which are based on solving the classical Boussinesq problem, were used. The formulae for calculating six components of a tensor of mechanical stresses in road pavements for estimating the depths at which stresses have maximum values were studied. A scheme of traffic loads during the active road transport movement for different number of vehicles was proposed. Based on this scheme the formulae for determining all components of the stress tensor were suggested. For implementing the developed models and algorithms, the software systems were created. In addition, the model and practical computations for real road sections with different types of pavement were carried out. The possibility of considering the peculiarities of spatial configuration of highway sections and, in particular, their curvature radii while estimating the stress-strain state of these sections, was studied. This approach will allow working out software systems for estimating and predicting the road pavements state, based on the traffic analysis and studying physical and mechanical properties of the materials, which the pavements were made of. The further coordinates for studying the problem were defined.
