Dubyk O. Simulation of stress-strain state of non-rigid pavements restored on cold recycling technology

Object - regularities of the deformation of pavement layers of flexible type, reduced cold recycling technology; purpose - to determine the stress-strain state of non-rigid pavements restored cold recycling technology based application load space character from the action of super heavy vehicles; methods - finite element method; Analytical method of calculation; prediction residual strain in the layers of non rigid pavements structures; induction and deduction; novelty - improved existing approach to study stress-strain state of non-rigid pavements on the basis of relations torque finite element schemes; improved modeling process stress-strain state non rigid pavements physically and geometrically nonlinear formulation; improved algorithm and a package of automated programs to calculate stresses, displacements and strain in structural elements of non rigid pavements; results - developed software by creating automated calculation section pavements; conducted advanced numerical experiment and analysis of stress-strain state restored non rigid pavements for the two sections of roads; industry - construction
