Analysis of the Pavement Response with Total/Partial Link Between Layers to the Action of Traffic Load

Abstract

AbstractThe paper investigates the response of the pavement of a road sector analyzed to the traffic load that was determined numerically by using Abaqus numerical modelling software. This tool offers advanced analysis options in comparison with the normative road structure dimensioning tool. Thus, in contrast to the current use road structure dimensioning program, the FEM software allows the definition of the interfaces between layers and switch loads from static load to moving load, based on the determination of the resilient stresses and deformations in road structures by using the classical linear elastic multilayer model. The aim of this study was to determine whether the road pavement with deficiencies of adhesion between asphalt layers can take over the calculated traffic load considered in the study, or the proportion of design traffic load that can be taken over. That would allow an assessment of the service operation life of the road pavement and, implicitly, of the possibility of its yielding before the end of the perspective period considered.
