ViscoRoute©
ViscoRoute© — Pavement calculation under moving loads
Software for calculating displacement, stress and strain fields in bituminous pavement structures under moving loads, developed at LCPC in 2003 in partnership with ENPC. The online GUI (v3) is maintained by the MAST-LAMES team at Université Gustave Eiffel.
Overview
ViscoRoute© calculates displacement, stress and strain fields in pavement structures that are infinite in the horizontal plane and in depth. The load(s) move along the positive X axis at a non-zero, assumed constant speed. The contact pressure (vertical or otherwise) can be uniformly distributed over a point, rectangular or elliptical surface.
Layer behaviour is either elastic or thermo-viscoelastic. In the latter case, the Huet-Sayegh model parameters (1963 & 1965) are used for bituminous mixtures. These are obtained by fitting master curves from laboratory tests using the ViscoAnalyse software.
Interfaces between layers are either perfectly bonded (version 2.1) or perfectly sliding (version 2.2). The calculation kernel has been registered with the Agence pour la Protection des Programmes since 2009.
Features
Moving loads at constant speed
Realistic simulation of traffic load passages (heavy vehicles, trams, aircraft) taking into account the speed of movement.
Viscoelastic behaviour
Thermo-viscoelastic modelling of bituminous mixtures using the Huet-Sayegh model, for a faithful representation of real material behaviour.
Multi-layer — Bonded or sliding interfaces
Different interface conditions between layers: perfectly bonded (v2.1) or perfectly sliding (v2.2).
Varied contact surfaces
Contact pressure can be applied over a point, rectangular or elliptical surface, with the option to include non-vertical components.
Online GUI — Version 3 (2024)
Web interface for creating input files, running calculations, visualising and saving results directly from a browser.
APP registered since 2009
The calculation kernel and its updates are protected by registration with the Agence pour la Protection des Programmes, ensuring version traceability.
History
2003
Created at LCPC in partnership with ENPC
