ALIZE-LCPC® — Pavement Design Software

ALIZE-LCPC® — Pavement Design Software

Developed by Université Gustave Eiffel, in collaboration with STAC for the aeronautical module. Distributed by itech-soft since 2003.

Overview

Alizé2® is a pavement structure design software based on the French design method and compliant with the standard for new pavement structure design NF P98-086. It relies on the calculation of stresses and strains in a Burmister model. The structure consists of a stack of horizontally semi-infinite layers resting on a semi-infinite half-space. Material behaviour is assumed to be linearly elastic.

ALIZE-LCPC®, Alizé-Aéronautique® and Alizé2® are registered trademarks. The software is registered with the Agence pour la Protection des Programmes.
