This eLearning lesson on permanent deformation was first produced as a special output for the ROADEX III project in 2008 and has been subsequently updated to its present condition by the ROADEX Network.

The lesson draws heavily on experiences gained over the course of the ROADEX projects and subsequently with work carried out by the ROADEX Network. The goal for the lesson is to provide ROADEX state-of-the=art knowledge in such a fashion that it can be quickly used by road engineers in their day-to-day work in road condition management.

The main production team for the lesson has been Dr Timo Saarenketo of Roadscanners Oy, the primary author of the work, and Mr Mika Pyhähuhta, of Laboratorio Uleaborg, who was responsible for the artistic design and production. Co-authors have included Prof. Pauli Kolisoja for the Tampere Technical University, Dr Andrew Dawson from The University of Nottingham, Mr Ron Munro from Munroconsult , and Mrs Annele Matintupa and Mr Petri Varin from Roadscanners Oy.

The eLearning team wishes to thank all of the people involved with the production, particularly the ROADEX Network Steering committee for their encouragement and enthusiasm in the project.
