There is a clear conscience amongst administrators and builders that investments on road network should increasingly be focused on rehabilitation (maintenance) rather than in building new roads. One of the most important matters in road rehabilitation is the pavement, in such a way that it determines its quality. Bearing in mind these facts, together with the obvious environmental and budget constraints, new rehabilitation and reconstruction techniques of road pavements with minimal resources consumption as those proposed in this project, should be considered as an opportunity and a clear option versus building of new roads.

Objectives of the Project•Be able to predict the behaviour of a pavement with FEM.• Study the influence of certain mechanic parameters both in hot-in-plant recycling techniques and cold in-situ recycling techniques.•Be able to design optimum bitumen mixtures and emulsions depending on the initial conditions.
