RECYTRACK is a 3.5 year project granted by the European Union through LIFE+ 2010 program. The overall objective of the project is to demonstrate the environmental benefits and technical and economic feasibility of the implementation of an elastomeric eco-friendly material made of end-of-life tires with resin for railway applications. Within the consortium, AV Ingenieros jointly with LEAM, carries out the study of the vibration behavior of the eco-friendly material, which will be applied as a mat for ballasted tracks as well as an isolated block system for slab tracks. Firstly, an analytical model capable to characterize the eco-friendly material vibration behavior is under development. Subsequently, and after the implementation of the eco-friendly solutions in real railway infrastructures, its vibration behavior will be measured and validated through in situ measurements during the infrastructure commercial exploitation.
