Summary

The project, described in this paper, has its origins in one of the major problems faced by the railways at this moment: ballast deterioration. The high maintenance cost that this represents for railways, combined with the difficulty of obtaining high-quality aggregates and the problems generated by the vibration induced by train passage, evinces the need of an improved ballast. The project NEOBALLAST, which aims to provide a solution to the existing problems by using a new material is described here. The method of project validation consists of three phases of trials that are distinguished by its typology. The first two stages are developed in the laboratory and correspond to: the testing of isolated particles and the characterization of the ballast as a whole. The last stage consists of a field test, simultaneously with an informatic model. The results obtained in stage one have been very positive and we are currently developing the second phase of trials. Thus, if the positive results continue as is expected, the impact of this project will be of great importance to maintenance operations, noise and vibrations.
