This paper brings an original contribution in the analysis of stray current and the evaluation of maximum potential in reference to particular transportation service conditions. Beginning with a real new transit system under construction in Italy, a finite element method analysis has been developed in order to propose precautionary measures to prevent the growth of anodic areas in reinforcement bars and to influence the design procedure for better environmental compatibility. A possible solution to respect the limits imposed by the international standards is presented. Real infield measurements with the aim to validate the data implemented in the model complete the study.

Abstract
This paper brings an original contribution in the analysis of stray current and the evaluation of maximum potential in reference to particular transportation service conditions. Beginning with a real new transit system under construction in Italy, a finite element method analysis has been developed in order to propose precautionary measures to prevent the growth of anodic areas in reinforcement bars and to influence the design procedure for better environmental compatibility. A possible solution to respect the limits imposed by the international standards is presented. Real infield measurements with the aim to validate the data implemented in the model complete the study.| File | Dimensione | Formato | |
