This paper presents an assessment of newly-developed conductive adhesion materials (Products A-D) in comparison to standard rail sand used in Britain. The particles were characterised to assess their densities, and size and shape distributions. Bulk behaviour was assessed through three characteristics: angle of repose, bulk shear strength, and particle breakage index. Materials were then assessed using a high pressure torsion approach to measure their effects on adhesion and electrical resistance in dry, wet, and leaf contaminated conditions. It was resolved that all products produced better conductivity than GB rail sand and Product D should be considered for future field testing.
