Eco-materials in railway - recycling and chemical analysis

Abstract

In this paper, organic materials are studied for environmental purposes. First, recycled materials, such as anti-vibration blocks made of SBR track pads are used for reducing vibration of railway as a means to develop. It is found that low density and porous rubber blocks have suitable properties for reducing vibration and exhibit good performance. Second, an elemental analysis is carried out to evaluate environmental consciousness and development of desirable material in the future. Based on this result, desirable concepts of future materials, such as making simple components and reducing heavy metals, are proposed.
