NOISE ABSORPTION STRUCTURE APPLIED IN A RAILWAY

摘要

A sound absorption structure to reduce noise forming a soundproof member installed between both rails of a railway, in the outer sides of both rails of the railway, or a roadbed of the railway is formed into a flat plate shape by mixing a binder wherein a main material and a hardening agent is mixed at a weight ratio of 60:40-40:60 of the aggregate. The sound absorption structure to reduce noise comprises 1-10 parts by weight of the binder with respect to 100 parts by weight of the aggregate. The thickness of the sound absorption structure to reduce noise is 25-200 mm. The purpose of the present invention is to provide the sound absorption structure to reduce noise emitted when a railway vehicle drives with excellent sound absorption capacity, excellent durability, and high economic efficiency.
