Horizon 2020 SME 2° grant 738373: “GREENRAIL”

IPOOL S.r.l. carried out the vibro-acoustic characterization of railway sleepers made of rubber powders deriving from ELTs (End-of-Life Tires) and evaluation of noise and vibration reduction induced to the receiver by the railway infrastructure or by train passages.
Project funded by the European Community for GREENRAIL, ECOPNEUS and Milan Polytechnic.
