Rubber phenyl will be used on single-track railway crossings – the first set of the five phenyls mentioned above was used in Tbilisi at the railway crossing of the Tbilisi junction -Ponichala. This will reduce the impact caused by the movement of railway and road vehicles, minimize the noise level and increase the carrying capacity of vehicles at the crossing. The embossed surface of phenyl creates an anti-slip effect, which is important from the point of view of traffic safety.
