Reducing Railway Noise

Due to accelerated urbanization, industrialization and economic growth in the developed countries, rail transportation especially high-speed railways such as bullet trains have undergone a rebirth in development level and scale across these countries
There are several methods to mitigate this but some of these methods are highly expensive to build and maintain.
This brings about the introduction of porous concrete slab using Expanded Clay Aggregate (ECA®) in the construction of rail lines.
The acoustical/sound absorption properties of porous concrete materials with various gradations, aggregate types, compaction indexes, and fiber contents are determined in the laboratory.
The results show that porous concrete that uses an Expanded Clay Aggregate (ECA®) can not only bring about good acoustical absorption property but also satisfies the mechanical requirements.
The gradation of the Expanded Clay Aggregate (ECA®) has a great effect on the acoustic/sound absorption performance of the porous concrete, with high aggregate gradation of 2 - 3 mm.
The compaction index and fiber content affect both the acoustic/sound absorption and strength property of the porous concrete, with value of 0.4% and 1.8% respectively.
Porous sound-absorbing concrete slabs can immensely reduce railway noise at different train speeds and that the amount of the noise reduction changes with speed.

Benefits of using Expanded Clay Aggregate (ECA®) in the construction of Railways:

It improves stability of surrounding area and structures
It simplifies and reduces compaction
It reduces load on the supporting soil subgrade
It reduces the horizontal thrust on the supporting structures
It reduces settlement
It provides excellent insulation
It acts as an excellent drainage material
It helps reducing railway noise with porous sound-absorbing concrete slab
