Everything you need to know about Low Noise Concrete Pavement
Controlling traffic noise is becoming a key consideration when designing and building transportation infrastructure. The building of noise barriers or low-noise concrete pavement, with the latter being the most effective option, can reduce the noise pollution caused by vehicle movements.
Low-noise diamond grinding is the newest method in this field of noise pollution reduction, albeit there are many more.
What is Low Noise Concrete Pavement?
When designing high traffic roads, it is possible to include easily accessible diamond grinding technology to create low-noise concrete pavements. A low-noise pavement is also necessary for high traffic circumstances on important roads in order to prevent noise pollution in the surrounding area.
Concrete road surfaces may be swiftly and effectively covered with low-noise diamond grinding textures without affecting other elements like guard rails, noise barriers, or curbs.

1. Concrete road surfaces may be swiftly and effectively covered with low-noise diamond grinding textures without affecting other elements like guard rails, noise barriers, or curbs.
2. Comparing diamond grinding textures to plain concrete pavements with transverse tining, diamond grinding textures reduce road noise by almost 50%. Smoother rides and increased road safety are made possible by grinding textures.
Features of Low Noise Concrete Pavement
A road with deep negative groves on its surface is referred to as low-noise concrete pavement. These grooves, which are made with a diamond grinding machine, assist in reducing sounds brought on by heavy traffic.
Low-noise textures are created in a single pass for newly built roads, whereas the three pass process is used to repair worn-out pavements.
During the first pass, joint stepping is removed, then surface flushing is performed, and finally, grooves are cut at 12.5 mm centres during the third pass. Many roads around the world have been paved with low-noise diamond textures.
What are the merits of Low-Noise Concrete pavement?
Provides better and smoother rides
Diamond grinding textures are low noise and provide a more uniform, smooth ride.
Provides better safety
When diamond grinding is used to create grooves on concrete pavement, the road maintains its texture for longer periods of time and improves traction, especially in wet weather.
The diamond grinding grooves will improve the road's long-term safety in comparison to roads without them.
Lesser cost of maintenance and also Lower Initial Cost
The concrete pavement's diamond texture was made at a modest cost. Due to this, the initial project cost was not significantly increased by the diamond grinding procedure.
As a result of the diamond grinding texture on concrete pavements being found to be satisfactory and durable, the maintenance cost is very low as a result of the diamond grinding surface.
How is diamond grinding used on both newly built and worn-out roads?

In the case of newly constructed roads, low-noise textures can be made by making only one pass, whereas, in the case of rehabilitating aged pavements, three passes can be made.
Joint stepping is eliminated in the first pass, followed by surface cleansing in the second and cutting grooves with 12.5 mm centres in the third.
