In hot asphalt mixtures, noise is generated in the vicinity of highways due to the friction between the wheel and the road surface. This causes noise pollution especially in settlement areas.
Studies conducted in Austria have found that 60% of noise pollution is caused by traffic.
In order to reduce the noise from friction between the road surface and the wheels, Various grades of resin-based additives and special graded hot asphalt blends have been developed.
In the trial studies; Noise-reducing asphalt has been found to be reduced by 5 decibels compared to the noisy normal blend.
Silent Asphalt, which can be applied on all kinds of road coverings, is preferred around the places where silence such as school, hospital, nursing home, etc. is important.
