Absorption instead of reflection

GS TerraElast used as pavement absorbs noise at the source.

Noise emission on standard roads is reduced by 8 dB at only 50km/h (noise reduction by 3 dB corresponds to 50% less noise to the human ear).

Most of the noise caused by road traffic is the result of rolling resistance.

Air is compressed between the tire and the road surface until it escapes in a miniature explosion.

With GS TerraElast, noise is discharged into the road surface.

GS TerraElast pavement prevents compression due to a large number of open cavities. Air escapes into the road surface.

Müller-BBM report dated 20/06/2007
(sound insulation experts)
“(...) at 50 km/h (passenger vehicles / trucks), the GS TerraElast pavement system (sandwich architecture) generates 2-3 dB less noise than the quietest version of standard dual-layer open-pore asphalt currently available” (latest OPA2 ultra-quiet asphalt)
