Noise pollution and asphalt paving

Noise, including road noise, is a pervasive form of environmental pollution. There is no better way to reduce road noise pollution than to treat the problem at its source. By paving roads and highways with asphalt, the noise pollution generated by at the tire-pavement interface – noise that affects people as they go about their daily lives – can be significantly reduced. Paving with asphalt is actually more effective than building expensive, unsightly noise walls. We can all do our part to help noise pollution.

What is noise pollution?

Irritating noise from environment: irritating, distracting, or physically dangerous noise to which people are exposed in their environment and over which they usually have no control. (Definition from)

Wiki Info On asphalt, and noise pollution: LINK

Asphalt concrete has different performance characteristics in terms of surface durability, tire wear, braking efficiency and roadway noise. The appropriate asphalt performance characteristic is obtained by the traffic level amount in categories A,B,C,D,E, and friction coarse (FC-5). Asphalt concrete generates less roadway noise than Portland cement concrete surfacing, and is typically less noisy than chip seal surfaces. Tire noise effects are amplified at higher operating speeds. Noise is generated through the conversion of kinetic energy to sound waves. The idea that highway design could be influenced by acoustical engineering considerations including selection of surface paving types arose in the very early 1970s.[5][6]
