Highway traffic noise is an important issue in the U.S. As activity volumes increment, commotion levels increment. At the same time, numerous groups are trying to enhance the quality of life by reducing the noise. Hence, highway traffic noise has turned into a component of the pressure between economic development and quality of life.

At freeway speeds for well-maintained vehicles, the primary source of traffic noise is tire-pavement noise. Thus, the tire-pavement interface is the primary target of studies to reduce traffic noise. Quieter pavement has been demonstrated in several communities in the U.S. Based on such case studies it is possible to construct and maintain pavements that are quieter than typical pavements that are also safe, durable and cost-effective.

This report includes the introduction of generation of noise and its enhancement due to the interface between tire and pavement. It also includes a brief description on On-board Sound Intensity (OBSI) and how it is installed on a test car. Introduction to Next Generation Concrete Surface and Next Generation Diamond Grinding, as well as a comparison between the NGDG and transverse-tinned pavement surface texturing in regards to noise, cost, skid-resistance and ride quality.
