Developing quieter concrete pavements.

The American Concrete Pavement Association (ACPA) is conducting research to develop quieter concrete pavements to better serve the transportation community. This effort involves standardization of tire/pavement noise assessment; establishment of acoustic performance curves for existing surfaces; development of new surface textures through a laboratory test program; a field validation program; and an implementation phase. The research presented in this paper is concerned primarily with exterior vehicle noise. Although both interior and exterior noise is important to the consumer, most agency regulations involve only exterior noise and as such this is the focus of the current research.
