Relationship between Road Surface Characteristics and Noise Emission

The paper summarizes the activities performed by the Roma La Sapienza Partner of the TINO Consortium to fulfill the task of characterizing the pavement texture and relating it to the far and near field noise measurement performed on the same pavements. The testing procedures and results are reported and the final statistical correlation found between texture and noise is described. A new texture index able to characterize the noise performance of the pavement surface and related to the pavement design and construction procedures is proposed.
