Water in Road strctures : movement drainage, and effects

Developing a new low noise road surface can be a very time-consuming and costly process. Thus, the use of SPERoN® , has clear advantages. The scope of this paper is to show how SPERoN® can assist on the development of an improved low noise surface. From the initial definition of the input physical parameters to the discussion on how the output quantities can be used in the design of the new road surface. The results of coast-by measurements will validate the SPERoN® outcomes and show the advantages of this approach. Finally, other applications of SPERoN® are presented such as, acoustic monitoring of roads, conformity of production of a new road surface, among others.
