In recent years various types of asphalt surfaces have become identified as quiet pavements due to their ability to reduce tire/pavement noise and ultimately traffic noise Often lost in this perception is the fact that substantial reductions in tire/pavement noise can also be made by texture modifications to existing Portland Cement Concrete PCC or by novel constructions
In this investigation studies have been done to understand the effects of various grinding and grooving parameters to investigate their effect on noise generation at the tire‐pavement interface Grinding uses diamond‐infused blades that are closely‐spaced such that the fins between the blade tracks break off exposing an entirely new surface
