A PERVIOUS CEMENT CONCRETE WEARING COURSE BELOW 73 DB(A)

This article presents an innovative approach to addressing traffic noise pollution through the development of a pervious cement concrete wearing course capable of achieving noise levels below 73 dB(A). Focusing on noise attenuation as a critical quality of service for road users, the study explores two primary strategies: reducing noise emission at the source and implementing absorbent structures to mitigate noise transmission. By examining the impact of road surface materials on noise levels, the research introduces a specific pervious cement concrete formulation designed to offer significant noise reduction benefits. The collaborative effort between laboratory studies and construction companies underscores the practical application and feasibility of this solution in real-world settings. Highlighting the material's effectiveness in not only reducing ambient noise but also in contributing to the overall improvement of road infrastructure quality, the study positions pervious cement concrete as a valuable tool in the quest for quieter, more comfortable urban environments.
