TEST SECTIONS OF NOISELESS CEMENT CONCRETE PAVEMENTS

Abstract

In the quest to enhance road infrastructure with noise reduction and sustainability in focus, the Flemish Brabant Roads Division in Belgium initiated an innovative project on the N255 "Edingen-Ninove" road. This initiative involved the renewal of a 3 km stretch near Herne and Galmaarden, leveraging the opportunity to compare noiseless cement concrete pavements with traditional noiseless bituminous pavements. Collaborating with notable research institutions and leveraging advancements in concrete mixture compositions and construction techniques, the project aimed to evaluate acoustic performance, constructional aspects, and financial implications of four distinct types of pavement surfaces: porous asphalt, stone mastic asphalt, fine concrete, and porous concrete, each layered over a continuously reinforced cement concrete base.

The study meticulously analyzed each pavement type's acoustic characteristics, road constructional aspects, and financial considerations. Initial findings revealed promising noise reduction capabilities, especially with fine concrete pavements, showcasing their potential as a viable alternative to bituminous options. The research underscored the complexity of optimizing pavement surfaces for noise reduction, highlighting significant variables like texture, levelness, and material porosity. While acknowledging the preliminary nature of these results, the initiative marks a significant step towards sustainable and community-friendly road construction practices, offering valuable insights into the balance between environmental considerations and infrastructure development.
