Porous Urban Pavements in Cement Concrete

Questions regarding the environment are being particularly felt in certain countries, and noise con-trol requirements have led to the development ofthin free draining materials able to limit tirepavement contact noise.We shallbe dealingherenotwith a thin free draining pavement structure, butwith a porous concrete pavement of 40 cm thick-ness. Theoretical studies have in fact shown thevalidity of such a thickness as concerns decibel re-duction. The paper describes an experimental pro-ject embodying a new approach to the design ofurban pavements.
