Low noise pavements can be either elastic, such as rubberized asphalt, or porous as porous or drain asphalt, or both (poroelastic pavements). Rubberized asphalt is already in use in many areas ( Vázquez and Paje, 2016 , Licitra et al., 2015 , Sandberg, 2010 ), and reductions compared to standard pavements are in the order of 3 – 10 dB.
