The Poroelastic Road Surface (PERS): Is the 10 dB Reducing Pavement within Reach?

Effects of material composition on mechanical and acoustic performance of poroelastic road surface (PERS)

“…Although PERS exhibits outstanding performance in noise reduction, it also faces the challenging problem of mechanical ravelling, which significantly reduces its service life and limits its wider application [12][13]. As FIGURE 1 shows, the poor ravelling resistance of PERS is mainly caused by its open-graded structure, which does not provide enough granule-to-granule contact surfaces to withstand the imposed shear loading, particularly in the areas of sharp bends or during the processes of braking or accelerating.…”

Suitability of PoroElastic Road Surface (PERS) for urban roads in cold regions: Mechanical and functional performance assessment

“…The existing studies have proved that PERS provided outstanding performance in tire-road noise reduction, which was up to 10-12 dB(A), while the quietest conventional low-noise pavement, double-layer PA, rarely yields reductions exceeding 7 dB(A) (Sandberg and Goubert, 2011, Kalman et al, 2011, Pigasse et al, 2012, Sandberg and Gucbert, 2011, Biligiri et al, 2013. Although PERS provides outstanding performance in noise reduction, it faces the performance concern of low ravelling resistance, which significantly reduces its service life and prevents it from wider application (Goubert et al, 2016, Goubert, 2014, Schacht et al, 2011. In the authors' previous studies (Wang et al, 2017, Schacht et al, 2011, 20 PERS mixtures with different compositions were designed and characterized after various stages of polishing applied by the Aachener-Raveling-Tester (ARTe) (Wang et al, 2015, Wang et al, 2013, Wang et al, 2014.…”

A Review on Acoustic and Skid Resistance Solutions for Road Pavements

“…Studies conducted by Goubert [54] and Ejsmont et al [57] stated that the noise reduction could be as high as 12 dB(A), and the skid resistance was around 60 BPN, which was acceptable. However, more studies should be conducted to assess the skid resistance values' consistency [59].…”
