Case Studies of a Low-Noise Road Surface
Source abstract
Abstract
The Statistical Pass-By Index (SPBI) for assessing the noise levels of road surfaces was used successfully on suburban roads where individual vehicles could be targeted with a sound meter and a radar speed meter. Reductions in SPBI of the order of 5 dB(A) were obtained when two noisy surfaces, a surface treatment and an overlaid jointed concrete pavement, were replaced with a rubber crumb modified bituminous surface. The noise reductions were strongly supported by a fundamental statistical analysis of the same data that was used to establish the indices. On an inner-city street with a heavy traffic density, it was necessary to rely entirely on a statistical analysis of the relationship between other sound parameters, Leq,L10 and L50, and noise weighted traffic flow to assess the benefit of the low-noise surface.
