SILVIA (= SILenda VIA) aims to help reducing traffic noise by optimising the system vehicle (reduction potential 3 - 4 dB) - tyres (1 - 4 dB) - surface (4 - 6 dB).
The SILVIA project aims at providing decision-makers with a tool allowing them to rationally plan traffic noise control measures. To this end, the work will aim at filling three major knowledge and technical gaps, namely by: setting up classification and conformity-of-production procedures of road pavements with respect to their influence on traffic noise, investigating and improving - based on existing data and laboratory and field testing - the functional and structural durability of low-noise pavement construction and maintenance techniques, and developing a full life-cycle cost/benefit analysis procedure for traffic noise abatement measures. The main final product will be a "European Guidance Manual on the Utilisation of Low-Noise Road Surfacing" integrating low-noise surfaces with other traffic noise control measures including vehicle and tyre noise regulation, traffic management and road and building noise protection equipment.
