Abstract
Traffic noise is one of the most important environmental problems in densely populated urban areas. At low speeds the tyre/road interaction dominates all other sources. It is anticipated that when electric and hybrid vehicles gain dominance in city traffic, the importance of tyre/road noise will still increase as electric engines are much less noisy than combustion engines. On the other hand, electric and hybrid urban vehicles are less powerful than conventional cars, thus they may allow for different road surface solutions and tyres of unconventional construction. One of the candidate road surfaces for urban applications is the so called poroelastic road surface "PERS" composed from rubber aggregate, mineral chippings and polyurethane resin. Road surfaces of this type are being developed in Japan and Europe. The paper discusses acoustical properties of such surfaces as well as some practical and environmental aspects of their production and usage. The results are based on research project PERSUADE that is funded by the European Commission. The aim of the project is to develop a road surface that will reduce tyre/road noise to a great extent but will not have adverse effects on fuel consumption and broadly defined safety (skid resistance, fire risk, biological dangers).
