QUESTIM

Road traffic noise is regarded as a major concern for the quality of the environment and the health of people living close to roads. Although façade insulation and noise barriers can reduce indoor levels, low noise road surfaces have the potential to reduce outside noise levels without the costs and visual hindrance of barriers... Road authorities in Europe, organized within CEDR, have combined financial resources to explore the durability and cost/benefit relations of these noise reducing surfaces and noise barriers and to develop schemes for implementing low noise surfaces in Pavement Management Systems. A consortium consisting of Aalto University from Finland, TRL from the United Kingdom and Müller-BBM from Germany, coordinated by M+ P from the Netherlands was awarded a research contract on the basis of their QUESTIM proposal... It is the objective of this study to generate information on the aspects inhibiting wider application of low noise surfaces and innovative barrier designs..
