Formed in 1989 as the Forum of European National Highway Research Laboratories, FEHRL is governed by the Directors of each of the national institutes. At present, FEHRL comprises twenty-nine national laboratories from the member states in the European Union, the EFTA countries and the rest of Europe. Under the day-to-day management of the Executive Committee,FEHRL is engaged in research topics including road safety, materials, environmental issues, telematics and economic evaluation. Research capacity is provided by the national institutes and makes use of the wide range of test facilities available. AIMS AND OBJECTIVES The mission of FEHRL is to promote and facilitate collaboration between its insti- tutes and provide high quality information and advice to governments, the European Commission, the road industry and road users on technologies and poli- cies related to roads. The objectives of collaborative research are: - to provide input to EU and national government policy on highway infras- tructure - to create and maintain an efficient and safe road network in Europe - to increase the competitiveness of European road construction and road- using industries - to improve the energy efficiency of highway construction and maintenance - to protect the environment and improve quality of life FEHRL Report 2006/02 Guidance manual for the implementation of low-noise road surfaces FEHRL Report 2006/02 Guidance manual for the implementation of low-noise road surfaces i This Guidance Manual has been prepared as part of the EU Fifth Framework Project “SILVIA – Sustainable Road Surfaces for Traffic Noise Control”. SILVIA was initiated by FEHRL, with the leadership designated to the Belgian Road Research Centre (Mr Guy Descornet). This document is dedicated to Mr Rod Addis, the former Secretary-General of FEHRL, whose untimely death in 2004 prevented him from seeing the successful conclusion of the project which he so ably supported. The project consortium brings together 15 partners from both FEHRL and other organisations.
