DRI-DWW thin layer project : final report

A project on developing and testing optimized noise reducing thin layer pavements is a part of DRI-DWW noise abatement programme [1]. This programme is a co-operation between The Danish Road Institute/Road Directorate (DRI) and Road and Hydraulic Engineering Institute in the Netherlands (DWW) in the period from 2004 to 2007. A total of 7 research and development projects are carried out inside the framework of this program [1]. The DRI-DWW noise abatement programme is a part of the Dutch IPG program on development and testing of noise reducing measures for road traffic [2]. This final report is Milestone M7 in the thin layer project. The objective of the report is to give an overview of the project as well as to present the final results.
