2001 - Denmark - Technical Performance and Long-Term Noise Reduction of Porous Asphalt Pavements

This paper describes the results of the annual surface measurements in the period from 1990-1999 made in Denmark. The main objective for establishing the test sections was to examine how the noise reduction behaviour of the test sections performs on long term. But also issues, such as general performance and winter maintenance of these types of pavements were studied. These parameters are of vital performance for the road users as friction and evenness can have significant influence on both safety and economic aspects for the road users.
