The urban development that has occurred in Portugal in the last decades of the 20th century was accompanied by a\ fast growth of road traffic and, consequently, by the construction of rural and urban roadways. After 1980, the\ noise control policies lead the road administrations and constructors to apply noise mitigation measures, like\ barriers but also pavements with noise reduction characteristics. In both cases, the evaluation of the acoustic\ performance allows a comparison of the design specifications with real performance data and its verification at the\ long run for an adequate validation of the adopted solutions. In this work the essential methods for an effective\ road noise management that allow the evaluation of road/tyre noise and of the acoustic performance of noise\ reduction devices, such as noise barriers. A method for the determination of the sound absorption in road
pavements is also presented.
