Low-noise concrete block paving
Road noise makes you sick – a statement that hardly anyone would contradict nowadays. The traffic noise situation can be improved by noise reducing road surfaces. The research projects presented here aim at reduction of sound emissions from concrete block paving.
For pavement construction, the current situation is such that a correction value of + 3 to + 6 dB(A) has been assigned to the now outdated RLS-90 directive for noise protection on roads. In comparison to other construction methods, the covering was given a penalty in acoustically sensitive areas such as residential streets. But in practice, the installation of roads built with concrete block paving in urban locations of this kind is extremely sensible due to the creative and ecological benefits. While there were numerous developments, such as open-pored asphalt, in recent years for the...
