Experiences with Noise Reducing Surfaces for Existing Concrete Pavements

In Carinthia a surface dressing with epoxy resin as binder and chippings 3/4 mm has been used since 1989. The task was to get better noise reducing conditions of existing concrete pavements. The result can be seen in noise reducing properties of - 6 db(A) compared with the existing old pavement and a good skid resistance. Although the time of observation has been very short it can be said that a satisfactory longtime behaviour can be expected and that it is an economic construction method.
