摘要

The last decades more silent types of cement concrete road surfaces have been developed, like the exposed aggregate cement concrete (EACC). In Belgium this type is nowadays very popular for its excellent durability (resistance to rutting and raveling). The acoustic quality is also an important aspect. In this paper the acoustic quality of different EACC roads in Belgium is assessed using the Statistical Pass-By method. Texture measurements were carried out on the same locations and used to predict the noisiness with the ENDt model, in order to validate this model for EACC. Goals of the research are to develop a method to assess the acoustic quality and homogeneity of EACC roads. The combination of the fast and efficient (and hence cheap) texture measurements, combined with a thoroughly validated ENDt model will be an efficient tool for conformity of production with respect to the acoustic quality.
