During the last several years, when performing numerous CPX noise measurements on low noise pavements,significant inhomogeneity of the wearing course was observed in numerous cases. Similar problems were almost not existing regarding to the dense pavements.In general three main reasons of inhomogeneity can be defined. The first one are imperfections in technology of production of a asphalt mix or/and errors made already during the laying process of the wearing course. The second is clogging that takes place during operation of the pavement. The third reason is related to uneven and/or excessive wear of the pavement (ravelling and stripping of the aggregate may appear in this case).The findings of analysis of noise data acquired on low noise pavements (based on 10m long segments) during measurements performed by the Gdansk University of Technology was presented and discussed in the paper. Problems related to the selection of representative section of inhomogeneous pavement when calculating the CPX Index were also discussed. Additionally, results of noise measurements of inhomogeneous wearing course performed by the Bialystok University of Technology using SPB method were presented. The influence of selection of SPB measuring point within the length of inhomogeneous pavement section was discussed.
