In the spring of 2005, the Ministry of Transportation of Quebec (MTQ) developed a road dynamic audiometer (RDA) in order to use the close-proximity (or CPX) method to measure the noise generated by the interaction of a vehicle tire on pavement. A condition survey was conducted on several pavement types using the RDA. Parts of this survey were carried out simultaneously using the NCAT-CPX trailer, in cooperation with Auburn University in Alabama. The sound pressure level readings were taken n order to evaluate the quality of the measurements obtained with the RDA, and to compare the results on various textures of Portland cement concrete (PCC) pavement and on hot-mix overlays of various ages.
