  • Abstract:
    Since 2003, the Arizona Department of Transportation (ADOT) has been conducting a Quiet Pavement

    Pilot Program (QPPP) in cooperation with the Federal Highway Administration (FHWA). This report

    presents the noise findings of this research through 2007. The initial reduction in noise levels achieved

    by overlaying portland cement concrete pavement (PCCP) on freeways in the greater Phoenix area with

    asphalt rubber friction course (ARFC) were documented with three types of measurements: 1.)

    tire/pavement noise levels measured on-board a test vehicle near a test tire (Site 1), 2.) neighborhood

    noise levels measured at typical receiver locations in the vicinity of the freeways (Site 2), and 3.)

    wayside tire/pavement noise levels measured at five research grade sites (Site 3). The initial reductions

    ranged on average from 5.5 to 9 dB depending on the type of measurement and the specific location. In

    subsequent years, measurements were conducted to assess the noise reduction performance of the AFRC

    over time or the acoustic longevity of the pavement. For the Site 1 and 3 data, the noise reduction has

    dropped by about 2 dB on average over the four years since the overlay was installed while the Site 2

    levels have shown less than a 1 dB reduction. The results of the Site 3 measurements were compared to

    the results calculated from the FWHA Traffic Noise Model (TNM) using TNM Average Pavement.

    Through 2007, the measured noise levels at the tire/pavement interface have been 4 dB or more lower

    than the TNM predictions for the 50 ft and 100 ft distant microphone locations except for the 50 ft

    position (only) at one of the Site 3 locations.
