  • Abstract:
    The Kansas Department of Transportation (KDOT) began placing multi-layer polymer bridge deck overlays in 1999 and at the present time have over 200 in service. A few years after placing the overlays, individuals indicated that they noticed how quiet the bridges with the overlays were compared to tined concrete pavement and tined concrete bridge decks. The thought was that the angularity of the aggregate was causing general interference creating a dampening effect on the noise.

    Due to an increase in the feedback from the public on highway noise and the increase of traffic in highly populated areas, KDOT contracted with Kansas State University to evaluate the possible reduction in tire noise levels due to the polymer overlay systems. Arrangements were made for a brief evaluation to determine if further study would be worthwhile and investigate possible implementation as a tire noise reduction action.
