Abstract

As densification occurs in the Northeast, a growing number of residents are being affected by highway noise. The main source of highway noise has been shown to originate at the tire/pavement interface. In an effort to quantify this problem the Center for Advanced Infrastructure and Transportation has been utilizing the On-Board Sound Intensity method which directly measures the sound intensity originating near the tire/pavement interface. With this technique it has been inherently difficult to discretely compare different road surface treatments and their unique acoustical properties once in-service. In an attempt to be able to mathematically distinguish whether or not pavement surface types have similar acoustical properties a statistical analysis approach was followed throughout the paper. Along with statistically comparing each one-third octave band, the job mix formulas for the asphalt pavements tested were analyzed in an attempt to explain either similarities or differences between the acoustic properties of the asphalt surface treatments. Within this paper multiple types of Dense Graded, Open Graded Friction Course and Asphalt Rubber Gap Graded surface treatments were analyzed.
