Abstract

For the past two years, the Center for Advanced Infrastructure and Transportation has used the On-Board Sound Intensity Method (OBSI) to examine tire/pavement noise on in-service pavements throughout NJ and the northeast United States. The research initiative originated as a result of the NJ Department of Transportation's (NJDOT's) pavement resource program, which monitors the conditions of NJ roadways and provides engineering-based research about mechanistic pavement design, pavement material characterization, and pavement evaluation. NJDOT is interested in a long-term evaluation of the effects of the age and condition of asphalt pavement on the noise generated at the tire-pavement interface. Of the vast number of asphalt pavement design types found on interstates in NJ, Superpave-based dense graded asphalt (DGA) mixes and open-graded friction course (OGFC) mixes constitute the majority. Throughout the analysis of the OBSI levels measured, patterns that would be beneficial to the industry were illustrated in the one-third octave band profile for each pavement type. This paper provides a brief background of the OBSI method utilized in NJ and MA, an explanation of the analysis utilized to evaluate these pavements, and an explanation of the different spectral signatures attributed to DGA and OGFC pavements.
