The Concrete Pavement Surface Characteristics Program (CPSCP) has recently developed guidelines and practices for reducing tire- pavement noise. The primary means for doing this is via measurements using the on-board sound intensity (OBSI) technique. OBSI measures tire-pavement noise at the source utilizing specialized microphones mounted to the outside of a vehicle, near the tire-pavement interface. Measurements are performed while the vehicle drives across the pavement being evaluated. To facilitate innovation, specifications have been developed based on an end-result approach. In this paper, a means for how to measure OBSI is provided, along with a means to interpret the as-constructed quality through visualization techniques. With it, the spatial variability of tire-pavement noise, as measured using OBSI, can be readily determined.

On Board Sound Intensity measurements were conducted on freeway segments in the vicinity of Las Vegas and Reno, Nevada in an effort to document the tire-pavement noise levels of existing pavements. Tested pavements included Portland Cement Concrete (PCC), Open Graded Friction Course (OGFC), and Rubberized Open Graded Friction Course (ROGFC) sections on US 95, I515, US 93, I-15, SR 160, and I-215 in the vicinity of Las Vegas and on I-80, and US 395 in the vicinity of Reno. In addition to the measurement and documentation of existing pavement sections, measurements were conducted prior to and after the placement of ROGFC on I-515 between the College Drive and West Horizon Drive Interchanges (Exits 57 and 59). This report summarizes the acoustical performance of the selected pavement sections, utilizing the results of on-board tire/pavement noise source measurements. A more detailed assessment of the I-515 overlay results were documented in a previous memo.

Mitigating transportation noise is a major concern for Departments of Transportation (DOT) nationwide. From a responsibility standpoint, once a noise source leaves the boundary of the property, the noise control falls under the jurisdiction of the DOT. In the past, mitigation by the DOT was typically accomplished by erecting a sound barrier. If there was more noise or louder noise, a larger wall was used. As construction of these walls is prohibitively expensive, DOTs are increasingly interested in mitigating noise from the source. In order to investigate noise being produced at the source, the on-board sound intensity method was utilized to investigate quiet pavements. The method revealed the acoustical properties of both conventional pavements and quiet pavements. This research also led to the investigation of the effects of vehicle speed, effects of temperature and effects of different consumer tires and the role each plays in the generation of noise at the tire pavement interface.
