Abstract: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.
