Abstract

Tire-road noise levels for Ohio Department of Transportation pavement types were investigated to provide an additional criterion for pavement selection in noise-sensitive areas. Tire-road noise measurements were conducted in accordance with the International Organization for Standardization's statistical pass-by method (ISO 11819-1)--the first use of this standard in the United States. A statistical pass-by index (SPBI) was determined for each pavement test, which enabled the ranking of the pavement types according to tire-road noise levels, as well as a means of comparing results with other studies conducted according to the standard. There was a difference of 6.7 dB between the lowest (open-graded asphalt) and the highest (random-transverse-grooved concrete) SPBI for all of the pavements measured. Additionally, the data were analyzed to produce reference energy mean emission levels for future use with traffic-noise prediction modeling.
