Abstract:

The purpose of this paper is to show statistical results of tire-pavement noise measured over twelve typical pavement surfaces in Virginia using three different devices. During the 2013 Annual Equipment Comparison Roundup at the Virginia Tech Transportation Institute, noise measurements were conducted in three different locations using the On Board Sound Intensity (OBSI) methodology over eight different asphalt surfaces and four different concrete surfaces. Tests were conducted using different equipment (different hardware and software) but all three complied with the OBSI Methodology stated in the American Association of State Highway and Transportation Officials (AASHTO) Standard Designation TP 76. The precision and bias in the results for each device were addressed following the standard. Statistical analysis was used to show the variability of the results due to the use of different devices. The conclusions show that the Open Graded Friction Course section is quietest, with an average of 100.4 A-weighted decibels (dBA). The microsurfaced section is loudest, with an average of 104.9 dBA. It is also revealed that traffic load and the aging effect significantly influence noise levels for the same type of surface. The study shows a difference of 3.5 dBA on average when comparing the same type of section with a 7 year difference between them. Finally, in terms of device comparisons, the overall average difference in noise levels between devices involved in the study is 0.6 dBA, with a maximum average difference of 1.3 dBA, for a single section, with an average standard deviation of 0.58.
