The objective of this investigation was to develop a model to predict on-board sound intensity (OBSI) on hot mix asphalt pavements using on-site and laboratory data. The data used included noise and physical property data collected on 25 asphalt-surfaced roadway test sections at the MnROAD pavement testing facility. These test sections were constructed mainly in 2007 and 2008 using a variety of materials, mixtures and layer thicknesses. A modeling approach called the mechanism decomposition approach was used to develop the models. In this approach, the contributions of different noise mechanisms to the overall noise level and to noise in certain frequency ranges are modeled separately then are combined to form the total noise spectrum. Ultimately, two nonlinear statistical models were developed that predict one-third octave band and overall sound intensity levels on asphalt-surfaced pavements. The models incorporate the pavement parameters that were found to have the most significant effects on tire-pavement noise including pavement macrotexture, air temperature, modulus of the pavement surface layer, and the combined effect of temperature and modulus. The models differ in the type of texture data used as an input parameter. The models have been found to predict the overall OBSI sound intensity level to within 1.5 dB and the onethird octave bands to within 2 dB for most of the pavements tested. Other metrics and evaluation of the model accuracy by cell, year, temperature and other factors are also reported. The models are provided in an Excel spreadsheet.

As one measure to reduce traffic noise, designing a noise-reducing ("quiet") pavement surface has received increasing attention. For asphalt pavements, some existing asphalt mixtures have shown better noise-reducing capabilities than conventional dense-graded asphalt concrete (DGAC) pavements. To design a new asphalt mixture optimized for noise reduction, the acoustic performance of existing asphalt-surface mixtures needs to be evaluated and understood. For this purpose, a study was conducted to measure tire/pavement noise on a variety of asphalt pavements for four consecutive years. The tire/pavement noise was measured with an on-board sound-intensity (OBSI) method that was continuously improved during the study. Regression analysis was applied to determine the levels and increase rates of tire/pavement noise on four major asphalt mixtures, and the effects of mix design variables on tire/pavement noise. Results show that tire/pavement noise generally increases with pavement age on all types of asphalt pavements. For newly placed or overlaid pavements, open-graded or rubberized gap-graded mixtures exhibit lower noise levels than conventional dense-graded asphalt mixture. Open-graded asphalt mixtures can retain noise-reduction benefit for a longer period than gap-graded mixtures. Using rubberized binders in the open-graded mixtures can further reduce the noise-increase rate. Pavement surface permeability, macrotexture, and existing surface distresses may affect the tire/pavement noise level.
