Abstract: Road traffic noise contributes significantly to outdoor environmental noise, especially in urban areas. The pressure of traffic noise is influenced by many factors such as types of engines, exhaust systems and tires interacting with the road, weather and road conditions. The tire/pavement interaction noise has been proven to be the major source of the traffic noise, especially for cruising driving conditions, which is highly influenced by surface characteristics of road pavement. Traffic flow is also a factor – apart from vehicles, tires and road surface characteristics – in affecting traffic noise pressures. The noise level can increase by about 3 dBA when traffic flow doubles, if the traffic composition, speed and driving patterns are constant. Consequently, it is required to investigate the effects of road pavement conditions and traffic flow on traffic noise emission, and further explore the interactive effect of operation time of pavement and traffic flow for traffic noise control and mitigation. In this research, a series of field experiments are conducted on highways of new and old pavements. The variations of traffic flow and traffic noise pressure levels together with the functional relationships between them are analyzed based on the noise data collected from the highways in an urban area. With the collected data, the maximum traffic flow and traffic noise pressure levels are determined in a specified time manner. Logarithmic functional relationships are found between traffic noise pressure level and traffic flow for both old and new pavements. It is also found that the improvement in pavement material of highway may promote the absorption of traffic noise. A single value index is developed for quantitatively and conveniently evaluating the acoustic quality of highways
