The article gives a study of factors influencing noise emissions from the interaction of the tyre and road surface. Theoretical principles of asphalt pavements with optimised noise reducing characteristics are identified in the paper. In accordance with the experience of implementation and exploitation of noise reducing asphalt mixtures in other European countries, two concepts of noise reducing pavements were prepared for Lithuanian conditions. Laboratory tests were performed for these conceptual asphalt mixtures and other asphalt mixtures with promising noise reducing characteristics. Physical and mechanical characteristics of different noise reducing asphalt mixtures were determined, compared and evaluated. With regards to the research results, article concludes with recommendations of noise reducing asphalt mixtures suitability for implementation in Lithuanian road network.

Keywords: tyre/road noise; noice reducing asphalt pavements; laboratory tests.
