Analysis and Design of Pavement Surface Mixtures for Traffic Noise Reduction

项目名称：	Analysis and Design of Pavement Surface Mixtures for Traffic Noise Reduction
摘要：	The objective of this project is to analyze the relationship between mixture design variables and acoustic performance of pavement surface and to develop a design procedure or guideline for pavement surface mixtures that considers not only conventional functions (e.g., friction and permeability) but also noise reduction. The focus of the project is to examine the current designs of open-graded friction course (OGFC) mixtures, which are widely applied on highways in some states such as Florida, to see what adjustments may be made to improve their acoustic performance. The research team will perform literature review on the state-of-art of research on quiet pavements, investigate the relationship between mixture design variables (primarily aggregate gradation, shape, and air-void content) and mixture acoustic performance based on data collected from the literature and numerical analysis, and develop design recommendations for pavement surface mixtures for improved acoustic performance.
