• Abstract:
  In response to an interest in traffic noise, particularly tire–pavement noise, CDOT elected to conduct tirepavement ; noise research. Following a rigid set of testing protocols, data was collected on highway traffic ; noise characteristics along with safety and durability aspects of the associated pavements. This report ; completes a comprehensive, long-term study to determine if particular pavement surface types and/or ; textures can be used as quieter pavements, and possibly be used to help satisfy FHWA noise mitigation ; requirements. The study addressed: The noise generation/reduction characteristics of pavements as functions of pavement type, pavement ; texture, age, time, traffic loading, and distance away from the pavement; Correlations between source measurements using on-board sound intensity (OBSI) and wayside ; measurements including both statistical pass-by (SPB) and time-averaged measurements; and The collection of data that can be used for validation and verification of the accuracy of the FHWA ; Traffic Noise Model (TNM) to use on future Colorado highway projects. ; Implementation: ; There are numerous findings from this study, along with associated implementation activities. The most ; promising finding is that each of the common pavement types in use by CDOT has the potential for quieter ; variants. As a result, implementation of this study could include the identification and specification of the ; specific asphalt mixtures and concrete textures that result in quieter pavements without compromising on ; safety or durability.
