Continued policy changes are certain as quieter pavements become increasingly utilized.
Austin, TX (PRWEB) November 29, 2012
Pavement engineering firm The Transtec Group reports on recent updates to three AASHTO provisional standards for pavement noise evaluation.
The transportation industry is moving forward with efforts to adopt a set of newly updated pavement noise evaluation standards into regular practice. The American Association of State Highway and Transportation Officials (AASHTO) recently released updates to Provisional Standards TP 76, 98, and 99. These standards – newly available to the public – refine technologies and methods used to measure pavement’s influence on vehicle and traffic noise.
This update recently prompted a Transportation Research Board (TRB) webinar for those invested in designing, building, and maintaining quieter pavements. Over 100 people attended “Quieter Pavements: Measurements and Applications,” a late October webinar developed by TRB’s Standing Committee ADC40 on Transportation-Related Noise and Vibration.
Webinar attendees – professionals from state DOTs, FHWA, and various organizations – learned the fundamentals of traffic, vehicle, and tire-pavement noise, and methods for measuring pavements’ influence on noise levels. TRB’s presenters – Paul Donavan of Illingworth & Rodkin, Inc., Judy Rochat of USDOT’s Volpe Center, and Dana Lodico of Lodico Acoustics LLC – emphasized TP 76, 98, and 99’s improvements to standard practice, demonstrating how the updated information may be used to quantify the performance of quieter pavements.
Continued policy changes are certain as quieter pavements become increasingly utilized – the industry’s understanding of road noise is expected to continue developing with ongoing research.
Those who were unable to attend TRB’s webinar but would like to request a recording may do so through TRB’s website.
