Learning from others - New Jersey Report

New Jersey published a report in May of 2004 “Demonstration Project - The Measurement of Pavement Noise on New Jersey Pavements Using the NCAT Noise Trailer” (click on link to see full report)

It is clear that both the surface of the road surface matters and the speed of the traffic - we need to focus on both of these factors!

Here are some excerpts that may interest you! 

• Traffic noise is a serious problem. Engine, exhaust, aerodynamic (power train) noise, and pavement/tire noise contribute to traffic noise.  

   
  

• Research in Europe and the United States has indicated that it is possible to build pavement surfaces that will provide low noise roadways. 

• Based on the results, one can basically expect a 0.2 dB(A) increase in tire/pavement related noise for every 1 mph increase in traffic speed. 

• In general, the Portland Concrete (PCC) sections produced the loudest pavement surface while the Open-graded Friction Course (OGFC) produced the lowest pavement/tire noise.
