• Abstract:
  This experimental project is being conducted as a part of WSDOT’s effort to produce pavements that reduce the noise ; generated at the tire/pavement interface. Experimental sections of open-graded friction courses were built using asphalt rubber ; and SBS modified binders. A section of conventional Class ½ inch hot mix asphalt (HMA) serves as the control section for the ; two experimental sections. ; Sound intensity measurements were conducted using the On Board Sound Intensity (OBSI) method after construction. ; The most recent OBSI readings taken in December of 2009 indicated that the open-graded asphalt rubber and SBS modified ; sections were 3.5 to 2.0 decibels, respectively, quieter than the Class ½ inch HMA control section. ; This experimental evaluation will continue for the useful life of the pavement or a minimum of five years.
