• Abstract:
  The Volpe Center Acoustics Facility, in support of the California Department of
  
  Transportation (Caltrans), has begun a five-year study to assess several types of pavement for
  
  the purpose of noise abatement. On Highway 138 in Southern California (a desert area about
  
  20 miles west of Lancaster), a 6.4-kilometer (4-mi) stretch of roadway has been chosen as the
  
  site for pavement overlays. A preliminary measurement program determined that the existing
  
  pavement on this roadway was highly irregular and in need of repair. As such, this stretch of
  
  Highway 138 will first be treated with a leveling course in order to have uniform base
  
  pavement, after which 4 or 5 different types of pavement will be overlaid in long sections, the
  
  shortest being 0.4 km (0.25 mi). The leveling course will be dense-graded asphalt concrete
  
  (DGAC), and the pavement types for the overlays are expected to include open-graded
  
  asphalt concrete (OGAC) with varying depths, rubberized asphalt concrete (RAC), and
  
  bonded wearing course (BWC). The overlay sections are referred to as the test sections.
  
  Two sections of the uniform base will remain untouched without any overlays; these sections
  
  are referred to as the reference sections.
