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.
