Abstract:The current specifi cation of the Louisiana Department of Transportation and Development (LADOTD) calls for a ClassII crushed stone base layer in its fl exible pavement construction. Due to a lack of high-quality stone aggregates and
steadily increasing the costs of imported stone materials, LADOTD is continuously seeking for alternative base materials
in lieu of a regular stone base. This report documented the research eff orts conducted at the Louisiana Transportation
Research Center (LTRC) regarding foamed asphalt treated reclaimed asphalt pavement (RAP) alternative base materials
and provided detailed information on experiment design as well as conducted fi eld and laboratory tests. Note that this
report is one of a series of reports that document the results of a recently completed accelerated pavement testing
(APT) experiment conducted at the LTRC’s Pavement Research Facility (LTRC Research Project No. 03-2GT: Accelerated
Loading Evaluation of a Sub-base Layer on Pavement Performance).
