depot parking areas and dams, but
its inherent roughness has made
it seldom-used for highway pave-
ments. The Virginia DOT, however,
has placed its first RCC pavement
and is evaluating it for performance,
according to a 2015 TRB paper.

RCC is a relatively stiff mixture
of aggregate, cementitious materials
and water that is placed using asphalt
pavers instead of slipform pavers, is
compacted by vibratory rollers and
hardens into concrete. It contains
a low amount of water, exhibits no
slump, and can be placed and opened
to traffic in a short period of time.

central plant recycler adjacent
to project; foamed asphalt- and
cement-stabilized material were
placed above stabilized stone base.
