Inset Photo 1: Fine aggregate structure facilitates placement and compaction. Above, Photo 2: Cores obtained for testing.

PG 58-28 binder was specified for
the traffic type, and 25 percent
reclaimed asphalt pavement
(RAP) was also incorporated. The
RAP was processed according
to the Ohio Department of
Transportation (ODOT) specs so
it was of sufficiently small size to
be incorporated in the mixture.
Observed in Inset Photo 1 is the
aggregate structure that allows for
thin asphalt layers. In Photo 2, the
fineness of the gradation facilitated
compaction though minor rutting
in the existing pavement resulted
in the course thickness having
some variability. When tested to
determine how well the mat was
compacted, the pavement was found
sufficient to resist permeability.

Compaction equipment
consisted of two highway-class
static (non-vibratory) steel wheel
rollers. Vibratory compaction
is not desirable on Thinlay
pavements. Potential for aggregate
degradation rises under the force
of such compaction equipment.
For this reason ODOT & Materials
Specification (C&MS) section 401.16
notes, "Do not use vibratory rollers
on courses with a thickness under 1.5
inches (38 mm)."
The Thinlay specification
controls compaction using the
method prescribed by ODOT in
C&MS section 401.16. Rolling must
be conducted using equipment
specified in section 401.13 and
sufficient for the rate at which

the Thinlay pavement is spread. A
three-wheel roller is required and is
operated in the breakdown position
of the roller train. The "break
down" position is first roller and
immediately behind the paver.

Clermont County,
State Route 743
ODOT let to contract Thinlay
preservation field trials in Districts
8 and 10. Combined, the trials took
place on four state routes; the first
to be paved was Clermont County
SR 743 (CLE-743) located in the
deep southwest part of Ohio, near
the Ohio River. Road profile varies
somewhat with the Southern Ohio
terrain. The pavement condition
