Thinlay Projects
On The Ground

Pavement preservation projects in Ohio

T

hinlay™ asphalt
mixtures made their
debut this construction
season beginning
with the placement of
Thinlay preservation treatments
in Darke, Vinton, Clermont,
and Preble counties. The trials
demonstrated Ohio's Thinlay could
be placed in a 0.75 inch thin course
and with a consistently uniform
texture - a factor important

to pavement preservation and
overall pavement durability.
The functions of Thinlay are to
seal a pavement, correct functional
(non-structural) pavement distresses,
provide (modest) structural strength
improvement, true-up a pavement
by restoring profile and cross-slope,
and improving smoothness. In
accomplishing these preservation
objectives, the overall life cycle
cost of a pavement can be reduced

Darke County,
Arnold Road,
The paving of Arnold Road, Darke
County, in mid-August was the
first Thinlay placement in Ohio.
Working in cooperation with
Darke County Engineer Jim Surber,
P.E., P.S., the Walls Brothers
Asphalt Co. Inc. of Greenville
placed a 0.75 inch Thinlay. The
pavement is classified as "light
traffic," based on the relatively
few vehicles that use Arnold Road.
However, Arnold Road is subject to
seasonally heavy traffic as the time
for harvest arrives, bringing with it
substantial agricultural traffic. The
unique traffic condition provides a
good test for Thinlay durability.
Pavement condition is a factor
in the selection of preservation
treatments such as Thinlay. Arnold
Road, being lightly travelled, had
all the signs of a pavement that was
suffering from oxidation and minor
cracking - the types of distresses
Thinlay preservation treatments
were developed to fend.
The Arnold Road mixture
used 100 percent crushed coarse
aggregate and the fine aggregate
portion of the mix consisted
of nearly equal portions of
limestone sand and natural sand.
