Thinlay Projects On The Ground
see when applying a preservation
treatment (Photo 6). FPO notes in
its Thinlay technical bulletin the
following: "Thinlay should be used
wherever pavement preservation is the
objective of a treatment. It should be
placed on structurally sound pavements
that are exhibiting only surface distress.
Raveling and minor cracking due to
oxidation are the types of distresses for
which a Thinlay is ideally suited."

Vinton County,
U.S. Route 50
The final Thinlay placed this year
was part of ODOT's Low Volume
Test Road research. VIN-US50 is
located east of Chillicothe in ODOT
District 10. Ohio University was
contracted as the research team.
Research goals of phase 1 are to
evaluate various asphalt strategies
that will extend the performance
life of asphalt mixtures used for
low-volume traffic applications.
Thinlay is among the strategies
being researched. The paving
contractor was Shelly & Sands
Inc. and the asphalt producer was
MarZane Inc.
VIN-50 is a composite pavement

base). To ensure the pavement was
suitable for preservation treatments,
the contract included repairs to
bring it to a structurally sound
condition. The Thinlay was placed
at a 0.75-inch thickness.

Mixture composition used
PG 64-22 binder, binder content
of 6.8 percent (eight-tenths greater
than the Type 1 control mix),
and proportions of limestone
coarse aggregate combined
with manufactured and natural
sands to meet the gradation
requirements). Note: The Thinlay
aggregate gradation specifications
were designed to ensure the
proportions of coarse to fine
aggregate are constant regardless
of project location and aggregate
mineralogy. This is what ensures
a consistent gradation that is less
prone to segregation - highly
likely to be uniform in texture
- wherever thinlay is used. As
in the case of the previously
placed Thinlay projects, the VIN50 Thinlay pavement exhibited
exceptional surface texture
uniformity. AP
