NCAT Report on High-Modulus Asphalt Mixtures
for Use as Base Course
In June, the National Center for
Asphalt Technology (NCAT) at
Auburn University released Report
17-04: "High Modulus Asphalt
Concrete (HMAC) Mixtures for Use
as Base Course." The report publishes
research that evaluates the current
mixture design methodology of

high-modulus base layers using
European specifications for highmodulus asphalt concrete mixtures
and potential effects on performance
when used in the United States
as a base course. The European
specification includes volumetric
requirements such as asphalt

content and air voids, but there are
also requirements for engineering
parameters that address performance
requirements such as rutting and
fatigue cracking. The study was
limited to a laboratory performance
evaluation and a theoretical
modeling component where the
results were used to indicate potential
field performance. Access the full

As the asphalt pavement industry
continues to put greater emphasis
on pavement performance, it is
becoming more difficult to continue
to meet road owner and agency specs
requiring specific Superpave-based
"recipes." The answer is balanced
mix design - an approach to
designing asphalt mixtures so that
they reliably perform and those
performance requirements can be
lab tested. Already a number of states
across the country are beginning
to experiment with allowing
contractors to use a balanced mix
design that meets the departments
of transportation (DOTs) required
outcomes, instead of the DOTs
providing specs.
To ensure contractors are able
to successfully use balanced mix
design, NCAT is offering 2.5 day
workshops at their facility in
Auburn, Ala. Participants in the
workshop will gain enough skills and
understanding of the fundamental
principles of balanced mix design to
create design balanced asphalt mixes
in their company's asphalt labs.
The next two workshops are
scheduled for Nov. 7-9, 2017,
and Jan. 23-25, 2018. For more
