GOD BLESS AMERICA !
|We love to share our work with visitors! When driving in on I-85 (traveling from
either Montgomery, AL or Atlanta, GA), get off the interstate at Alabama's exit 62 (near
mile marker 62) and travel east on US 280. Drive 4.4 miles, then turn to the right
onto Lee Road 391. Drive 1.7 miles, then turn to the left onto Lee Road 151.
You will reach the main entrance to the Track (on the right) after traveling 1.5
miles. Turn right into the gate and enter the parking area after traveling only
about 0.2 miles. Please check in at the office when you arrive. To help you
navigate, directional signs have been posted from both I-85 and US 280 West all the way to
the main gate. Thanks ALDOT! If you are navigating by GPS, the Track is
located at 32°35.9' N latitude and 85°17.8' W longitude.|
Our facility is located about 30 minutes
from the campus of Auburn University. Managed by the National Center for Asphalt
Technology (NCAT), the Pavement Test Track provides a rare opportunity for sponsors to
answer specific questions related to flexible pavement performance in a full scale,
accelerated manner where results do not require laboratory scale extrapolations or
lifelong field observations.
Experimental sections on the Pavement
Test Track are cooperatively funded by external sponsors, most commonly state DOTs,
with subsequent operation and research managed by NCAT. Forty-six different
flexible pavements have been installed at the facility, each at a length of
approximately 200 feet.
Materials and methods unique to section sponsors were imported during
construction to maximize the applicability of results. A design lifetime of truck
traffic (10 million standard axle loads) is applied over a two-year period of
time. Unlike conventional efforts on public roadways, research at the NCAT Pavement
Test Track is conducted in a private facility where axle loadings are precisely monitored
and environmental effects are identical for every mix. An array of surface
parameters (smoothness, rutting, cracking, etc.) are monitored regularly as truck traffic
accumulates to facilitate objective performance analyses. State DOTs typically
have to wait 5 to 15 years to obtain less reliable results in full-scale field studies on
Sponsors typically fund research on two
or more sections so they can compare life cycle costs of common paving alternatives.
In this manner, they can rationally manage the publics investment in flexible
pavements by choosing mixes that cost less over the life of the structure. For
example, it is unwise to spend less on construction if the cheaper construction
alternative results in a substantially higher life cycle cost. In addition to
comparing alternatives for sponsors, NCAT is responsible for guiding the overall effort in
a direction that will address policy issues for the highway industry as a whole.
The Pavement Test Track is the result of industry and government
committing to work together to improve the quality of flexible pavement performance, thus
maximizing the taxpayers investment in Americas roadway transportation
infrastructure. This facility is expected to clarify the relationship between
methods and performance such that design and construction policy in the future can be
objectively guided by life cycle costs.
