the Preservation Group
Experiment at NCAT and MnROAD is in
production for publication in fall 2017.
The multi-page piece summarizes
progress and findings so far from the
experiment. Here's a condensed preview
of what's coming.
Full-scale accelerated pavement testing
has been conducted for predominantly
southern states at the NCAT Pavement
Test Track since 2000. The Minnesota
DOT's Road Research Facility (MnROAD)
has been conducting similar research for
northern states since 1994.
The objective of the preservation group
(PG15) experiment, in which FP2 Inc. and
its allies are an equal funding partner with
DOTs from 15 different states, is to quantify the benefits of pavement preservation on both low volume and high volume
roadways with results that are practical
and implementable in both northern and
southern U.S. climates. Funding is provided through the national Transportation
Pooled Fund, which supports the NCAT
Pavement Test Track (www.pooledfund.
In order to objectively quantify preservation benefits, test sections were built on
local roadways near both facilities. In the
southern half of the experiment, low traffic
test sections were built on Lee [County]
Road 159 (near NCAT in Auburn, Ala.) in
the summer of 2012 and high traffic sections were built on U.S. 280 (near the NCAT
Pavement Test Track in Opelika, Ala.) in
the summer of 2015.
In the northern half of the experiment,
low traffic sections were built on Mille
Lacs County Road 8 and high traffic sections were built on U.S.169 (both about
45 minutes north of MnROAD in Pease,
Minn.) in the summer of 2016. Thinlays,
