on the crew, Webster said. "If the paver
slows down, the application slows down,"
he said. "It's easy to use."
Once the emulsion is placed, and asphalt
compacted, traffic can be allowed on the
pavement within minutes. "You can let traffic on the UTACS very quickly, it's not a very
'tender' mix," he said.
UTBO ON HIGH-VOLUME HIGHWAY
A pavement preservation project utilizing an UTBO on U.S. 3 in Massachusetts
would be considered significant based on
its size alone, with nearly 1 million sq. yd.
of mainline paving, and over 400,000 sq.
yd. of preservation on the shoulders and
breakdown lanes.
Completed in fall 2015, the project
involved a section of U.S. 3 north and
south from Burlington, Mass., to the New
Hampshire state line at Tyngsborough,
Mass. This 20.6-mile stretch of road is one
of the main routes between Boston and
New Hampshire, with average daily traffic
counts of approximately 100,000 vpd. The
route consists of six total travel lanes (three
northbound and three southbound), as well
as high-speed shoulders and breakdown
lanes in each direction.
As part of the implementation of R26,
MassDOT was selected as a lead adopter
state, with U.S. 3 as a showcase project for
SHRP2-R26, Guidelines for the Preservation
of High-Traffic-Volume Roads.
The contract for the project, awarded
to Brox Industries, Inc. of Dracut, Mass.,
involved a comprehensive scope of work,
including significant pavement repairs and
surface preparation, placement of several
types of preservation treatments, replacement of pavement markings using multiple

methods, and traffic control and safety
management throughout the entire project.
"The project also included a ride specification, making it the first ultrathin bonded
overlay project in the region to include this
requirement," said Ed Naras, pavement
management engineer, MassDOT Highway
Division, Boston.
The mainline paving of the highway
was completed utilizing an UTBO which
involved placement of a heavy application (0.18 to 0.25 gal. per sq. yd.) of polymer emulsion bond coat, immediately

followed by a 5/8 to 3/4-in. gap-graded
hot mix overlay.
"This process seals the existing surface and provides a superior bond to the
hot mix overlay," Naras said. On the U.S.
3 project, the road was split into three
approximately even length sections that
were each treated with a different type
of UTBO. These included sections with
a PG 64-28 binder (control section), PG
64V-28 binder (polymer modified section),
and ASTM D6114 asphalt rubber binder
(recycled material section).

How do you resurface an aging
road, protect the environment,
plus save time and money?

Hot-in-Place Recycling is not only a very green process
that reduces the carbon footprint by 28% versus mill &
overlay, it also reduces congestion and user delays with
far less trucking required.
