Texas Contractor Upgrades Performance
lurry seal and micro surfacing
contractor Viking Construction
Inc. is seeing productivity
improvements via acquisition of
new high-performance slurry and microsurfacing pavers.
Founded in 1992, Viking was originally a
division of paving equipment manufacturer
Scan Road Inc. The company was not only a
paving contractor, but it also demonstrated
Scan Road equipment to potential customers and provided Scan Road with a method
for field-testing new equipment designs.
In 2002, FP2 Inc. board member Barry
Dunn purchased Viking Construction after
Scan Road exited the construction equipment industry. Today, Viking operates out of
Georgetown, Tex., and contracts throughout the state for city, county and Texas
Department of Transportation (TxDOT)
slurry seal and micro-surfacing projects.
It's not surprising that Viking
Construction's paving arsenal has historically been composed of Scan Road
machines. With 10 full-time and 35-40
seasonal employees running Viking's
eight HD-10s and one CRM-500 continuous machine, the company's annual
paving season spans mid-March through
"We typically do about 30 large and
small slurry seal and micro-surfacing jobs
each season," says Dan Welsh, Viking
Construction's project manager. "Our city
and county jobs are both slurry seal and
micro surfacing, while our DOT jobs are all
micro surfacing. DOT work comprises a little
less than half of our projects."
In late 2015, Viking Construction was
ready to upgrade its fleet. In January
2016, management acquired an M1E
self-propelled, full-size, continuous slurry
seal and micro-surfacing paver manufactured
by FP2 corporate sponsor Bergkamp Inc.
The M1E boost performance by reducing
the number of construction joints on a job
by receiving a constant supply of material
as the machine is working. Welsh says
Viking's decision to purchase the unit was
based on a couple of factors.
"I was familiar with Bergkamp's
machines from working with them for a
prior employer, and I knew their quality
was top notch," Welsh said. "As we did
our research, we decided the M1E was
the obvious choice for a state-of-the-art
paver. It is a well-put-together machine.
We could not find an equal comparison
model from any other manufacturer for a

Viking chose to use the paver exclusively for its TxDOT highway projects. For
the crew members who began to operate the machine, the major difference
between the existing pavers and the new
unit is that all major component clutches,
chains and sprockets that are standard
on most pavers have been replaced on
the M1E with direct-drive hydraulics that
are controlled by Bergkamp's advanced
onboard EMCAD (Electronic Mix Control
And Diagnostic) system.
Also, direct-drive hydraulics reduce the
number of wear parts and maintenance
points on the machine, while EMCAD simplifies calibration and allows the operator
to control production with simple adjustments. The driver is free to progress at an
optimized rate of speed, ensuring faster
"Our crew members were reluctant at
first to use the M1E and EMCAD," Welsh
said. "This is typical among contractors.
Employees are comfortable with the way
they have always operated. If they're not
familiar with automated systems, they're
skeptical-they think it will make their jobs
EMCAD manages power inputs and
electronically controls material outputs to
maintain the desired mix design, helping to
reduce calibration time by up to two-thirds.
Standard on the M1E, the computerized
monitoring system provides information in
real time regarding the percentage of each
micro-surfacing mix ingredient that goes
onto the roadway, and the operator can
instantly make changes to output levels.
Welsh said some of TxDOT's specifications require computer calibration, adding
that engineers and inspectors have more
confidence in projects that are managed by
an automated system because a computer
can back up information through reports.
"The difference is that you can retrofit a
computer onto pretty much any paving
machine, but it won't be as accurate or
easy to use as the EMCAD is on our M1E,"
