President Mario Huerta’s operations also include the Astec Mobile Screens’ ProSizer and Telsmith’s crushing and classifying equipment.
came to the Double Barrel Green ®
System and New Generation
Storage Silos:
“The Green System added to the
Double Barrel drum mixer allows
me to reduce fuel consumption
and increase production, “ said
Huertas. “The warm mix asphalt
does not need the addition of
expensive commercial additives;
using water with the mix along
with the liquid asphalt cement is
all that is needed.”
Since 1986, Mr. Huertas has
been learning more about the
advantages of mix storage and
became an admirer of the silos
for asphalt plants.
When asked specifically about
the storage silos, Mr. Huertas
continued:
“We are able to store mix in
the Astec New Generation HMA
storage silo for four days without
the loss of mix quality,” said
Huertas. By keeping the silo full,
the plant is always ready to meet
customer demand; equipment
efficiency is maximized and
material waste is reduced.
In storage mode, the silos are
completely sealed at the top
and the bottom to prevent
oxidation. Huertas explained,
“I have become convinced that
silos allow you to increase daily
According to President Mario
Huertas, the Astec plant was
the best solution to guarantee
a permanent and ready supply
of hot mix while meeting the
contractor’s specifications.
production with a substantial
reduction in operational costs for
the mix made on the previous
day, which allows a better and
more efficient use of human
resources to mix transport trucks
to feed the road works.”
Partnership with Astec
To date, M.H.C. has three
Telsmith aggregate classifiers
(Model 2561T), two impact
crushers (Model FT4240), one
vertical axis impact crusher 2500,
one Astec Mobile Screens model
PTSC (Model 3618Vm), and one
ProSizer (Model 2612V).
“The relationship with Astec is
a partnership that goes beyond
basic customer service,”
acclaimed Huertas. “The Astec
group knows its products; knows
how to relate the technologies to
my applications; and knows how
to provide excellence in customer
service—this is evident through
all Astec divisions and the people
that represent the company,
including our Colombia Astec
Agent, Rodriguez and Londono
S.A.”
Meeting the standards required
by M.H.C.’s customers is not a
problem according to Huertas,
who said Astec listened to
his technical and business
suggestions, thus allowing him
to purchase equipment to provide
better production, a reduced
maintenance cost, and a better
mix quality to his operations.
“In terms of service, Astec has
been very effective, receptive,
timely, and very experienced,”
said Mr. Huertas. “With the
conditions in Colombia, we need
a good response on parts for
routine maintenance.”
Mr. Huertas continued, “Astec has
maintained the added value with
its customers through its postsale
relationship between local
agents and end customers.”
Future Projects
Huertas is waiting for the
Colombian government to
push forward with the road
infrastructure projects which
consider bridges, tunnels,
hydroelectric power dams, as well
as all other infrastructure that
was damaged by the recent heavy
rains at the end of 2010 and early
2011.
“I am sure that once the tenders
are laid out with specifications
and work requirements, we are
going to be able to participate
with the help from Astec by
analyzing the most efficient
and practical equipment to
do the job,” affirmed Mr.
Huertas.
