The nucleus
of the laboratory is a 50,000-pound capacity test frame, manufactured
by Instron, comprising the most advanced digital technology
system currently available. This closed-loop, servo-hydraulic
machine is capable of providing a wide range of frequencies
and amplitudes (up to a 10-inch stroke), for versatile testing
of a multitude of low-to-medium strength materials, in both
tensile and compressive modes of testing.
Specializing
in dynamic testing, Boudreau Engineering's laboratory operation
is primarily focused upon soil, aggregate, concrete and asphalt
used as pavement materials in road construction. The laboratory
also enables Boudreau Engineering to provide clients with
additional capabilities in the areas of fatigue testing and
analysis services for other materials such as plastics, composites
and metals.
As a complement
to the traditional, full-service geotechnical and construction
materials laboratory (soil, rock, aggregate, concrete, asphalt
and metals), Boudreau Engineering offers the additional, advanced
testing capabilities highlighted below:
