State-of-the-art
aggregate/geotechnical research and test facilities are available
to the TMRC researchers at Michigan Tech. Michigan Tech maintains
AASHTO Materials Reference Laboratory (AMRL) accreditation, which
is administered by the National Institute of Standards and Technology
(NIST) for aggregate testing. The aggregate and geotechnical materials
laboratory facilities consist of three laboratories encompassing
over 15,600 square feet of laboratory space.
One
laboratory is an aggregate pilot plant where
different aggregate crushing, grinding and classification equipment
can be used to simulate full-scale production of aggregates and
reclaimed materials. A second facility is an aggregate
preparation laboratory. The final set of facilities consists
of aggregate and soil characterization facilities.
The combined capabilities of the three facilities are detailed below:
