Aggregate and Geotechnical Materials Research

   Analyzing the rut test results for wear on asphalt and concrete.

Michigan Tech is home to the Aggregate Research Center, which is the first such agency in the country funded by the federal government.

The center has some of the finest facilities anywhere for evaluating, processing, and characterizing aggregates and geotechnical materials.

Aggregate and Geotechnical Facilities
The Aggregate Processing Plant simulates full-scale production of aggregates and reclaimed materials; it can sort 3,000 pounds of coarse aggregate in an hour.

The Aggregate Preparation and Classification Laboratory separates, crushes, mills, and analyzes aggregates for gradation and proportion.

The Geotechnical Research Facilities perform advanced material characterization.

 

Our research
We work with both traditional and new materials for the aggregate component in concrete, including

  • blast furnace slag
  • carbon fibers
  • crumb rubber
  • polymers
  • ultra-thin overlays

We also look at how pavements interact with the environment—from freeze-thaw durability to building roads in wetlands. A sampling of our work with aggregate

  • bituminous pavement surface characteristics and their effects on friction properties
  • mineral characterization and cataloging of quarried aggregate sources used in Michigan highway construction
  • ground surface temperature and climate change from borehole temperature data
  • particle-size analysis of soils using laser and x-ray diffraction technology


Since 1885, Michigan Technological University has offered educational excellence in beautiful Upper Michigan.
Our students create the future in computing, engineering, the sciences, business, environmental studies, technology, and communications.
