A new machine at the U of M Duluth (UMD) will help pavement researchers test the quality of asphalt mixtures and determine how well they hold up against wear and tear.
CTS affiliated researcher Manik Barman in UMD’s Department of Civil Engineering received a 2016 Research Infrastructure Investment Program award from the U of M’s Office of the Vice President for Research to purchase the new machine—an Asphalt Mixture Performance Tester (AMPT).
The AMPT can characterize the performance of asphalt mixtures against typical pavement distresses. The machine can conduct a number of asphalt mixture performance tests with the same equipment, including fatigue tests on new- or recycled- asphalt mixtures, resistance tests against rutting, and stiffness tests.
Researchers will be able to use the AMPT to conduct projects funded by the Minnesota Department of Transportation, Minnesota Local Road Research Board, and Federal Highway Administration, including research focused on sustainable asphalt materials.
Barman’s proposal was one of 11 selected for a Research Infrastructure Investment Program award this year. The awards are designed to help maintain the robust, state-of-the art equipment key to propelling research and innovation at the U.
