Mineralogical analyses were performed on the Mesabi Select aggregate taken from a stockpile (-1 inch size) at MnROAD comprised of crushed material obtained from the top 25 feet of the 'Lower Cherty' member, or LC-8 bed (LC-6 bed in NRRI study), of the United Taconite mine near Eveleth. The material was utilized in asphalt (cell 32) and concrete pavement (cell 54) constructed at MnROAD's low volume loop.
