Taconite as a Lower Cost Alternative High Friction Surface Treatment to Calcined Bauxite for Low Volume Roads in Minnesota

This study will evaluate whether Mesabi (taconite) friction aggregate can partially or fully replace calcined bauxite in high friction surface treatment applications by considering appropriate treatment installation alternatives, including but not limited to: (1) Various adhesion methods, such as epoxy, asphalt binder, and micro surfacing; (2) Varying blends of Mesabi friction aggregate and calcined bauxite including 100% Mesabi friction aggregate and 100% calcined bauxite (for comparison); and (3) Appropriate aggregate gradation.
