Minnesota Taconite as a Microwave-Absorbing Road Aggregate Material for Deicing and Pothole Patching Applications

摘要: This report presents modeling of temperature profiles for application microwaves to pothole patching and roadway deicing. Values key parameters are estimated presented asphalt-aggregate composites containing varying magnetite content (compacted with voids), ice, water. The are: microwave absorption coefficient at 2.45 GHz, density, heat capacity, thermal conductivity. summarizes the work authors were able complete, including a large number equations characterizing an extensive list references. natural in taconite is outstanding absorber. Consequently, when truck-mounted generator driven over ice-covered constructed crushed as aggregate, should pass through ice be absorbed road-ice interface, allowing easily detached scraped away. energy-efficient process only non-chemical method deicing practical many miles roadway. Adoption this could lead significant demand aggregate. same equipment used year-round applications, energy generate just required amount hot mix on-site permanent repairs.
