The objective of this report is to provide a benchmark for elevator managers in assessing performance, and supply a source for recognizing trends in the characteristics of North Dakota elevators. This research investigates moisture susceptibility of asphalt mixes; evaluates the effect of various numbers of freeze-thaw cycles on the mechanical properties of asphalt and determines if the Georgia Loaded Wheel Tester can be used to test for moisture induced damage. This report represents a continuation of analysis concerned with the patterns and methods of distributing grains and oilseeds from North Dakota. This report examines the potential role of a new form of transportation intermodal truck-rail container transportation in the state's expanding manufacturing and value-added agricultural base. It explores the general advantages of intermodal container transportation, examines factors that make intermodal...
