Assessment of Aggregate Sources in Michigan for High Speed Railroad Ballast

Dr. Stan Vitton is leading a project that analyzes acceptable aggregates available in Michigan for railroad ballast on high speed rail lines. The current work on the railroad ballast project involves identification and testing of a select number of aggregates to evaluate whether their characteristics meet ballast specifications. In the spring the project began static and dynamic testing of ballast sources in the Upper Peninsula of Michigan, especially the carbonate aggregates.
