Freight Performance Measures: Approach Analysis, B. Starr Mcmullen, Christopher M. Monsere

Civil and Environmental Engineering Faculty Publications and Presentations

This report reviews the existing state of the art and also the state of the practice of freight performance measurement. Most performance measures at the state level have aimed at evaluating highway or transit infrastructure performance with an emphasis on passenger transportation. Freight performance measurement ultimately requires evaluation of performance of the entire freight transportation system, which includes highways, waterways, rail, air, and modal connections. This requires considerable expansion of thinking beyond the traditional focus of state Departments of Transportation (DOTs) on highway performance.

This project builds upon past and current work in the area of freight performance measurement and …

Instrumentation For Mechanistic Design Implementation, Todd Scholz

TREC Final Reports

The Oregon Department of Transportation (ODOT) Pavement Services Unit is in the process of implementing a new pavement design procedure being developed under the sponsorship of the American Association of State Highway and Transportation Officials. Fatigue cracking is a key distress mechanism that is predicted as part of the overall process using a theoretical model calibrated to empirical data. Tensile strain at the underside of the hot-mix asphalt pavement layers induced by truck axle loads is, in turn, a key input into the fatigue cracking model. In the new design procedure tensile strain is predicted utilizing a layered elastic analysis …
