This interim report documents the field performance of nine concrete pavement projects that incorporate recycled concrete aggregate (RCA) in the construction of the pavement. Multiple sections were evaluated on many of the nine projects, due to perceived differences in performance levels or variations in pavement design (such as the use of virgin a

Electrochemical impedance spectroscopy (EIS) measurements were carried out on steel bars embedded in concrete blocks that were immersed in aqueous solutions of commercial deicing salts, many of which had corrosion inhibitors added. The effectiveness of the inhibitors was assessed by monitoring the evolution of the EIS results for a period of 11 mon

Stone Matrix Asphalt (SMA) has been used successfully in Europe for over 20years to provide better rutting resistance and to resist studded tire wear.Since 1991, the use of SMA has increased steadily in the United States. Atpresent, some states routinely use SMA even though a standard mixture designprocedure is not available. A mixture design proce

Several regional coalitions are developing multi-year programs for commercial vehicle operations (CVO). This program will include the application of Intelligent Transportation Systems (ITS) technologies and services. This report identifies the institutional barriers that are likely to impede the development of ITS/CVO programs, and recommends strat

The travel modeling process has undergone many changes in the past few years in order to evaluate more complex policy actions resulting from legislation such as Intermodal Surface Transportation Efficiency Act and the Clean Air Act. As travel models have become more complex, so have the procedures needed to validate them. Often there is a tradeoff

The Driver/Carrier project was organized in two phases. The goal of this report is to address the three goals stated in the previous section. This report will discuss the overall findings and conclusions of the project research and analysis. The report will also suggest recommendations for moving forward. The various methods used for the research a
