WTI research is prominently featured in the new issue of Solutions, the research newsletter of the Montana Department of Transportation.  Three recently completed projects are profiled in feature articles:

• “Prefabricated Steel Truss/Bridge Deck Systems.” This study was a WTI and MSU Civil Engineering project led by Damon Fick, Tyler Kuehl, Michael Berry, and Jerry Stephens. It evaluated a prototype of a welded steel truss constructed with an integral concrete deck, which has been proposed as a potential alternative for accelerated bridge construction (ABC) projects in Montana. Steel truss bridges are relatively light weight compared with plate girder systems, which makes them a desirable alternative for both material savings and constructability. See the WTI website for more information.
• “Evaluation of Effectiveness and Cost-Benefits of Woolen Roadside Reclamation Products.” This research project developed three types of products for study: woolen erosion control blankets (ECBs), wool incorporated into wood fiber compost, and wool incorporated into silt fence. The project, supported by Montana Department of Transportation (MDT) and the Center for Environmentally Sustainable Transportation in Cold Climates, compared the wool products’ performance to roadside reclamation products commonly used for revegetating cut slopes. Rob Ament (P.I.) and Eli Cuelho served on the research team. Additional information is available on the WTI website.
• “Feasibility of Non-Proprietary Ultra-High Performance Concrete (UHPC) for Use in Highway Bridges in Montana.” Ultra-high performance concrete (UHPC) has mechanical and durability properties that far exceed those of conventional concrete. However, using UHPC in conventional concrete applications has been cost prohibitive, costing 20 times that of conventional concrete. The overall objective of the Phase I research was to develop and characterize economical non-proprietary UHPC mixes made with materials readily available in Montana. The research was led by Michael Berry. Additional project information is available on the WTI website.
