Infrastructure Maintenance and Materials Ongoing Projects

• Relative Operational Performance of Geosynthetics Used as Subgrade Stabilization

  The main objective of this project is to determine material properties of geosynthetics that affect in-field performance of geosynthetics used for subgrade stabilization, so that DOT personnel can objectively and confidently specify appropriate geosynthetics based on material properties and cost for a specific situation, while also allowing competition from different manufacturers.

• A Corrosion Monitoring System for Existing Reinforced Concrete Structures

  The objective of this research is to develop a deployable, prototype corrosion sensing system for existing ODOT reinforced concrete structures.

• Determination of Material Properties and Deflection Behavior for Contemporary Prestressed Beam Design

  The primary goal of this project is to provide guidance specific to Montana design and construction practices that will result in more efficient prestress concrete bridge structures.

• Cost-Effective and Sustainable Road Slope Stabilization and Erosion Control

  The objective of this synthesis is to compile available knowledge and useful, cost-effective practices on roadway slope stabilization and erosion control.

• Evaluation of Deep Patch Landslide Mitigation Design Methodology

  The purpose of this project is to evaluate and improve current FHWA Office of Federal Lands Highway (FLH) and US Forest Service (USFS) deep patch design and construction methods.

• Development of a Cold Region Rural Transportation Research Test Bed in Lewistown, Montana

  To improve transportation maintenance, operations and safety with cold-regions research through the collaboration of academia, industry and government.

• Steel Pile Cap/Concrete Pile Cap Bridge Support Systems

  The objective of this project is to conduct physical testing of MDT’s new steel pipe pile to concrete pile cap connection design method.

• Geosynthetic Biaxial Testing Machine Design and Protocol Development

  The objective of this project is to design a biaxial tension testing machine and develop testing protocol to measure Poisson’s ratio of various geosynthetics.

• Evaluation of a New Arch Bridge Technology for Short Spans

  The objective of this research is to conduct a review of the Bridge-in-a-Backpack system - a new construction technology for a corrosion-resistant arch bridge - and other traditional crossing systems that may be used in Montana, to determine where they can be applied with maximum efficacy.

• Effect of Cold Temperature on Shear Strength and Consolidation Properties of Deep Water Soft Marine Clays

  The objective of this project is to examine the effect of cold temperature on laboratory strength and consolidation properties of soft marine clay.
