Infrastructure Maintenance and Materials Ongoing Projects

• Developing A Standard Test Method for Measuring Geosynthetic-Soil Resilient Interface Shear - UTC

  Establish specific test protocols to determine parameters pertinent to geosynthetic reinforced pavement design. These testing protocols will be used to establish best practices for conducting cyclic pullout tests such that these protocols can be incorporated into American Society for Testing Materials (ASTM) testing standards.

• 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.

• Validation of Rehab Strategies to Extend the Service Life of Concrete Bridge Decks

  The objective of this research is to investigate the long-term effectiveness of Caltrans’ preservation and rehabilitation strategies for concrete bridge decks. Caltrans currently employs high molecular weight methacrylate (HMWM)-based crack sealing and polyester overlay. This research will also explore the value of Portland cement concrete (PCC) and asphalt concrete (AC) overlays on bridge decks, and identify the appropriate treatment time and frequency for these strategies.

• Feasibility of Reclaimed Asphalt Pavement as Aggregate in Portland Cement Concrete Pavements

  The objective of this project is to develop and characterize an environmentally friendly concrete suitable for transportation-related applications in which a portion of the conventional aggregate has been replaced with reclaimed asphalt pavement.
