Infrastructure Maintenance and Materials Completed Projects

• Use of Fly Ash Concrete with Recycled Glass Aggregate in Commercial Construction

  The objective of this project is to facilitate the use of innovative fly ash based concretes produced with pulverized recycled glass as the aggregate in a variety of applications on a green building project in Missoula, MT.

• 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.

• Axial Capacity of Piles Supported On Intermediate Geomaterials: An MPART Project

  To develop empirically based guidelines for the analysis and design of piles driven into intermediate geomaterials.

• Numerical Modeling and Design Development of Geosynthetic Reinforced Flexible Pavements

  The objective of this project is to develop a numerical model (finite element model) of a geosynthetic reinforced flexible pavement where the geosynthetic is located in the base aggregate.

• Preventative Maintenance Treatments: A Synthesis of Highway Practice

  Identify existing and emerging technologies that could be used to enhance or replace current pavement maintenance approaches used by the Montana Department of Transportation.

• Measurement and Evaluation of Subgrade Soil Parameters: Phase 1 - Synthesis of Literature

  The objective of this project is to conduct a comprehensive literature review of the state of the practice pertaining to testing and evaluation of subgrade soils.

• Compressibility and Heave Characteristics of Subgrade Soils Exposed to Freeze/Thaw Conditions

  The primary objectives of this research are to evaluate heave and thaw-weakening aspects of soils subjected to freezing conditions, and to develop improved correlations for estimating compressibility moduli of subgrade soils typical to Montana and the inter-mountain west.

• Geosynthetic Reinforcement of the Base Course Layer of Flexible Pavements

  To provide a design methodology for use by pavement engineers for the design of flexible pavements using suitable geosynthetics as a reinforcement member contained in the base course layer.

• Synthesis of Warm Mix Asphalt Paving Strategies for use in Montana Highway Construction

  The objective of this research project is to synthesize the latest research on warm mix asphalt paving technologies and provide the Montana Department of Transportation with implementation recommendations.

• Geosynthetic Pullout Behavior under Small Displacements

  investigate the pullout behavior of several geosynthetic materials embedded in soils to provide interaction properties for a finite element model. The finite element modeling, which is not part of this project, is based on a large-scale simulation of a geosynthetic reinforced pavement structure.
