  • Bases and Subbases for Concrete Pavements

    Credits: 1 PDH

    PDH Course Description:

    This course is based on an FHWA Tech Brief on Bases and Subbases for Concrete Pavements. It provides guidance on the selection and construction of base and subbase layers for concrete pavements.

    This course covers various types of base and subbase layers, including unstabilized base, cement-stabilized base, lean concrete base, asphalt-treated base, and stabilized open-grade drainage layers. It includes best practices for the construction of each type of base and subbase layer and emphasizes the importance of selecting a base type based on the purpose of the base, locally available materials, and cost-effectiveness. Also discussed is the use of recycled materials as a source of aggregate for base and subbase layers and guidance on evaluating cost-effectiveness using life cycle cost analysis.

    Topics:

    • Functions of Base and Subbase Layers
    • Types of Base and Subbase Materials
    • Material Properties for Base and Subbase Layers
    • Selection of Base and Subbase Types
    • Construction of Base and Subbase Layers
    • Performance of Base and Subbase Layers
    • Cost Considerations for Base and Subbase Layers
    • Conclusion and Future Research Directions
