Purpose and Background

Coal combustion products provide significant cost savings and enhanced performance in geotechnical applications. Simultaneously they contribute to sustainable construction. This one hour webinar will discuss old and new applications in geotechnical construction for achieving sustainable outcomes.

It will draw from the research and experience of the leaders of the Recycled Materials Resource Center and the literature.

Topics to be covered include:

• Widely used CCPs in geotechnical applications: fly ash and bottom ash
• Types and attributes of fly ashes in relation to geotechnical applications
• Pavement applications: subgrade stabilization, base/sub-base stabilization, subbase replacement with bottom ash
• Structural fill and embankment applications
• Geotechnical design
• Leaching characteristics
• Regulations

Civil and environmental engineers need to consider the life cycle impacts of earthen construction (highways, airfields, levees, dams, etc.) and select materials and methods with these considerations in mind. Coal combustion products solve problems in geotechnical applications with enhanced performance and often lower cost while contributing to sustainable construction.

Learning Outcomes

You will learn about types of coal combustion products, their characteristics, appropriate applications for them and available design properties. You will be introduced to quantitative rating of alternatives relative to life cycle impacts and costs.

Webinar Benefits

• Learn latest applications and methods for using coal combustion products in pavement
