This webinar was co-sponsored by ASCE's Geo-Institute (G-I) and ASCE Continuing Education

Instructor:  Tuncer B. Edil, Ph.D, P.E., DGE

Course Length: 1 Hour

Purpose and Background

Engineers involved in civil and geotechnical construction (highways, airfields, embankments, levees, dams, etc.) that are interested in sustainability need to know how the materials and methods they use affect the engineering life cycle. Recycled materials can be used to create longer lasting infrastructure that requires less energy to construct and maintain and has a lower carbon footprint. Both public and private owners are increasingly considering these green construction principles in design.

Tire derived aggregate show unique properties that can solve difficult problems in geotechnical and geoenvironmental applications. Tire Derived Aggregates (TDA) provide significant cost savings and enhanced performance in geotechnical applications where lightweight fill material, drainage material, and reactive layers for contaminant sorption are required. Simultaneously they contribute to sustainable construction. Drawing from case histories where TDA has been used in construction, this webinar will discuss TDA applications in geotechnical construction for achieving sustainable outcomes. You will learn about the physical and chemical characteristics of TDA, appropriate applications for TDA, design properties and methods, and use.

Learning Outcomes and Benefits

Upon completion of this course, you will be able to:

• Recognize the latest developments for using TDA in civil, geotechnical, and environmental applications
• Examine how TDA is used in design
• Explore new technical solutions to generate better construction and long-term performance
• Become more competitive by increasing competency in "green" and sustainable design
• Apply quantitative methods for civil, geotechnical, and environmental engineering design with TDA
• Determine how to assess potential environmental impacts of TDA and unintended consequences
• Become better tuned with the ASCE Code of Ethics relative to "sustainability"

Assessment of Learning Outcomes

Students' achievement of the learning outcomes will be assessed via a short post-assessment (true-false, multiple choice and fill in the blank questions).

Intended Audience

Construction engineers, materials engineers, geotechnical engineers, highway engineers, environmental engineers, government engineers, highway planners, regulators and recyclers will benefit from this webinar.

Seminar Outline

• Characteristics of TDA: size, shape
• TDA applications: lightweight fill, leachate collection and drainage layers, reactive layers to treat waste liquids, sound/ vibration barriers, artificial turf
• Geotechnical properties of TDA and TDS-soil blends: shear strength, interactions with geosynthetics, compressibility, hydraulic conductivity
• Leaching characteristics and sorptive characteristics
• Case histories

How to Earn your CEUs/PDHs and Receive Your Certificate of Completion

To receive your certificate of completion, you will need to complete a short on-line post-test and receive a passing score of 70% or higher within 1 year of purchasing the course.

How do I convert CEUs to PDHs?

1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
