Geosynthetics October/November 2020 - Geosynthetics Conf. Brochure 5

Short Courses
Geosynthetics Conference offers six half-day Short Courses on Sunday, Feb. 21,
2021. These in-depth courses feature detailed instruction in a small group setting. All
courses provide four pdh's and are included with full registrations at no extra cost.
AASHTO 2020: Three Acceptable Design Methods of
Geosynthetic-Reinforced Walls
Dov Leshchinsky, University of Delaware and ADAMA Engineering; Daniel Alzamora,
FHWA Resource Center

Details of the three, basically unrelated methods, for the design of geosynthetic-reinforced
walls allowed in AASHTO 2020. Discussed are the Simplified Stiffness Method, the Limit
Equilibrium Method, and the Simplified AASHTO Method. While the main focus will
be on internal stability, aspects such as complex geometries, surcharge loads, external
stability and seismic design will be discussed as well. Instructive examples will be used to
demonstrate the fine points of each method while showing the differences in the design
outcomes. To expand the number of comparative cases, both programs MSEW+ and
ReSSA+ will be used. Reinforced slopes will also be briefly covered.

Construction on Soft Soil using Geosynthetics
Lilma Schimmel, HUESKER Inc; Alex Potter-Weight, Menard USA

Learn about the use of geosynthetics to address the challenges of construction on poor
soil conditions. Commonly used and innovative techniques will be discussed at an
introductory level, including Geosynthetic Encased Columns (GECs), Prefabricated
Vertical Drains (PVDs), High Strength Basal Reinforcement and Load Transfer Platforms.
Technical information about specification parameters and design using geosynthetics will
also be introduced.

Designing for a Zero-Leak Containment Facility
Abigail Gilson MS, PE, TRI Environmental; Jeff Blum, Weaver Consultants Group;
Richard Brachman PE, Queens University

The old adage that "all liners leak" does not have to be a foregone conclusion. All leaks
in lining systems have a direct cause including accidents, installation issues, poor
craftsmanship, inadequate material testing, and poor design decisions. A holistic
approach to leakage is taken in this course to address both short-term and long-term
sources of leakage. Using state-of-the-art Electrical Leak Location (ELL) technologies,
leaks can be remedied before a containment facility is put into service. Employing best
practices for Construction Quality Assurance (CQA) can eliminate leaks that develop over
time due to poor installation practices. Performing proper material testing based on the
most recent research on stress-cracking will significantly increase the service-life of the
facility. In short, the reduction or even elimination of leakage starts in the design phase
with good project specifications.

Fundamentals of Geosynthetics-
Types, Functions, Selection and Performance
Kerry Petrasic, Gannett Fleming

Hear an overview of geosynthetics, and is intended for individuals with a desire to explore
the use of geosynthetic materials in design and construction applications, having a need
to gain broad fundamental knowledge of the various geosynthetic types, materials and
applications. The course provides a basic definition of geosynthetics, explores the various
material types and applications. Geosynthetic materials presented and discussed include
geotextile, geogrids, geocell, geomembranes and geofoam. Importance is placed upon
desired function(s) in the selection of material class and type. The prominent roles that
polymer type and material physical structure is emphasized in the successful selection
and desired performance of geosynthetics for a specific application, and the balancing
of often competing needs. Versions of this course have previously been presented at the
Pennsylvania Department of Transportation's "Transportation Management Training
Workshop - TMTW" and the ASCE Central Pennsylvania Geotechnical Conference.
