Fundamentals of Geosynthetics- Types, Functions, Materials & Selection

Instructor: Kerry Petrasic, P.E., Gannett Fleming

The short course provides a comprehensive overview of geosynthetics. The course is intended for individuals with a desire to explore the use of geosynthetic materials in design and construction applications, and those having a need to gain a broad fundamental knowledge of the various geosynthetic types, materials (synthetic polymers and additives), functions and applications. The course provides a basic definition of geosynthetics, explores the various geosynthetic material types, the synthetic polymers and polymer additives used in manufacturing, strengths and weaknesses of geosynthetic materials, the physical structure of the various types of geosynthetics, functions and applications.

Description and properties are presented for the most common synthetic polymers used in the manufacturing of geosynthetics. Geosynthetic materials discussed include geotextiles, geogrids, geocell, geomembranes and geosynthetic clay lines (GCLs), geocomposites (drainage and paving composites), erosion control/turf reinforcement materials and geofoam. Applications addressed include separation, filtration, drainage, stabilization, reinforcement, load distribution, capillary break, bond breaker, protective layer, lightweight fill, paving interlayers, steep slope facing, compaction aid, and erosion/scour control. The prominent roles of polymer type and material physical structure are emphasized in dictating the performance of geosynthetics for a specific application, and the balancing of often competing needs. Emphasis is placed upon the interdependency of function, material structure and polymer type and formulation, in effective and cost efficient selection of geosynthetics for specific applications. A matrix is presented indicating applicable and desired geosynthetic materials for a wide range of functions and application. The optimal functions and applications for each geosynthetic material are discussed with the supporting rational for their selection. Two detailed examples of material selection are provided illustrating the interdependency of function, material structure and polymer type.

Available industry resources are also briefly covered.

MASW for Geotechnical Seismic Investigation

Instructor: Choon Park, Ph.D.

The short course will cover both theoretical and practical aspects of the MASW method. The morning session will cover most background theories in the field operation for data acquisition and the subsequent dataanalysis steps of dispersion and inversion. The session will also cover the most up-to-date theories and practice trends. The afternoon session will start with an outdoor demonstration (about 1 hour) of field data acquisition by using a typical set of equipment (i.e., 24-channel seismograph, 4.5-Hz geophone receivers on a land streamer, and a 10-lb sledgehammer) at nearby open space, preferably at a parking lot of the venue. The demonstration will collect actual data sets for 1D (Vs30m) evaluation and 2D cross section of the subsurface. It will then be followed by a data-analysis practice session, back in the classroom, using a software package distributed on-site.

Participants will have opportunities to process real data sets included in the software package and collected on-site. The later part of the afternoon session will cover the most recent trend in typical applications. The entire course will proceed with ample time for Q&A and open discussion. Each participant should bring a laptop computer for the data-process practice.

Vertical Barriers for Dams, Levees and Geoenvironmental Applications

Instructors: Dan Ruffing P.E., M.ASCE, and Jeffrey Evans, Ph.D., P.E., D.GE., F.ASCE

Two experienced engineers, one from the construction industry and one from academics, offer attendees a short course on vertical barriers for dams, levees and Geoenvironmental applications. The course offers a balance of theory and practice in such away as to inform attendees of the issues across the spectrum of design, construction, monitoring and performance(short and long term). The short course will first provide an overview of the vertical barriers including a discussion about the primary functions and important performance characteristics.

The primary techniques currently employed will then be presented including an in-depth look into the design and construction methods and important considerations for all stages. The short course will present an overview of common field monitoring practices and procedures, including advantages and limitations of the various available methods. Finally, factors affecting costs for the various techniques along with current cost information will be presented.

Enhanced In-Situ Testing with Emphasis on CPT

Instructor: Paul Mayne Ph.D., P.E.

This one-day seminar on cone penetration testing (CPT) and her sisters (CPTU, SCPT) covers the basic evaluations of soil behavior type, geostratigraphy, and the interpretion of geoparameters, including: unit weight, relative density, effective friction angle of sands and clays, yield stress ratio, modulus, and the use of dissipation tests for assessing the coefficient of consolidation and permeability. The value of shear wave velocity is featured as a fundamental stiffness of the ground. Additional modules cover the evaluation of both flow and cyclic liquefaction from CPT, as well as direct methods for shallow & deep foundations and new developments in penetrometer technology.

Sustainable Engineering: Drivers, Metrics, Tools & Applications

Instructors:Krishna R. Reddy, Professor, University of Illinois, Chicago, IL, USA, Claudio Cameselle, Associate Professor, University of Vigo, Spain, Jeffrey A. Adams, Principal, ENGEO Inc., San Jose, CA, USA

This short course comprehensively covers detailed information about sustainability and resiliency principles and applications in engineering practice, and provides information on how to use scientific tools for sustainability assessment that help engineers select the optimal alternative for each project or activity. It is logically organized around the three pillars of sustainability—the environment, economy, and society. This short course offers numerous ways to help engineers contribute towards global sustainable development while solving some of the grand challenges the world is facing today. The first part of the short course covers the environmental, economic, and social impacts associated with project/product development as well as society as a whole. This is followed by sustainability metrics and assessment tools, which include material flow analysis and material budgets, carbon footprint analyses, life cycle assessments, environmental health risk assessments, and more. Next, an overview of sustainable engineering practices is provided, including sustainable energy engineering, sustainable waste management, and green and sustainable buildings and infrastructure. The short course concludes with a look at how sustainable engineering may be applied to different civil and environmental engineering projects.

Design and Construction with Lightweight Cellular Concrete

Instructors: Binod Tiwari, Ph.D., P.E., F ASCE, Associate Vice President & Professor, California State university, Fullerton, Ryan B. Maw, PE, GE, Principal, Gerhart Cole, Diego Villegas, Vice President of Engineer Fill, Cell-Crete Corporation

Light-weight cellular concrete (LCC) has been extensively used globally in various engineering applications for over 60 years. However, there are limited material properties and design guidance available for using LCC materials in geotechnical applications. This short course will provide engineering designers and construction engineers some essential tools for geotechnical design of embankments and retaining walls as well as current construction practices with LCC. During the day-long short course, we will cover topics such as overall review of the background pertinent to LCC, their formation process, mechanical and physical properties of LCC, current engineering applications of LCC in civil and geotechnical engineering practice, design considerations, and case studies where LCC was successfully implemented in engineered fills and mechanically stabilized LCC walls application.

Half Day Courses

8:00 a.m. – 12:00 p.m.

Design and Monitoring of Leachate Recirculation Systems

Instructor: Milind V Khire, PhD, PE, BCEE, Professor, Civil & Environmental Engineering and Assistant Director of Environment and Construction, UNC Charlotte

There are about 1,500 active municipal solid waste (MSW) landfills in the U.S. Depending on the climate and size of the landfill, these landfills generate 20,000 gallons to 200,000 gallons of leachate every day. A majority of the leachate ends up discharged to wastewater treatment plants (WWTPs). The key concern with this approach is that it is not sustainable. The primary reason being that WWTPs cannot treat all leachate constituents. For example, WWTPs cannot treat PFAS, heavy metals, and elevated ammonia levels. In addition, cost of leachate discharge to WWTPs is on the rise. Hence, managing the leachate within the footprint of an operational landfill and discharging it to WWTPs only during the post-closure period is the most sustainable approach for leachate management. With that being the key motivation of this course, this short course will provide a good overview of the leachate recirculation methods that are in practice, introduce the key design methodologies and sensor-based monitoring of the performance of leachate recirculation in the field. The key topics that will be covered are as follows. 1. Pros and Cons of Leachate Recirculation and estimation of leachate generation rates 2. Design and implementation of leachate recirculation using horizontal trenches, vertical wells, and permeable blankets. 3. Field case studies and data 4. Typical instrumentation to monitor performance of leachate recirculation systems in the field.

1:00 – 5:00 p.m.

Analysis of Seismic CPT Data

Instructor: Gerald Verbeek

When it comes to analyzing seismic CPT data many practitioners still visually identify first arrival times and then assume straight ray paths to calculate the shear wave interval velocities. When they encounter negative relative arrival times (i.e., the first arrival at a greater depth precedes that at a shallower depth) the data is considered unreliable and the fact that seismic waves don't travel in straight lines is ignored. Consequently, the derived results are not necessarily correct. In this course more advanced analysis methods are presented that take into account actual ray paths (based on Fermat's principle), which will allow the attendee to generate more accurate interval velocity profiles.
