8 am – Noon | Concurrent half-day Short Courses (choose one)
Knowledge for Better Design of Geosynthetic Reinforced MSE Structures
Instructor, Michael Simac, EARTH Improvement Technologies
Better design, specify and analyze reinforced Mechanically-Stabilized Earth (MSE) structures by investigating common problems, interpreting data and schematics, and leveraging project partners to improve planning and performance.
Designing with Geosynthetics – Construction Protocols
Instructor, L. David Suits, LDS Geosynthetic Consulting Services
The course is intended for geotechnical, civil, and environmental engineers, construction contractors, and other personal involved with constructing with geosynthetics. After a brief review of the types of geosynthetics and the applications for geosynthetics in roadways, the proper construction protocols and the importance of following the correct protocols will be presented. The areas that will be discussed include drainage, erosion control, pavement overlay, embankments, and reinforced soil slopes. As good construction depends on good, clear specifications, there will a brief review of geosynthetic specifications. There will also be a presentation on sustainable construction with geosynthetics.
12:15 – 1:30 pm | Lunch – Discussion Panel
Incorporating Geosynthetics in the Enhancement of Transportation Infrastructure in Texas
Panel members TBA
As Congress and the current administration continue seeking ways to fund infrastructure improvements throughout the U.S., states are overcoming challenges to manage tight budgets. Geosynthetics, including stabilization geotextiles, reinforcement geogrids, and pavement interlayers can reduce construction costs and extend the life of transportation infrastructure. Experts in the field of geosynthetics and civil engineering will discuss challenges of infrastructure in Texas, and opportunities to incorporate geosynthetics for cost savings and extended design life.
1:45 – 3:30 pm | Technical Lectures
Use of Geosynthetics in Airport Pavements
Benjamin Mahaffey, P.E., Civil Engineer, FAA
Hear about new research, future goals and updated specifications for geosynthetics in airport pavements by examining FAA studies, newly drafted language in the Advisory Circular 150/5370-10H and proposed pavement testing initiatives.
Capillary and Moisture Control in Roadway Structures using Wicking Geotextiles
Brian Baillie, P.E., Engineering Business Manager, South Central Region, Tencate
Review the effects of capillary rise on foundations and various subgrade soil materials, including new research, current solutions, plus newly available technologies used to minimize the effect of capillary rise on geotechnical foundation systems.
Effect of Differential Settlement on the Performance of the GRS-IBS
Murad Abu-Farsakh, Ph.D., P.E., F.ASCE, Research Professor, LSU/LRTC

8 – 9 am | Morning Plenary
The U.S. Army Corps of Engineers Role in Advancing our Nation’s Infrastructure
Jeb Tingle, P.E., Senior Research Engineer, U.S. Army Engineer Research and Development Center
How do we improve America’s infrastructure? Annual reviews of the nation’s infrastructure describe a deteriorating network with restoration requirements far outpacing agency budgets. This session will outline the role that research and development plays in maximizing the impact of infrastructure projects with limited budgets by:
1. reviewing why “business as usual” is unsustainable,
2. describing the role that research can play in improving infrastructure solutions,
3. demonstrating the value of innovation in infrastructure projects, and
4. outlining a roadmap for implementing new technologies to improve project efficiency.
9:15 – 10:45 am | Panel Discussion – Organized by Geosynthetic Materials Association (GMA)
Geosynthetic Solutions for Levee Infrastructure
Panel members: Doug Brown, P.E., Tensar; John Lostumbo, P.E., Tencate; Michael Bernardi, P.E., Strata; Sven Schröer, HUESKER; TBD, Propex
As aging levee infrastructure is refurbished and rebuilt, geosynthetics are critical to their durability, resiliency, and sustainability. Various types of geosynthetics can provide soil reinforcement, improved drainage and seepage control, consolidation, slope stabilization, erosion control, and other functions for levee construction in innovative ways. Panelists will field questions on the use of specific geosynthetic solutions for various issues and concerns, and provide examples of innovative techniques that led to successful performance.
11 am – Noon | Technical Lectures
Reinforced Soil Slopes
Sachin Mandavkar, Technical Manager, Maccaferri
Examine the advantages of reinforced soil slopes (RSS) as an economical alternative to conventional embankment slopes within limited right-of-way and Mechanically-Stabilized Earth (MSE) walls.
Design and Construction of Geosynthetic Stress Relief Wall for US Bank Stadium
Stephan Gale, PE, D.GE, F.ASCE, Principal Engineer and President, Gale-Tec Engineering, Inc.
Gather insights from the design and construction of a solution that saved the Minnesota Vikings Stadium millions of dollars leveraging geosynthetics to offset poor-quality bedrock.
12:15 – 1:15 pm | Lunch
1:30 – 3:15 pm | Technical Lectures
