This webinar will cover each of the major categories of geosynthetic materials, discussing their functions and their applications in civil and geotechnical projects. Topics to be covered include: Geotextiles, Geogrids, Geomembranes, Geocells and Geocomposites. For each material, we will review the characteristics that contribute to its engineering functions, and then provide a basic review of how it is used. This session will not include detailed information on design methodologies – it is intended as an introduction for those who may be new to geosynthetics, or a review for those who may not deal with these materials on a regular basis. Future sessions will include more rigorous information on specific applications. This course may serve as one half (1/2) Professional Development Hour.

All pavements eventually wear out but it’s only considered a failure when that happens before they reach their design life. Many causes of pavement failure can be controlled. Having a better understanding of these causes and how to circumvent them can help us improve road performance and reduce life cycle costs. This course may serve as one half (1/2) Professional Development Hour.

In this session, we will review options for addressing unsuitable soils during construction. We’ll start with a discussion of methods for assessing the condition of the subgrade, which is essential to evaluating potential solutions. Then we’ll move on to methods for stabilizing soft soils, including both conventional and innovative approaches. This webinar should prove beneficial for anyone involved in site development and earthwork who needs to make decisions about how to deal with weak and saturated soils which are unsuitable for construction.

In this session, we discuss the proper installation of TriAx Geogrid. We begin the session with the basics, offer guidance on best practices to make installation go smoothly and conclude with a look at some extreme conditions and how to install TriAx when nothing else can do the job nearly as well, or maybe at all.

In this session, we’ll discuss two special applications for Mechanically Stabilized Earth (MSE) walls: temporary walls and pressure relief walls. Temporary walls can be used for a variety of purposes related to construction sequencing and expediency, including temporary access ramps, bridge abutments, and support of earthwork. Pressure relief walls can offer significant savings on structures which have large areas below grade, by providing a more efficient means of containing the earth pressure on the structure than conventional methods, permitting more efficient construction. We’ll discuss the design theory and practical aspects of both applications, and provide project examples.

Pavements, especially on county and municipal roads, rarely complete their life cycle without multiple repairs from numerous trenches and other underground work. It is difficult to restore the structural capacity of the pavement and the integrity of the surface in these localized repairs, resulting in distress and failure under the continuing traffic loading. In this webinar, we will discuss the use of Tensar TriAx Geogrid to improve areas of localized repair, including trench cuts, localized base failure, and lane widenings or extensions. Topics covered will include evaluating distress, trenching through existing pavements which include geogrid, determining the required thickness of repaired sections, and recommended details for repaired areas to improve the structural capacity and reduce failures.

This webinar will discusses natural forces affecting our nation’s shorelines such as storms, coastal processes and sea level rise.
We will then focus on why our attempts to tame our shorelines have often had unexpected or unintended results, and have even at times done more harm than good.
We’ll discuss and compare counter-measure solutions including conventional structures, various hard armor systems and geosynthetic solutions and compare their advantages and disadvantages to help you determine which of these may be right for your project.

This webinar discusses how Tensar TriAx Geogrid and FilterGrid can be used to create and/or improve petrochem and oil & gas sites. We’ll explore how TriAx works to stabilize sites with poor subgrades trafficked by heavily loaded trucks and construction equipment; and, how FilterGrid creates strong construction platforms over wet, silty subgrades, often with CBRs below 0.5. We will also share recent examples from projects that benefited greatly from Tensar’s technology, although some details will be omitted due to existing NDAs. The discussion will be led by Tensar’s Scott Phillips, P.E., who has many years of design experience in the petrochem and oil & gas industries.

In this webinar, we will discuss the use of geosynthetic interlayers to extend the life of asphalt pavements. Topics to be covered include:
The different types of interlayers, and the advantages and disadvantages of each
The mechanisms by which interlayers extend pavement life
Selection of the correct interlayer type based on pavement distress, pavement section, traffic loading, and other factors
Designing with interlayers to improve resistance to asphalt fatigue
Installation guidance

Applicability of different approaches
Advantages and disadvantages of each approach
Cost/benefit analysis
Common misconceptions on this subject, and how they can lead to inefficient designs or even failures
