n this April/May issue of Geosynthetics magazine, our feature authors
tackle three very different uses of geosynthetics with in-depth examination, testing and even a new design method.
In the introduction to their article, " Modular Geosynthetics
Construction, " E. Silva, T. D. Stark and Duff Simbeck discuss the benefits
of a specific manufacturing process for geomembranes. They write, " This
article focuses on the use of modular construction for geosynthetics. The
same benefits of using modular construction for buildings can be realized with geosynthetics. For example, installation of a factory-fabricated
geomembrane can occur simultaneously with site work, allowing the project
to be completed in as much as one-half of the time required for traditional
field fabrication. "
Pietro Rimoldi and Nicola Brusa break new ground with their article, " Development of a New Design Method for Rockfall Protection
Embankments Reinforced with Geosynthetics. " They note, " The authors
of this article . . . have developed a new analytic approach methodology. . . . The present article introduces the basics of the proposed method,
while the method will be fully presented in future conferences and journals.
The Rimoldi-Brusa method is derived from the Italian standard (UNI
11211-4:2018), so it is based on the resistance capacity of the embankment
to impact, and it allows the designer to estimate uphill block penetration
and downhill extrusion of the geosynthetic-reinforced RPE. "
After outlining in Part 1 of their article in the February/March issue of
Geosynthetics, " Comparative Analysis of the Flow and Filtration Capabilities
of Sediment Retention Devices, " James E. Sprague and C. Joel Sprague lay
out Part 2, noting " the results of historical testing efforts will be presented,
providing a robust and compelling data set, and an in-depth analysis of
the results will be discussed. Products will be defined by product category,
and categories will be compared for general performance. These objective,
data-driven comparisons will help designers, specifiers and regulators
make informed decisions on the appropriate SRD system to use on any
given jobsite. "
Whether the geosynthetics are in a factory-controlled setting, on a
mountainside or stemming erosion control, they rise to the occasion.
