Breaking News on Geosynthetic Reinforcement
HUESKER introduces Basetrac® as the new brand for base reinforcement
The HUESKER Group has restructured its base reinforcement products with immediate effect and will now market them under the Basetrac® brand.
The established products Fortrac® (biaxial), Fornit®, Base, Duogrid®, Comtrac®, Sefitec® and HaTe® have been brought together to form the Basetrac product family.

Prof. Richard Bathurst presents “Lesson Learned from Full-scale Model MSE Wall Tests at RMC”

Presentation Abstract:
A long-term research program was carried out at the Royal Military College of Canada (RMC) between 1998 and 2011 with the objective to gather quantitative data on the behavior of MSE walls under carefully controlled (laboratory) conditions. The research program was funded by a consortium of 12 USA Departments of Transportation together with Canadian funding agencies. Fourteen heavily instrumented 3.6 m-high, full-scale reinforced soil walls were constructed with geogrid and welded wire reinforcement layers. Instrumentation included strain gauges and extensometers attached to reinforcement layers, connection load cells, horizontal and vertical toe load cells, earth pressure cells and displacement measuring devices at the wall face and at the backfill surface. For the hard-face walls more than 300 separate instruments were sampled simultaneously during construction and post-construction. Eleven walls were constructed with the same sand backfill material and were uniform surcharge loaded in stages to load levels well beyond working stress levels. Each wall was designed to isolate the influence of one of the following factors on wall performance: wall facing type, wall batter angle, reinforcement type, stiffness and spacing (number of layers). This talk describes the experimental design, examples of measured data, how the data have been used to verify numerical models and to guide the development of reinforcement stiffness-based design methods for internal stability design of MSE wall systems.
Training Lecture: Geosynthetic Reinforced Embankments on Soft Foundations (Monday, March 13: 2 – 3:30pm)
“Soil reinforcement with geosynthetics is often the economical solution, and some projects cannot be constructed without geosynthetics.”
Instructor: Robert D. Holtz, University of Washington
The design and construction of embankments on very soft foundations is one of most challenging geotechnical problems.
Without some type of foundation soil improvement, failures are common especially on very soft sites.
Soil reinforcement with geosynthetics is often the economical solution, and some projects cannot be constructed without geosynthetics.
The course begins with a brief overview of conventional treatments for soft ground construction.
Some early case histories, mostly failures, are described that provided valuable design lessons and concepts that we use today.
Then analysis and design procedures are outlined, along with selection of the required properties for the geosynthetic reinforcement and embankment soils.
Sample specifications, cost considerations, inspections are also described.
Because proper construction is so critically important for success, a detailed discussion of construction procedures completes the course.
