n Civil Engineering = Siviele Ingenieurswese - Practical guidance related to geosynthetic interface shear and frictional performance : environmental engineering

Geosynthetic materials are extremely useful and should be a common part of every geotechnical engineer's repertoire, as these materials provide cost savings, simpler construction and greater durability than traditional materials in most cases. How geosynthetics are utilised, particularly relative to their interface interaction with one another and the soils that they are in contact with, is a critical issue in nearly every installation where they are used. Noteworthy science has been undertaken and applied to this issue. Despite these efforts, however, there can be significant confusion on how the measurement and specification of interface friction and direct shear performance should be undertaken, what the construction requirements might be and what specific variables are most critical. This article presents a simple plan for this situation, and more importantly, provides additional resources and references on how to address problematic areas.
