Abstract (sommario):

Geosynthetic engineering has made significant advances during the past decade in the areas of manufacturing and practical applications. As a result, geosynthetics have become essential materials that facilitate construction, better improve short- and long-term performance, and reduce long-term maintenance costs in routine civil engineering projects. Geosynthetics are also being recognized as fundamental to sustainable infrastructure development as they reduce the carbon footprint generated by infrastructure development by minimizing the use of natural construction materials.

Abstract (sommario):

The time at which a geosynthetic’s performance falls below established functional thresholds is known as the geosynthetic’s functional longevity. As opposed to “durability” which commonly refers to an individual exposure environment such as UV exposure or a specific chemical exposure preceded and followed by an index test to quantify physical changes, functional longevity is the result of the synergistic effects of one or more exposure environments happening simultaneously or sequentially preceded and followed by a performance test. Therefore, functional longevity is characterized by a “suite”

Abstract (sommario):

Abstract This study compares how geosynthetics behave under load, under strain, and over time when subjected to confined tensile tests in soil, employing two commonly used mechanisms in research. One test type simulates a reinforced layer, where tensile loads are indirectly applied to the geosynthetic via stresses transferred from the soil. In contrast, the other test applies tensile loads directly to the geosynthetic material using clamps while under soil confinement. The objective is to elucidate how these testing mechanisms might yield differing in-soil tensile characteristics for different

Abstract (sommario):

In traditional analyses of flexible pavements the linear elastic material behavior is assumed for pavement materials. However, pavement materials do not behave as linear elastic materials. They can be better modeled by using elasto-plastic constitutive relationships. The consequences of the assumption of linear elasticity in the prediction of the behavior of geosynthetic-reinforced flexible pavements are presented. The effect of the stiffness of geosynthetic reinforcements on pavement behavior is also studied. The behavior of a geosynthetic-reinforced flexible pavement is analyzed by the finit

Abstract (sommario):

Geosynthetics are commonly considered to provide restoring forces against sliding during overall slope stability analyses. Where a slipping surface intersects a geosynthetic layer, the geosynthetic layer produces a reaction force either in the opposite direction of sliding, in the direction of the geosynthetic alignment, or in some intermediate direction. The provision of geosynthetic reinforcements typically increases the factor of safety in limit equilibrium against overall sliding in the design of a mechanically stabilized earth (MSE) wall, and for this reason has become popular among pract

Among the various types of polymeric materials, geosynthetics deserve special attention. A geosynthetic is a product made from synthetic polymers that is embedded in soils for various purposes. There are some basic functions of geosynthetics, namely, erosion control, filtration, drainage, separation, reinforcement, containment, barrier, and protection. Geosynthetics for erosion control are very effective in preventing or limiting soil loss by water erosion on slopes or river/channel banks.

Abstract (sommario):

The governing mechanism associated with the stabilization of unbound aggregate layers in pavements is lateral restraint. Reproducing this mechanism in the laboratory maybe challenging because, while the original loading source is cyclic (traffic), lateral restraint develops through interlocking and interfacial friction between the geosynthetic and the aggregate to restrain the development of permanent lateral strains. Considering the relevance of lateral restraint in the quantification of the benefits of geosynthetics embedded within (or adjacent to) unbound aggregate layers, this study focuse

Abstract (sommario):

The inclusion of geosynthetic reinforcement in the piled embankment can help transfer loads to the piles and reduce total and differential settlements. In order to select the appropriate reinforcement material, the reasonable calculation of the deflection and tension is very important. Current design methods usually do not represent the true three-dimensional (3D) nature of the displacements, strains, and stresses of the geosynthetics, and the resulting error may be large and cannot be neglected in some cases. In this study, two- and three-dimensional finite element analyses were conducted to

Abstract (sommario):

A question frequently asked by engineers exposed for the first time to geosynthetics is: “how long do they last”. In this presentation, the author gives an overview of the service life of geosynthetics. Service life is analysed versus the design life and the carbon footprint associated to the construction of a structure. Factors affecting the performance of a geosynthetic used for sealing a canal are presented. A distinction is made between failures occurring because the product did not survive its installation, i.e., survivability-related; failures caused by an inadequate design of the produc

Abstract Concrete columns are commonly used methods to improve the performances of embankments on soft soil strata. To further reduce settlements and stresses on the soft foundation soil, geosynthetic reinforcements are often installed at the base of embankments. Existing design methods for these “geostructures” commonly does not take into consideration both the effect of the embankment construction process and the stiffness of the system components (embankment, soft soil, column and geosynthetics) as design parameters. As a consequence, these approaches do not allow the estimation of the sett

Abstract The application of geosynthetics is state of the art onshore, at the coast and offshore. Geosynthetics complement conventional construction methods, or even replace them and generate advantages for the client, the designer and even more for the environment, e.g. by reducing carbon footprint. Decades of research and experience have resulted in standards and products, which are optimised for long-term performance and reliable application. Geosynthetics, by definition, are products covered by soil and thus protected against impacts or abrasion. As they are often used in contact to water,
