...F. Song; W. Chen; Y. Nie; L. Ma Cellular geosynthetics have been widely used in engineering practices for their enhanced confining effects. However, limited research has been reported on methods of evaluating the required stiffness and strength of cellular geosynthetics based on the strength...

... study proposes a single power function that quantifies the effects of the amount of cement and porosity on the unconfined compressive (q_u) and split tensile (q_t) strength of fibre-reinforced fine-grained soil-cement mixtures. The practical value of the equation...

... small beads of expanded polystyrene (EPS) have become widely used, mixed with sandy soils and stabilised with cement. The reduction of weight due to the inclusion of such EPS beads is therefore beneficial. Nonetheless, such inclusion can degrade the fundamental strength and deformation properties...

..., such as a steeper slope and different geosynthetics; (ii) published values of interface strength/friction angle should not be used for final design, instead site-specific interface testing should be used; (iii) final cover slope angle should not exceed the lowest geosynthetic interface strength in the cover system...

...A. Sawicki; K. Kazimierowicz-Frankowska Experimental results dealing with the influence of strain rate on the load-strain characteristics of five different geosynthetics are presented and discussed, including the load-strain curves and the strength of these materials. Theoretical and empirical...

... interface relationship between shear stress and shear displacement interaction. Such a description of interface strength and stiffness characteristics is needed in analytical models used to predict a displacement response of geosynthetic-reinforced soil structures. Due to the extensibility of geosynthetics...

Raymond LABORATORY SURVIVABILITY OF NONWOVEN GEOTEXTILES ON OPEN-GRADED CRUSHED AGGREGATE ABSTRACT: A laboratory method of assessing survivability of a nonwoven geotextile laid on open-graded crushed aggregate was developed. Preliminary...

...H.T. Eid; C.K. Doerfler Torsional ring shear tests were performed to evaluate the effect of shear displacement rate on the internal shear strength of a needle-punched geosynthetic clay liner (GCL) under different normal stresses. The test results suggest that the internal shear strength...

..., slope height, physical characteristics, e.g. high unit weight, of the waste, and possibly the overlying smooth geomembrane/geonet interface played a significant role in the movement. Design recommendations for interface strengths and stability analyses are also presented. geosynthetics Geosynthetic...

... material. Conversely, shearing of the hydrated GCL against a textured geomembrane resulted in failure occurring at the GCL bentonite/textured geomembrane interface. The order of hydration and normal stress application was found to significantly affect the GCL/textured geomembrane interface shear strength...

...T.D. Stark; H.T. Eid Ring shear tests were performed to evaluate the effect of bentonite on the interface shear strength between a geomembrane and a reinforced geosynthetic clay liner (GCL), and the internal shear behavior of reinforced GCLs. The tests yielded an interface shear strength...
