A new in-soil tensile test apparatus was developed to simulate the stress condition of geosynthetics in a real working state. An with or without friction conducted, along in-air tests eight types geosynthetics, evaluate properties, including load and secant stiffness under different confining stresses using various methods. Under confinement, properties increased growing which were greater than...

Geosynthetics have proven to provide sustainable solutions for geotechnical and geoenvironmental problems when used with natural materials. Therefore, the expected benefits environment geosynthetics are associated unconventional or alternative construction materials will be even greater. This paper addresses use of wasted in different applications. The potential uses such as tires, demolition w...

John S. McCartney received BSCE and MSCE degrees from the University of Colorado Boulder and a PhD degree in civil engineering from the University of Texas at Austin. Dr. McCartney’s research interests include unsaturated soil mechanics, geosynthetics, and thermally active geotechnical systems. He has received several research awards, including the NSF Faculty Early Development (CAREER) Award i...

Characterization of a geosynthetic is necessary for its effective use in various field application of reinforced soil structure. In this paper, a new type of geosynthetic has been evaluated for its interaction properties for different backfill soils using direct shear device. The test results are compared based on the type of soils, inclusions, and interface mechanical properties. Three backfil...

Over the last fifteen years increased research interest has been observed on the dynamic response and stability issues of landfills. Nevertheless, there are still important aspects that have not been yet fully resolved. Geosynthetic liners, constructed to isolate waste material from the environment, are undoubtedly one of the most important issues related to seismic design of landfills, since a...

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, s...
