Full-Scale Field Study Of A Geogrid-Reinforced Unpaved Road System, Abdalla El Tawati
Full-Scale Field Study Of A Geogrid-Reinforced Unpaved Road System, Abdalla El Tawati
Electronic Thesis and Dissertation Repository
Geogrids are widely used to improve the performance of unpaved roads constructed over weak subgrade. However, the behavior of geogrids under traffic loads and their reinforcing mechanisms, as well as the resulting benefits to the roadway performance are not well understood. A full-scale field study was conducted to quantify the effectiveness of geogrids in unpaved roads, evaluate their reinforcing mechanism, and identify which geogrid properties are most directly related to performance improvement. Ten full-scale unpaved road test sections were constructed with varying relevant parameters including geogrid aperture shape, geogrid tensile modulus, and thickness of the base course layer. Five of …
Static And Seismic Performance Of Geosynthetics-Strengthened Pile Foundations, Ahmed M. Taha
Static And Seismic Performance Of Geosynthetics-Strengthened Pile Foundations, Ahmed M. Taha
Electronic Thesis and Dissertation Repository
Geosynthetic reinforcement in earth structures has been used extensively over the last two decades. Extensive research has been carried out to investigate solutions to enhance the lateral stability of pile foundations. This research is motivated by the need to install piles in sites characterized by soft subsurface soil conditions, and often times, in seismic active areas. This research work explores an innovative use of geosynthetics to enhance the lateral performance of pile foundations. The static and seismic soil-structure-interaction behaviors of geosynthetics-reinforced pile foundation systems were evaluated using a series of reduced scale physical model tests performed on a shaking table …
