Identifying the key parameters that influence geogrid reinforcement of railway ballast
S F Brown,J. Kwan,Nick Thom +2 more
TL;DR: In this article, a series of experiments are described involving the full-scale simulation of geogrid reinforcement for railway ballast, which allowed the key parameters influencing the reduction in vertical settlement (permanent deformation) under repeated loading to be studied.
Journal ArticleDOI
Behavior of geogrid-reinforced ballast under various levels of fouling
TL;DR: In this article, a study of how the interface between ballast and geogrid copes with fouling by coal fines was presented, and the results indicated that geogriders increased the shear strength and apparent angle of shearing resistance, while only slightly reducing the vertical displacement of the composite geogrig-ballast system.

Stress-Strain Degradation Response of Railway Ballast Stabilized with Geosynthetics
TL;DR: In this article, the results of cyclic drained tests and numerical studies carried out on a segment of model railway track supported on geosynthetically reinforced railroad ballast bed were evaluated using a large-scale prismoidal triaxial chamber.
Journal ArticleDOI
Laboratory performance of unpaved roads reinforced with woven coir geotextiles
TL;DR: In this article, the effect of coir geotextiles on the performance of reinforced and unreinforced laboratory pavement sections was investigated using two base course thicknesses and two types of woven coir geo-textex.
Journal ArticleDOI
The lateral displacement response of geogrid-reinforced ballast under cyclic loading
TL;DR: In this article, a large-scale process simulation test (PST) apparatus that can capture the lateral strain variation upon loading is described, and the lateral deformation profiles along the ballast depth have been measured and the geogrid influence zone (GIZ), defined as the distance to which the effect of geogrids in arresting the lateral displacement of ballast exists, has been determined.

Associated and non-associated visco-plasticity and plasticity in soil mechanics
TL;DR: The visco-plastic model is established as a realistic general description of soil behaviour as well as a computationally convenient fiction for solving any properly formulated plasticity problem as discussed by the authors.

Bearing Capacity Tests on Reinforced Earth Slabs
Jean Binquet,Kenneth L. Lee +1 more
TL;DR: In this paper, a 3-in. (75mm) wide strip footing on sand reinforced with strips of aluminum foil was used to test the bearing capacity of three foundation conditions: (1) uniform density sand to large depth; (2) sand overlying an extensive soft layer; and (3) sand overlaying a potential cavern or localized weak pocket.

Large model spread footing load tests on geosynthetic reinforced soil foundations
Michael T. Adams,James G. Collin +1 more
TL;DR: In this article, the potential benefits of geosynthetic reinforced soil foundations are investigated using large-scale model footing load tests, and the results indicate that the use of girders may increase the ultimate bearing capacity of shallow spread footings by a factor of 2.5.
