One of the efficient techniques to improve the behavior of the paved road under traffic loads is implementing the geosynthetic material in the sub-base or the soil under the road. In the past years, many researches have been done about this topic, but the study on the effect of soil/load conditions on the performance of the rehabilitated paved road by geogrid in order to investigate the effecti...

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...

This paper presents the effect of geogrid tensile strength by calculating pullout resistance and geogrid-soil interaction mechanism. In order to investigate this interface, a series of pullout tests have been conducted by large scale reformed direct shear test apparatus in both cohesive and granular soils. In numerical, finite difference software FLAC3D has been carried out on experimental test...

large size direct shear tests (i.e.300 x 300mm) were conducted to investigate the interaction between clay reinforced with geogrids embedded in thin layers of sand. test results for the clay, sand, clay-sand, clay-geogrid, sandgeogrid and clay-sand-geogrid are discussed. thin layers of sand including 4, 6, 8, 10, 12 and 14mm were used to increase the interaction between the clay and the geogrid...

This paper reports the results of model loading tests performed on an eccentrically loaded strip foundation supported by multi-layered geogrid-reinforced sand. Only one type of geogrid and sand at one relative density of compaction were considered. Based on the present laboratory test results, an empirical relationship for the reduction factor has been developed. This relationship can be used t...

the pull- out strength of the reinforcement has a significant role on the function of the most reinforced soil structures. since the coarse grain soils have a better interaction with the reinforcement, they are mostly used in these structures. in most situations, we have to transfer these granular soils from the borrow area, usually far from the site of the project. this will impose a considera...

Abstract This paper presents the summary of experimental program to evaluate potential KOBM (Klockner Oxygen Blown Maxhutte) slag stabilize geogrid-reinforced subgrade soil in Suva, Fiji. is a by-product steel manufacturing process New Zealand. The standard California bearing ratio (CBR) laboratory tests were performed on samples with various combinations geogrid and slag, along other geotechni...

Geogrids are commonly used in transportation applications for stabilization and reinforcement due to their higher tensile strengths compared to geotextiles as well as the stiffness improvement they provide through arresting and interlocking granular particles in the geogrid apertures. Influenced by many factors, such as the aperture shape and size of geogrid, the degree of interlocking contribu...

Geogrids provide reinforcement for aggregate materials through interlocking between granular particles and geogrid apertures. The reinforcement or stabilization effect of a geogrid can be quite different when used with similar aggregate types but having different particle size distributions. This paper describes recent research efforts at the University of Illinois focused on triaxial compressi...
