The stability of geogrid-reinforced soil structure is closely related to the interface characteristics between geogrid and soil. However, creep behavior soil–geogrid still unrevealed. In this study, using a modified stress-controlled pullout device, influence normal pressure, dry density, water content on compacted loess high-density polyethylene (HDPE) investigated. A three-parameter empirical...

Stone columns are a more economical and efficient method to enhance the strength of expansive soils. Using granular blanket over top ordinary stone (OSC) improves drainage distribution applied stress impending from superstructure. The present study studied effect geogrid layers in (GB) OSC numerically using 'PLAXIS 2D'. 'Mohr-Coulomb failure criterion was deliberated for column, blanket, soil, ...

Pullout tests on geogrids have been regarded as the most direct way to investigate geogrid–soil interaction. In pullout geogrids, either static or dynamic load is commonly used for applying vertical loads. order influence of and test results, are carried out analyze mechanical response soils under from large-scale tester. The results show that frequency amplitude significant effects load. inter...

A large number of instability cases and laboratory tests expansive soil slopes show that its shallow layer destruction happens because the insufficient shear strength under usual action low stress repeated dry-wet cycles. We can obtain nonlinear distribution law fitted by generalized power function based on a series considering construct numerical model FISH, to realize dynamic with vertical st...

One of the most effective ways to increase longevity pavement structures is through integration geosynthetic reinforcement. Geosynthetics are synthetic materials such as geotextiles, geogrids, or geocomposites that added interface between subgrade and base layer a structure. To evaluate effect various parameters on structural benefits reinforcement structure low-volume traffic flexible pavement...

This paper presents an experimental study on evaluating the performance of composite geogrid (CGG) reinforced and unreinforced unpaved pavement models using a steel box that has length width height 1.0 m 1.2 respectively. A subgrade CBR 2.5% (unsoaked) was prepared to thickness 500 mm, then granular base compacted top subgrade. Three course thicknesses, namely 200 300 mm 400 were adopted in thi...

Every asphalt pavement rehabilitation, apart from benefits in terms of safety, comfort and speed for users, also has its negative side, i.e., adverse effects on the environment. Some these impacts, such as carbon dioxide equivalent emissions, cannot be limited to immediate environment where works are carried out, but global. In order limit increase average temperature Earth caused by increased ...

The current study examines how an unpaved road behaves when it is installed on top of a soft clay layer that's been strengthened at the subgrade/subbase interface with single geogrid type SS2 used to reinforce laboratory model, and cycling load apply repeated loads model. Subbases without reinforcement over subgrade were built in sizable test box. (1000 mm×1000 mm). results show that using enha...
