Railway track is one of the most demanding environments for geosynthetic materials. The repeated dynamic loading from passing trains — thousands of load cycles per day on busy lines — combined with the need…
Permafrost — ground that remains at or below 0°C for two or more consecutive years — underlies approximately 25% of the Earth’s land surface, covering vast areas of Siberia, Canada, Alaska, Scandinavia, the Tibetan…
grid embedded in nonwoven filter layers One-step easy installation Optimal interaction with the sub-grade High modulus, low strain (Enkagrid TRC) Geogrid and nonwoven geotextile together Functions: Stabilization+ Filtration+ Separation
Uniaxial geogrids were applied in this railroad project between Aliaga-Izmir cities. Geogrids were installed as several layers and the specially chosen soil between the layers was compacted. Like the roads in railroad backfills uniaxial…
Wickdrains — Methods of installation Water Jetting Ramming Pushing, modern preferred method Pushing + vibration Pushing + water jetting
Water in road construction weakens the substructure and can have disastrous effects on the structure as a whole. Dynamic loads from road traffic generate a pumping effect, drawing water from the subsoil up into…
Enkamat and wiremesh hold soil particals, stones and seeds. The Enkamat functions as a griplayer for hydroseeding. First Enkamat is installed on the slope and then on it wiremesh. As the green of the…
On weak soils, for road construction contractors generally need a thick layer of base course. Using geogrids as reinforcing layers can help to reduce the required thickness of the unbound base course stabilizing structures…
Kocaeli free zone project has a harbour inside the project. There is a heavy traffic of trucks. To prevent or reduce partial settlements on the roads due to the heavy truck traffic special geogrid…
Civil Engineers, planners and contractors aim for direct economic highways, airports and other traffic routes using natural resources as efficiently as possible in their construction: this often means having to build on poor soils…
