GEOTEXTILE-GRAVEL SYSTEM FOR DEEP FOUNDATION IMPROVEMENT, ALLHAU BYPASS EMBANKMENT, AUSTRIA
This short article describes the use of geotextiles to improve the foundation of the Allhau Bypass embankment in Austria. The 18m embankment crosses a 300m wide swamp. The subsoil mainly consists of very soft sandy silts and loose sands, and the water table is very close to the ground surface. A layer of polypropylene needlepunched nonwoven Polyfelt TS700 geotextile was laid out perpendicular to the road axis. A layer of 800mm gravel was placed on this to provide a working surface to install the prefabricated vertical drains (Mebra drains) and the gravel piles. After these had been installed, and 2 culverts erected, the gravel layer was completed to 1m thickness and another layer of geotextile laid over it. Brief details of the monitoring and performance of the embankment are provided. For the covering abstract see IRRD 865821.
