Geosynthetic Reinforcement For Unpaved Roads – Recent Experience, Ciaran Reilly, Keith Nell
Conference papers
Modern geosynthetic materials, including geotextiles and geogrids, are often used to generate savings in materials and time on construction projects. Geosynthetics are used as reinforcement and separation membranes for unpaved roads that are supported by low strength or unsuitable subgrades. When geosynthetics are used, unsuitable subgrades can be left in place and reduced thicknesses of road base are required. This paper reviews the design methods currently used to build geosynthetic reinforced unpaved roads and documents the validation of these design approaches. A number of recent case histories of projects in the UK and Ireland are outlined, showing the use of …
