A CASE HISTORY - STABILIZATION FABRIC PROVIDES SUPPORT FOR A MAJOR ROADWAY WIDENING. REINFORCED SOIL AND GEOTEXTILES, PROCEEDINGS OF THE GEOTEXTILES CONFERENCE HELD AT THE INDIAN INSTITUTE OF TECHNOLOGY, BOMBAY, INDIA, DECEMBER 8-9, 1988

A roadway stabilization woven geotextile, Mirafi 600X, was selected and installed during widening of a section of Drane Field Road in Lakeland, Florida, USA. Available subsoil information established the presence of compressible clays (AASHTO Classification-A6) within the critical zone below the subgrade elevation and presence of shallow groundwater table. An active force main existing within 30 cms of the subgrade elevation created complicated boundary conditions. The alternate of installation of the geotextile fabric in lieu of excavation/replacement of clays (in conjunction with the installation of the underdrains) was selected. The fabric was installed at the interface of the subgrade and the limerock base course. Its primary functions were to provide separation, containment and tensile reinforcement. Continuous monitoring of the fabric installation and laydown operation provided the initial support and helped improve subsoil/subgrade/pavement supporting capability of the soil-geotextile system. Roadway widening has been completed and it is currently carrying the traffic volume and loads. For covering abstract of the conference, see IRRD 836241. (Author/TRRL)
