Fabrics have found many applications in civil engineering, notably in geotechnics, and new uses are constantly being developed. Temporary construction roads have been formed by placing permeable fabric membranes on cohesive subgrades which are then covered by layers of roadstone. Geotextiles (fabrics used in geotechnical engineering) have also been used in subsurface drains, in the exposed faces of earth embankments and groynes used for coastal protection and river training schemes, and on the subgrade beneath road or railway embankments to prevent upward migration of fines from cohesive subgrades into the crushed stone base materials. There is now growing interest in using fabrics as reinforcement, particularly in road construction and earthworks. It has been suggested that the inclusion of a geotextile between subgrade and the sub-base or within the sub-base will strengthen the total depth of construction and so reduce the overall cost. The possibility of using fabric reinforcements in reinforced earth structures has been actively considered and tested. A 2-year study (at Queens University Belfast, Ireland) of the stabilization of highway embankments with polypropylene textiles is discussed. The selection of a suitable fabric for a particular purpose is influenced by three factors: the specific civil engineering job, the fabric type, and the soil or rock type in which the fabric is to be placed. There is a need for information obtained from field and laboratory sources which could then be correlated and used in the establishment of practical lab tests which will form the basis for the selection and specification of geotextiles.
