THE FILTRATION BEHAVIOUR OF CONSTRUCTION FABRICS UNDER CONDITIONS OF DYNAMIC LOADING

The use of a construction fabric at the subgrade/sub-base interface in road construction, for the prevention of upwards migration of clay particles into the sub-base is considered. This article describes tests using a cohesive subgrade soil, a number of fabric types, and a single sized 20 mm aggregate as sub-base material. The soil was compacted in a steel box, covered with the fabric to contain the aggregate which was subsequently saturated. The stress normal to the place of the fabric was varied sinusoidally for 24 hours. The aggregate contamination due to upward movement of the clay particles was estimated. Test results for various fabrics, and a no-fabric control test are tabulated and discussed. (TRRL)
