Abstract
  • This work describes a novel method of soil stabilisation at meso-scale which involves mixing into the soil molecularly oriented mesh elements in the form of squares, rectangles or ribbons. Laboratory compaction, CBR, permeability, triaxial, repeated loading, long term loading (creep) and model footing tests are detailed in which 50 mm square, or 50 x 100 mm rectangular mesh elements are mixed with various soils in order to identify the important properties of the mesh and the effect of the mesh element content on the behaviour of the stabilised soils. The results indicate that the basic operating mechanism is that each mesh interlocks with the adjacent soil particles to form an aggregation and these aggregations are locked together by the surrounding mesh elements to form a coherent matrix with improved stress resistant properties, increased ductility and unaffected permeability. These benefits are obtained even when the mesh element content is small.
