The author describes a new concept developed in the past 12 months at Strathclyde University. The method uses cut up pieces of Netlon type 7 polypropylene mesh which interlock with the adjacent soil particles to form an aggregation. These aggregations are locked together by the surrounding mesh elements to form a coherent matrix with improved stress resistant properties and increased ductility. The mixing of the snippets - in some cases ribbons - of the mesh does not affect the permeability of the soil. Tests have shown that a soil with as little as 0.5% by volume of the snippets of mesh has an increased load bearing capacity of from 2% CBR value to 20%. Patent applications for the concept have been filed in a number of countries, says Netlon, which gave financial support to Strathclyde to help with the research. (TRRL)
