MINDING THE QUALITY AS THE WIDTH SPREADS

The use of artificial fibre fabrics in civil engineering was discussed at a recent UMIST conference. The most common fibres used are mixtures of propylene and nylon or polyethylene. The Forestry Commission claimed that savings could be made by its use in embankments and drains. Fabric also allowed construction depths to be reduced in conventional road embankments, particularly where the ground is poor. The material has also been successfully used in site access roads. Difficulties have been encountered in the formulation of tests to evaluate the performance of fabrics and with edge failures of fabrics used in roads. Fabrics have been used to separate layers of fill in drainage works reducing the clogging of drains. Surface and sub-surface fabric-wrapped French drains have been used on the A9 road in Scotland. Artificial fabrics are also being used to strengthen roofing felts, the stronger polyester fibre allowing a two-layer construction instead of three. /TRRL/
