Use of Geotextiles to Extend Aggregate Resources

Source

The use of an interlayer of geotextiles or fabrics was found to allow a substantial reduction in the aggregate layer thickness required to provide a given level of performance formance for aggregate-surfaced roads over soft soil deposits. Experimental results were used to derive equations that relate key performance parameters for aggregate-soil systems containing Typar 3401 fabric. Numerous laboratory and field studies concerning the use of fabric to reinforce aggregate layers were cited. Various design methods for specific commercial product lines and two general design methods were used to illustrate typical ranges in aggregate savings that may be effected by use of fabric.
