Geogrids have been extensively used to reinforce bituminous pavements
and have been shown to provide considerable benefits to long-term pave
ment performance. The paper describes the development and testing of a
composite combining a stiff polypropylene geogrid with a geotextile,
thus producing a material with the handling and installation benefits
of a geotextile combined with the performance benefits of a stiff geog
rid. A case study detailing the use of the composite reinforcement is
also presented. Copyright (C) 1996 Elsevier Science Ltd.
