THE USE OF GEOSYNTHETICS IN THE A5 FAZELEY BYPASS

This article shows how the use of geosynthetics has solved several problems with the A5 Fazeley Bypass, a major trunk road scheme in Staffordshire, England. The project includes the provision of 8.1km of dual 7.3m wide carriageway and 2.0km of 7.3m wide single carriageway side roads, with associated structures and grade-separated interchanges. Early in the scheme's design stage, it became apparent that geogrids could be useful, mainly in basal reinforcement of embankments and stability of side slopes. As the scheme's design progressed further, opportunities arose to use other geosynthetic products in several application areas, including: (1) the contractor's temporary works design; (2) subgrade reinforcement; (3) erosion control and protection; and (4) drainage mitigation measures. The article discusses individually each of these applications, its problems, and its solutions. This complex scheme showed the many simple and innovative ways in which modern geosynthetic products can help design engineers. Their benefits in reducing costs are especially important for both specifiers and end users.
