Geotechnical engineering problems involved in the design and construction of approach embankments of bridges and grade separators are summarized. An overview of geosynthetics and their applications in bridge approaches is given. Geosynthetic solutions for embankments on poor ground viz. basal reinforcement, prefabricated vertical drains and load transfer platforms are described. Applications of geosynthetics in slope face reinforcement, slope erosion control and reinforced soil walls and slopes are presented. The evaluation of long-term design strength and durability of geosynthetic reinforcement for permanent
structures is discussed.
