Course Learning Objectives:
The Objectives of the course are to impart to the student

• An overview of the evolution of new construction materials in geotechnical engineering and to initiate geosynthetic materials.
• Understanding the properties and the testing methods of different types of materials of gosynthetics.
• The knowhow of manufacturing methods, uses and applications of geotextiles, geogrids, geomembranes and geocomposites.
• The concepts of designing geosynthetics for the functions of separation, reinforcement, stabilization, filtration, drainage and moisture barriers.
• Designing criteria of reinforced earth retaining walls, gabions, pond liners, covers for reservoirs, canal liners, landfill liners, caps and closures, dams and embankments.
• Additional advantages of geocomposites, geowebs and geocells, and moisture barriers and natural geotextiles etc. for applications to meet various functions.

Course Outcomes
At the successful completion of this course the student will be able to

• Realize the need and demand for the use of geosynthetic materials in the field of geotechnical construction works.
• Conduct required laboratory and field tests to obtain the properties of different materials of geosynthetics.
• Distinguish and describe various manufacturing methods of geotextiles, geogrids, geomembranes and geocomposites.
• Understand concepts and could design the geosynthtics for the functions of separation, reinforcement, stabilization, filtration, drainage and moisture barriers.
• Design reinforced earth retaining walls, gabions, pond liners, covers for reservoirs, canal liners, landfill liners, caps and closures.
