JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD

Course Objectives:

• 1. To determine properties of rock samples
• 2. To determine strength and Module of rock sample for the design purpose
• 3. To determine the strength and other properties required for geotextile.

Course Outcomes

At the end of the course, student will be able to understand the behavior of rocks

and Geosynthetics for various loads, in order to use these properties in the design of geotechnical structures.
