Geosynthetics Testing Laboratory

NPTEL is offering online course for undergraduate/ postgraduate students in Geosynthetics Testing Laboratory.

About the course:

• This course will show how to conduct the various types of tests used for geosynthetic testing.
• Each experiment of geosynthetic testing is presented with brief introduction covering the important details of the experiment, the theory and the purpose for which it is to be performed, followed by the detailed explanation of apparatus required, procedure and specimen calculations.
• These should enable students to compute the results of experiments very easily.

Course Layout:

• Week 1: Module 1: Physical Properties: Introduction; Types of Geosynthetics; Functions; Mass per unit area, thickness, specific gravity…, Module 2: Mechanical Properties: …Tensile strength and trapezoidal tear strength; Tensile Modulus;
