4.7.4. Geosynthetics

Try these first

1. 1.

   What are geosynthetics?

   Hint

   Think about the materials' role in engineering.

2. 2.

   Name two types of geosynthetics.

   Hint

   These are common examples you might have heard of.

3. 3.

   What is the primary role of geosynthetics?

   • Improve drainage
   • Reinforce soil
   • Reduce costs

   Hint

   Consider how they interact with the soil.

4. 4.

   True or False: Geotextiles are used to separate soil layers.

   • True
   • False

   Hint

   Think about the term 'separation'.

5. 5.

   Design a flexible pavement using geosynthetics in a high-traffic area. What considerations will you have for material selection and application?

   Hint

   Think about traffic loads and how they affect the underlying layers.

6. 6.

   Evaluate the effectiveness of geosynthetics in a past pavement project. What metrics would you use to assess performance?

   Hint

   Consider both financial and physical aspects.
