1.2.2. Dead load (water) is added to give a weight of 100 to 400 kN.

Try these first

1. 1.

   What is the primary function of pneumatic tyred rollers?

   Hint

   Think about what rollers do in construction.

2. 2.

   What weight range do pneumatic tyred rollers typically achieve with added dead load?

   Hint

   Consider the weight specified for adjustment.

3. 3.

   What is the weight range achieved by pneumatic tyred rollers when water is added as dead load?

   • 50 to 150 kN
   • 100 to 400 kN
   • 200 to 250 kN

   Hint

   Refer back to the specified weight range.

4. 4.

   True or False: Pneumatic tyred rollers are suitable for very soft clay.

   • True
   • False

   Hint

   Consider the soil limitations mentioned.

5. 5.

   Design a compaction strategy for a construction site with varying soil types. How would you incorporate the use of pneumatic tyred rollers effectively?

   Hint

   Consider adapting techniques based on soil characteristics.

6. 6.

   Evaluate the potential impact of varying soil conditions on the compaction effectiveness of pneumatic tyred rollers.

   Hint

   Think of how different soil types react to pressure.
