3.3. Swell Factor Considerations

Try these first

1. 1.

   What is the swell factor?

   Hint

   Think about how soil density changes when it is excavated.

2. 2.

   What is the default swell factor for dry earth?

   Hint

   Recall the standard value mentioned in the lecture.

3. 3.

   What is the typical swell factor for dry earth?

   • 0.80
   • 1.0
   • 0.60

   Hint

   Think about the properties of dry earth discussed in class.

4. 4.

   When using a push-loaded scraper, the swell factor increases by what percentage?

   • True
   • False

   Hint

   Recall how compaction affects material density.

5. 5.

   If a scraper's empty weight is 43,944 kg and the load weight is estimated at 32,901 kg, what is the gross weight? How does this compare to the maximum rated load?

   Hint

   Sum the two weights and compare with the manufacturer's specified maximum rated load.

6. 6.

   Given a heaped capacity of 23.7 m³ and a swell factor of 0.88, calculate the bank volume for 95% of capacity. How would this affect productivity estimations?
