4.8. Quality Control and Assurance

Try these first

1. 1.

   What is the purpose of field density testing?

   Hint

   Think about measuring weight in a specific volume.

2. 2.

   Why is moisture control important in pavement construction?

   Hint

   Recall the relationship between water and soil's strength.

3. 3.

   What is the main goal of quality control in pavement construction?

   • To improve aesthetics
   • To ensure structural integrity
   • To reduce costs

   Hint

   Think about what quality control aims to protect.

4. 4.

   True or False: Moisture control is unnecessary during soil compaction.

   • True
   • False

   Hint

   Recall how moisture affects soil strength.

5. 5.

   If the field density test reveals a density lower than specified, what remediation steps might be necessary, and how could this affect the overall pavement design?

   Hint

   Think about what options you have when facing weak soil.

6. 6.

   Discuss how seasonal weather changes might impact moisture control and what adjustments should be made in testing frequency during rainy seasons.

   Hint

   Consider how rain affects soil compared to dry conditions.
