  • 80-85%

💡 Hint: Think about load-bearing requirements.

Question 2

True or False: The acceptance criteria for subgrade is lower than that of the base layers.

Challenge Problems

Push your limits with challenges.

Question 1

You are tasked with designing a highway pavement. Your laboratory tests indicate the Modified Proctor MDD is 140 lbs/ft³. What are the compaction requirements for each layer? Discuss the impact of not meeting these requirements.

💡 Hint: Remember the percentage ranges for each layer.

Question 2

Given the soil compaction percentage data from a recent construction site, analyze the potential risks to pavement longevity if the subbase was only compacted to 92% of MDD, whereas it should have been 95-100%.

💡 Hint: What are the consequences of inadequate support for additional layers?
