4 cards from this section. Quick, good the night before a test.
What does the k-value represent in pavement design?
Think about how well it supports loads.
Which test is used to determine the k-value?
Consider the name that involves loading a plate.
What is the k-value used to measure in pavement structures?
Consider what stiffness relates to in materials.
The Plate Load Test is essential for determining which of the following?
Think about the importance of testing for design purposes.
A circular plate of diameter 30 inches is loaded with 4000 lbs. If the settlement measured is 0.4 inches, calculate the k-value and discuss what this indicates about the subgrade.
Remember to calculate the area of the plate first.
Discuss the impacts of frost and moisture variations on the k-value over time. What engineering practices could mitigate potential decreases in k-value?
Think about how environmental factors affect soil behavior.
