2 cards from this section. Quick, good the night before a test.
What is the dynamic complex modulus?
Think about what kind of materials this modulus describes.
Why is selecting the correct frequency important in dynamic modulus testing?
Consider how traffic loads affect pavement.
What does the dynamic complex modulus characterize?
Think about what types of materials this applies to.
True or False: The dynamic modulus remains constant regardless of loading frequency.
Consider how traffic patterns affect performance.
A road uses a visco-elastic material that exhibits a dynamic modulus of 500 MPa at a frequency of 10 Hz. How would this modulus change if the frequency increases to 20 Hz?
Consider the relationship between frequency and material response.
Propose a set of conditions that should be maintained during a dynamic modulus test to ensure accurate representation of traffic stress on pavement.
Think about what real traffic conditions involve.
