3 cards from this section. Quick, good the night before a test.
What is the size of the beam specimen used for flexural strength testing?
Think about the dimensions given in the text.
What testing method is commonly employed to determine flexural strength?
Focus on the method used to apply the load.
What is the modulus of rupture used to measure?
Think about what 'flexural' refers to.
True or False: The third-point loading method applies force at the center of a beam.
Recall where the load is applied.
If you have flexural strength values of three specimens, 3.5 MPa, 3.9 MPa, and 4.2 MPa, how will you determine if the average meets the required 4 MPa?
Use the average calculation.
Discuss the potential consequences of a pavement design that consistently fails flexural strength tests.
Think about the practical impacts of low strength in concrete pavements.
