ends. Specimens were instrumented with three linear variable displacement
transformers (LVDTs), each spanning 100 mm, for measurement of axial (vertical)
deformations; the LVDTs were mounted to the periphery of the specimen 120° apart. It
should be noted that lateral strains were not monitored.
The complex modulus test results are shown in Tables 2.3.3 to 2.3.6. Each table
presents the dynamic moduli values and the corresponding phase angles. It was found,
separately for each mix, that the initial differences in voids did not affect the test results
in a statistically significant manner. Therefore, each value in these tables constitutes the
average result of four separate tests.
