Protocol P46
Test Method for Resilient Modulusof Unbound Granular Base/Subbase Materials and Subgrade Soils (UG07, SS07)


Perform the calculations to obtain resilient modulus values using the tabular arrangement shown on Worksheet T46. The resilient modulus value is computed for each of the last 5 cycles of each load sequence. These values are subsequently averaged on the data sheet.
