*The simple shear test at constant height and the frequency sweep at constant height are conducted on the
same two specimens at both temperatures.
Notes:
Te_r(PD)is the calculated effective temperature for permanent deformation.
T_(FC) is the calculated effective temperature for fatigue cracking. See chapter 4 of the
SUPERPAVE® Mix Design Manual for New Construction and Overlays.

4.3.2 Assemble the test assembly. As required, bond the platens to the test specimen;
where required, surround the specimen with a membrane; and affix the linear variable
differential transducers (LVDTs) to the specimen in the configuration required by the specific
test.
4.3,3 Load the completed test assembly into the shear test device.

4.3.4 Conduct the test per SHRP M-003 and the manufacturer's instructions for the
test device.
