Chapter 3 Material Properties <strong>and</strong> Experimental Setup<br />
This chapter presents the characteristics <strong>of</strong> the materials as well as the experimental set-<br />
up <strong>of</strong> the large-scale cyclic plate load tests conducted in this study. The cyclic plate load tests<br />
were conducted in a large geotechnical test box equipped with a servo hydraulic MTS loading<br />
system available at the University <strong>of</strong> Kansas.<br />
3.1 Base Course<br />
The base course material used in this study was RAP, which was provided by R.D.<br />
Johnson Excavating, Co. in Lawrence, Kansas. The RAP was milled <strong>of</strong>f from a city street in<br />
Lawrence. The binder content <strong>of</strong> the RAP was determined by the ignition method (ASTM<br />
D6307) <strong>and</strong> the centrifuge method (ASTM D2172). The gradation <strong>of</strong> the RAP aggregate was<br />
determined for the sample extracted by the ignition method before <strong>and</strong> after compaction tests.<br />
The gradation curves (fig. 3.1) <strong>of</strong> the RAP aggregates before <strong>and</strong> after compaction show that<br />
compaction did not affect the gradation <strong>of</strong> the RAP aggregate.<br />

after compaction (Thakur 2011)<br />
