Figure 4.28 The calculated dynamic deformation modulus versus the size <strong>of</strong> loading plate for the<br />
15 cm thick geocell-reinforced RAP base section<br />
The pr<strong>of</strong>iles <strong>of</strong> the HMA surfaces as shown in figure 4.29 were measured from the<br />
reference beam before <strong>and</strong> after the cyclic plate load test. It shows that a depression (equivalent<br />
<strong>to</strong> rutting under traffic) developed under the loading plate <strong>and</strong> some heaving occurred away from<br />
the loading plate after the test.<br />
