3.6.7 Dynamic Cone Penetration Test<br />
Figure 3.14 Vane shear test apparatus<br />
Dynamic Cone Penetration (DCP) tests (ASTM D6951-03) were carried out at four<br />
different locations approximately 24 hours after the placement <strong>of</strong> the RAP base course. The<br />
objective <strong>of</strong> this test was <strong>to</strong> determine the CBR pr<strong>of</strong>ile <strong>of</strong> subgrade <strong>and</strong> base course in each test<br />
section. The following relationship established by Webster et al. (1992, 1994) was used <strong>to</strong><br />
estimate the CBR value.<br />
