<p><p><strong>Reference(s):</strong></p><p><em>Christopher et al. (2010)</em></p><p><strong>Method Summary</strong></p><p>The DCP device consists of a steel shaft with a conical tip which is driven into the soil with either a 10 or 18 pound hammer. DCP testing typically allows the tip to be driven to a depth of 3 feet. The principle behind the DCP is that a direct correlation exists between the strength of a soil and its resistance to penetration by solid objects.

Project Summary/Scope: 

<p><p>Cost documents are not developed for this technology due to the localized nature of excavation and replacement. Users are encouraged to submit relevant cost information for routine excavation of soils and their replacement through traditional compaction in their localities.</p></p>
