The Dynamic Cone Penetrometer (DCP) was first introduced to Mn/DOT at the Minnesota Road Research Project (Mn/ROAD). Since 1993 the DCP has been used by Mn/DOT as an acceptance tool for the compaction of pavement edge drain trenches. In 1999, the Penetration Index Method for compaction acceptance of base aggregate Classes 5, 6, and 7 was adapted by Mn/DOT, which requires the use of the DCP as the testing device.
The Mn/DOT specifications are found in Modified Penetration Index Method
