Widespread
implementation of the DCP-DN design method for low volume roads has been
promoted internationally over the past decade or so. The method has progressed
from a simple determination of the in
situ CBR investigation based on DCP-CBR correlations with respective cover
requirements to a more sophisticated method using the DCP penetration data
directly and omitting any need to use correlations with the CBR. This paper
summarises the development of the method, and some of its advantages and compares the design structures with other
recognised and widely implemented designs.
