Dynamic Cone Penetrometer Criteria for Evaluation of Subgrade and Aggregate Base Courses
This report summarizes the findings of one-year research study sponsored by the North Carolina Department of Transportation on the use of the Dynamic Cone Penetrometer (DCP) to develop a pavement distress evaluation model. Work included laboratory and field testing programs as well as modeling effort. In this report, a method was proposed by which the DCP PR data were utilized to evaluate pavement distress state. Such evaluation is needed on regular basis in order to categorize the implementation of rehabilitation measures. The principle idea was to use the DCP data to discem the integrity of the subase and ABC layers. Accordingly, if the structural integrity of sub grade and ABC layers is found to be adequate, maintenance measures can include simply resurfacing or treating the surface layer. However, in situations where the structural integrity of the ABC, the subgrade, or both, is found inadequate, extensive stabilization and soil improvement measures maybe needed and resurfacing alone will not be sufficient. The laboratory work on the subgrade materials was performed on three residual soil types taken from test sites in Davidson County, North Carolina.
