Laboratory R-Value vs. In-Situ NDT Methods - NM04MSC-02 View Report

The research reported herein evaluates the possibility of replacement of the current method of R-Value estimation used in the preparation of subgrade and base course materials. This research was conducted by measuring stiffness values of said subgrade or base course using three candidate devices: the Clegg Impact Hammer, the GeoGauge, and a Dynamic Cone Penetrometer. The stiffness values were then correlated with laboratory determined R-Values of the same material to find a mathematical relationship with the candidate devices.
