CONCEPT OF REMOTELY DELIVERED TRAFFICABILITY PROBE

A concept of remotely delivered trafficability probe is presented. The trafficability probe provides soil information from which a soil rating cone index (RCI)--the final measure of soil trafficability--can be calculated. A soil sample of the critical trafficability layer is remotely obtained during probe penetration and a remolded cone index (CI) of the sample is measured. An in situ CI of the critical soil layer is also measured. A remolding index (RI) can then be calculated from a ratio of the CI values. The RCI is obtained from the product of the RI and the measured in situ CI. Comparison of this RCI with the vehicle cone index (VCI) assigned to given vehicles determines the trafficability of the vehicle(s) in the vicinity of the soil probe.
