This report describes test procedures used to measure the minimum soil strength necessary for a vehicle to consistently complete one pass successfully one-pass Vehicle Cone Index , VCI1. The VCI1 is a vehicle performance metric used to quantify mobility on soft soils. The report scope covers the specific procedures that should be used for evaluations in support of ground vehicle acquisition. The procedures define site selection criteria, test lane layout, soil data collection procedures, and analysis methodology to determine the VCI1. Rationale behind the test procedures and detailed descriptions of the principal soil strength measurement techniques are provided in supporting appendices.
