Considerations Regarding Vehicle Cone Index for Fine-Grained Soil

Digital Object Identifier 10.32754/JMT.2018.2.07 39 Abstract—Vehicle Cone Index (VCI) is the most representative parameter to establish the vehicle capability to overpass the tough conditions caused by the soft soil. Its importance is emphasized by the fact that it has been recently included in TOP 02-2-619A. According to this test operations procedure, VCI can be both estimated and measured. Original methods – prediction with TruckSim software, as measurements in a natural fine grained soil for a 4×4 military vehicle, are presented in the study. The difficulties encountered with site selection, equipment used and test lane procedure represent truly learned lessons for all those concerned with offroad mobility. Moreover, the test results and the analysis done in this paper could be a reference for future vehicle pass simulations.
