Soil Cone Index impact on aircraft ground performance

2020 IEEE 7th International Workshop on Metrology for AeroSpace (MetroAeroSpace), 2020
The paper presents research conducted in order to assess the impact of soil parameters on an aircraft ground performance. It describes the Cone Index parameter widely used to characterize specific soils as well as a method of measurement using the soil ...

SIMULTANEOUS SOIL MOISTURE AND CONE INDEX MEASUREMENT

Transactions of the ASAE, 2004
Soil compaction can restrict root growth and water infiltration, resulting in yield reduction. Maps of yield monitor data aid in visualization of variations in yield, without identifying underlying factors for these variations. Soil penetration resistance can help identify areas where soil physical characteristics are negatively impacting yield ...

A New Periapical Index Based on Cone Beam Computed Tomography

Journal of Endodontics, 2008
The purpose of this study was to evaluate a new periapical index based on cone beam computed tomography (CBCT) for identification of apical periodontitis (AP). The periapical index proposed in this study (CBCTPAI) was developed on the basis of criteria established from measurements corresponding to periapical radiolucency interpreted on CBCT scans ...

Development of Technique for Vehicle Specific Off-Road Trafficability Assessment Using Soil Cone Index, Water Index, and Geospatial Data

Photogrammetric Engineering & Remote Sensing, 2022
Nowadays, the type of vehicles, either tracked or wheeled in the Army has increased considerably and every decision maker wants the current details of off-road trafficability for operation planning. Therefore, vehicle-specific trafficability maps are the

Flow index-liquid limit relationship by fall-cone tests in clay-sand mixtures

Engineering Science and Technology, an International Journal, 2023
The Fall-cone test is a useful method which can be used in evaluation of many soil index and strength identifiers. In this regard, the flow index is calculated as the slope of the plot of water content against natural logarithm of the penetration depth ...

A Cone Penetrometer System for Measuring Cone Index and Stress Relaxation

Transactions of the ASAE, 1989
ABSTRACT Aportable computer controlled cone penetrometer was designed for making cone index and relaxed cone index measurements. The new penetrometer is DC powered and was interfaced to an IBM personal computer. Software was used for controlling the penetrometer motor speed (penetration rate), and sampling cone depth, cone index and stress relaxation ...

A Microcomputer System for Cone Index Measurement

Transactions of the ASAE, 1983
ABSTRACT HIGH soil strength has been shown by many researchers to be a significant soil physical property that reduces crop yields. A fast yet accurate method of determining whether this problem exists in a particular soil is needed for tillage for research and for research involving yield trials.

Cone Index Prediction of Compacted Soils

Transactions of the ASAE, 1988
ABSTRACT THE cone index prediction equation for three soil textures varying in organic matter contents that were subjected to three levels of compaction energy was obtained. The equation is of the form: (CI/Pc) = A (Ts/Qp)^. The functional form of A and n was determined for sandy loam, clay loam and clay for varying moisture contents.
