title: <b>Intelligent Compaction Measurement Value</b><b> Dataset by </b><b>SPARC Intelligent Compaction Analyzer (ICA)</b>

description: <b>SPARC Intelligent Compaction Analyzer (ICA) Dataset</b><br>This dataset contains compaction-related data collected during the development and testing of the SPARC Intelligent Compaction Analyzer (ICA) kit. The data was gathered through various trials designed to:<br><br>Fine-tune the electronics of the ICA device.Refine and validate data processing algorithms.Research and develop experimental and established Intelligent Compaction Measurement Values (ICMVs).<b>Trial Sequence</b>The trial is conducted on a compaction area approximately 12 meters in length and 4 meters in width, with compaction performed on two lanes (A and B). The recorded data is geotagged using geohashes for spots named A0, A1, …, A12, B0, B1, …, B12. The data is then sorted to these points of interest for analysis.<br><b>Initial Data Collection</b>: ICMV and NDG (Nuclear Density Gauge) data is collected for the existing ground.<b>Excavation</b>: The area is excavated to a depth of 250 mm, and ICMV data is collected as a Premap for the excavated surface (UnderlineLayer).<b>Layer 1 Compaction (Soil)</b>: Soil is placed as Layer 1, compacted up to 6 passes, and ICMV data is collected. At the end NDG data is collected.<b>Layer 2 Compaction (UGM)</b>: UGM is placed as Layer 2 on top of the compacted soil layer, compacted up to 8 passes, and ICMV data is collected. At the end NDG data is collected.<b>Final Data Collection</b>: NDG data and Moisture data are collected at selected points.<b>File Naming Convention</b>Files in this dataset adhere to the following naming structure:[<b>File Information Tags</b>]-[<b>Material Type</b>]-[<b>Layer Information</b>]-[<b>Timestamp</b>].xlsxExample: Filtered_UGM_ExistingLayer_2024-05-23_16_01.xlsx<br><b>File Information Tags</b>: Can include multiple tags describing the processing level or content of the file (e.g., "Raw," "Filtered," "Lanetagged").<b>Material Type</b>: The type of material being compacted (e.g., "UGM" for Unbound Granular Material).<b>Layer Information</b>: Details about the layer being compacted (e.g., "ExistingLayer," "UnderlineLayer," "Layer1").<b>Timestamp</b>: Date and time of data collection in the format YYYY-MM-DD_HH_MM.<b>Data Filtering</b>The "Filtered" data files have undergone the following filtering steps:<b>Speed Filter</b>: Only data points with a speed greater than 0.65 km/h are included. This removes roller idling data based on the GNSS maximum HDOP value.<b>Frequency Filter</b>: Data points are selected where the fundamental frequency (acceleration_A1_f) falls within the range of 29 Hz to 31 Hz. This range corresponds to the roller's vibration frequency during the test and helps eliminate transient vibrations and non-vibration data.<b>Dataset Structure</b><br>[<b>Trial_folder_date</b>]├── [<b>Code_for_plotting</b>]├── [<b>Plots</b>]├── [<b>ICMV_data</b>]│ ├── Raw_[material_type] _[layer]_[timestamp].xlsx│ ├── Filtered_[material_type] _[layer]_[timestamp].xlsx│ ├── Lanetagged_Filtered_[material_type] _[layer]_[timestamp].xlsx│ └── SortedAverage_Lanetagged_Filtered_[material_type] _[layer]_[timestamp].xlsx└── [<b>NDG_Moisture_data</b>]├── Compaction Nuclear Field Report (AS 1289 5.8.1) [material and layer info].xlsx└── Moisture Content Report (AS 1289 2.1.1) [material and layer info].xlsx<br><br><b>Raw_[material_type]_[layer]_[timestamp]</b>: Contains raw data collected by the ICA kit<b>Filtered_[material_type]_[layer]_[timestamp]</b>: Contains speed and frequency filtered data<b>Lanetagged__Filtered _[material_type]_[layer]_[timestamp]</b>: Contains data with lane position tag<b>SortedAverage_Lanetagged_Filtered_[material_type]_[layer]_[timestamp]</b>: averaged data sorted by lane position<b>GeoTag_[material_type]_[layer]_[timestamp]</b>: image showing the relative spatial boundaries of lane position tags<b>Compaction Nuclear Field Report (AS 1289 5.8.1) [material and layer info]</b>: NDG data<b>Moisture Content Report (AS 1289 2.1.1) [material and layer info]</b>: Moisture data<b>Roller Specifications</b><b>Type:</b> Caterpillar CS44B<b>Drum Mass:</b> 3383 kg<b>Eccentric Moment Force:</b> 3.32 kg·m<b>Drum Length:</b> 1.6764 m<b>Drum Radius:</b> 0.6223 m<b>Roller Static Weight:</b> 7209 kg<b>Front Static Weight:</b> 3518 kg<b>Roller Vibration Frequency Range:</b> 23.4-31.9 Hz<b>Roller Maximum Centrifugal Force:</b> 13562 kg<b>Parameter List:</b> Please refer to the ReadMe Document inside the trial folder.<br>
