The Dynamic Cone Penetrometer (DCP) Analysis Tool allows you to analyse and summarise DCP test data. DCP analysis reports can be copied to documents (such as Word) to complement pavement or geotechnical investigation and design reports, or data can be exported to a spreadsheet (Excel) for supplemental analyses.
The key elements of the DCP Analysis Tool are:
- Flexible and visually intuitive identification of layer interfaces
- Immediate assessment of approximate layer characteristics, as determined by the penetration rate (millimetres/blow) and the estimated California Bearing Ratio (CBR) and derived layer Elastic Modulus
- Evaluation of overall structural capacity for low volume roads as determined by the number of blows needed to penetrate to a depth of 800 mm, called the DSN800, based on the research by Kleyn
- Optional comparison of actual and required penetration rates at different depths within the pavement structure, based on subgrade cover requirements as suggested Jordaan’s research
- Ability to handle refusal in one or more layers
- Ability to accommodate actual starting depths below the pavement surface
Getting Started
The DCP Analysis Tool is accessed through the DCP Analysis icon on the Rubicon Toolbox Online Tools.
If this is the first time you are using the Online Tools, you will need to set up a project by clicking on Manage Projects and create a new project. Alternatively, you can use an existing project if one has already been created.
Once you have created a new project or selected an existing project, click on the DCP Analysis icon. The DCP Analysis page will open.
To start, download the example template, enter the relevant data and save the template.
Follow the instructions provided to complete the Excel template. The template covers a range of possible situations that might be encountered in practice. You can enter as many DCP points as you like, with a blank column between each one as shown in the template. Each DCP point must have a unique key in row 1.
Running the Analysis
Once you have completed the template, proceed with the following steps to complete the analysis.
By default, the DCP analysis will display in Single View, i.e. you will be able to view one DCP point at a time. For guidelines on viewing multiple DCP points at a time, use the Multiple View.
Note, Options includes reporting formats, CBR conversion relationship selection, and settings to evaluate the adequacy of in situ strength with depth for a specified traffic demand.
Note, for a new analysis, the Save option is initially inactive. Once an analysis is saved for the first time using Save As, the save option becomes active. To overwrite an existing saved analysis, click on Save. To save as an alternative analysis, click on Save As. Alternatively, you can clone your analysis, from the Online Tools page, and rename it as needed.
The report can be copied to the clipboard by right clicking on the report and selecting Copy image or Save image as. The image can then be inserted into a document of your choice (Word, Excel, etc.). Alternatively, click on Export To Word/Export to Excel to download your reports to a word/excel document.
