About Density


The administrative settings and data defined in the Density tab apply to Density Testing and Gauge Standardization.

 

Settings

The Settings area on the Soil tab The Settings area on the Soil tab is where the clientthe client-determined range determined range for Upper and Lower Specified Moisture Compaction % is defined.

 

These  These values are used in the test calculation to determine if Moisture Compaction passes, unless  unless they are overridden by project-specific values in the Project Specifications area.


Test Type

In this section you can activate or deactivate different density Test Types.  For example, if you do not perform Sand Cone testing, you could deactivate this Test Type.

Nuclear Gauges

Nuclear gauges used for field Soil and Bituminous Density testing Testing are managed using the controls in this tab.

Things to keep in mind as you’re you are entering gauges:

  • Each gauge entered must have a unique serial number.
  • Rx Density Limit and Rx Moisture Limit are the manufacturer’s recommended standard count limit for the specific gauge – used in the Standardization calculation in MetaField™.
  • Deactivating or deleting a gauge removes it from the selection list in the Gauge Standardization area.
  • Each gauge must be assigned a Category:  Density or Moisture/Density.  This category will dictate what types of Standard Counts will be required in Field during gauge standardization.

Sand Cones

Sand Cones used for Sand Cone Density Testing are managed using the controls in this tab.

Things to keep in mind as you are entering gauges:

  • Each sand cone entered must have a unique name.
  • The Bulk Density of Sand entered in Admin can be overridden in Field as necessary.
  • Deactivating or deleting a sand cone removes it from the selection list when performing a Sand Cone Test in Field.

Bituminous Material

This is where you define the different types of material on which your organization performs bituminous density testing.  You can define Minimum and Maximum specified compaction at a global level for each material.  These specifications can may be override by project specifications or altered in Field.  You can also identify if a failing bituminous tests will require retesting.

 

Soil Classification 

...

Within Soil Classification you can define a Lower and Upper Moisture Tolerance for all soil classifications.  You will also need to add the soil classification Codes used by your organization.  For each soil classification you can further moisture testing requirements. 

 

Test Administration

The Test Administration area allows you to move Soil Density tests to other projects or delete them. This screen is very wide due to the amount of data shown in the table (similar to the Soil QC table).  Depending on your computer’s screen resolution, some scrolling may be necessary to see everything.

...

Common problems addressed are:

  • Field user enters a Soil Density test on the wrong project.

  • Field user enters an invalid Soil Density test that the project manager wishes to delete.

USCS Exceptions

MetaField™ allows clients to exclude specified soil types from the Moisture test evaluation. 

...

These values are defined within the USCS Exceptions area of the Soil tab.

Exceptions are set up by entering the soil classifications used on Lab Proctor tests. It is extremely important that the exceptions entered use the exact USCS code the lab enters on Proctors.

Based on the soil classification of the Proctor selected for the Field Density test, MetaFieldä determines if only the Density test should be run. 

Common soil types excluded:    SP and SP-SM

Test Administration

  1. Enter the project number of the test(s) to be addressed.

  2. Select the checkbox of the test(s) you would like to delete or move.

  3. Select the appropriate button; Delete, or Move

  4. Follow the resulting prompts.

Tip

When using Test Administration, it is important that you keep the following things in mind:

  • Tests and associated re-tests must always be moved or deleted together.

  • Moving or deleting tests re-numbers the remaining tests on the project.

  • Moving a test to another project will remove the Proctor.  The Proctor must be re-selected from the new project and the test re-run.

  • The entire project number must be entered when using this function
